Abstract:

Hydro-climatic extremes, such as droughts and floods, have increased due to climate change and could lead to severe impacts on socio-economic, structural, and environmental sectors. Soil water assessment models have shown that pesticides are transported into waterways because of intense rainfall events. Current monitoring methods are not suited to the detection of such water quality impacts, which can deplete invertebrate populations and impact biodiversity and ecosystem health very rapidly. Many surface- and groundwaters are used as sources of drinking water, and therefore the occurrence of chemicals is problematic for water treatment facilities. Rapid, real-time sensing technologies do not exist yet but are urgently needed to address this. In October 2022 revisions to the priority pollutant Annex to the Water Framework Directive (WFD), saw the addition of noenicitinoid and pyrethroid pesticides, showing that pesticides are of growing concern. The STARDUST project aims to develop a first-of-its-kind, integrated optical system combined with smart spectral data processing methodology, for multiplexed monitoring of pesticides in surface and ground waters, and to understand the impact of extreme hydroclimatic events on water quality in the context of pesticides occurrence. We will develop a sensor based on surface-enhanced Raman spectroscopy fully integrated with microfluidics targeting the detection of pesticides, pesticide mixtures, and metabolites in surface and ground waters. Secondly, we will use rainfall forecasts to identify sampling times for passive sampling and citizen scientist co-created events, to gather samples that are specifically linked to rainfall events. This will build on existing monitoring programs, but, more critically, will identify the climate-related water quality impacts. The results of passive sampling will identify target pesticide compounds to be addressed with the developed novel sensor and a database of detected pesticides will be compiled and shared publicly. The STARDUST project translates several technological advances into an innovative solution for discrimination between safe and contaminated water continuously and in real time. We envision that in the long run, any strategies for mitigation of the hydro-climatic extreme events will need to rely on digitalization and sensors. The proposed activities will benefit a wide range of “problem owners” and society by responding to the need for continuously clean water (SDG 6). Pesticide detection is only one of the existing problems. The proposed solution is also applicable to other harmful compounds adding value and impact. STARDUST primarily targets the topic 2 of the call by proposing physical and digital solutions for “smartening the water system”, but also contributes to the topic 1 as the development will be carried out in the context of adaptation and mitigation strategies to cope with hydro-climatic extreme events, and both experts on the analysis of surface and ground waters are involved.

Abstract:

Formaldehyde (CH2O) is a harmful and toxic volatile organic compound, which brings serious concerns regarding the human health and the living environment, due to its carcinogenic effect. Since 2010, formaldehyde is considered a Group 1 carcinogen by the World Health Organization (WHO), and also one of the major indoor air pollutants in the WHO guidelines for indoor air quality, with a very low concentration limit of 80 ppb. Therefore, there is an urgent need for sensitive and selective monitoring methods. The standard analytical techniques currently in use for CH2O detection (spectrophotometry, chromatography or polarography) require expensive instrumentation and well-trained operators. The proposed project (FormalSens) will develop a novel approach, integrating resonant SAW devices with graphitic carbon nitride (g-C3N4) decorated with zinc oxide (ZnO) nanoparticles, providing high sensitivity, low operating temperature and excellent selectivity. Moreover, the system will allow CH2O detection in the presence of interfering species (NH3, NO2, CO) and different humidity levels (20-80%), making it suitable for real environmental conditions. The method proposed by FormalSens (starting from TRL 2 and advancing to TRL 4) will address the major issues of the formaldehyde indoor air pollution by its efficient monitoring in accordance to the increasingly severe international environmental regulations.

Abstract:

Air pollution has been identified as one of the major environmental issues, with significant impact on human health. Rapid industrial development and emission of various harmful gases from vehicles have led to the emergence of various diseases. Nitrogen dioxide (NO2) is one of the most dangerous air pollutants, released by combustion processes, which causes severe respiratory diseases and contributes to acid rains and ozone formation, increasing smog level (a global issue, especially in China). An innovative gas sensor based on the integration of nanocrystalline graphite (NCG) with Surface Acoustic Wave (SAW) devices is proposed for the NO2 sensitive and selective detection. The high sensitivity of the sensor will be provided both by using SAW devices, which confine the acoustic energy to the sensing surface, resulting an increased sensitivity to surface perturbation, and by the deposition of NCG sensing films, with vertically arranged walls, which enhance specific surface area, improving the sensor's sensitivity. The sensors’ selectivity will be conferred by the graphite nanowalls containing graphitic units with increased surface electron density, which interact with NO2 molecules presenting electron withdrawing effects, for an efficient adsorption on the surface’s sensor. The scientific challenges include sensing NCG synthesis, with tailored properties, NCG-SAW sensors development, using a novel approach, and the device’s sensing performances evaluation.

Abstract:

The overuse of glyphosate (Gly), a nonselective and broad-spectrum herbicide widely used to control weeds in grain crops, has induced issues, such as contamination of surface water, decreased soil fertility, adverse effects on soil microbiota and possible incorporation in food chains. The maximum residue thresholds of Gly are established at the very low concentration, especially for drinking water (0.1 μg/L or 0.6 nM, in European countries), therefore there is an urgent need for sensitive and selective monitoring methods. The proposed project (GLYSens) will develop and validate a sensitive, selective and fast responsive sensor based on shear horizontal (SH) Surface Acoustic Wave (SAW) device for the detection of Gly from water samples (collected from basin of Olt river, the most impacted region in Romania). The high sensitivity of the sensor will be assured by both design and piezoelectric substrate, together with the guiding layer (SiO2, polymer or ZnO), while the selectivity will be provided by using thin layers of molecular imprinting polymers (MIPs), generally considered as artificial mimics that are comparable to the natural receptor, providing more stable and low-cost recognition elements. Since the water samples are very complex matrices, the selectivity study is a must and for this, GLYSens will investigate several possible interfering species, such as different herbicides, organic contaminants or metal ions, known to coexist in the water matrix. Also, more than 50 water samples will be analyzed using the developed MIP-SAW sensor, and for the validation of the method, the obtained results will be compared with the results obtained from one standard method (Ultra-High Performance Liquid Chromatography- Mass Spectrometry).

Abstract:

In recent years, terrorist attacks primary based on releasing explosives and chemical warfare agents in the public happened frequently which makes it imminent to develop chemical sensors for the high selective and sensitive detection of warfare agents (WAs). Chemical warfare agents include blood agents, blister agents, and nerve agents including sarin and VX. Considering sarin’s gas high toxicity, DMMP (dimethyl methylphosphonate), an organophosphorus compound, is widely used as its simulant in the laboratory because of its similar chemical structure and much lower toxicity. Because the use of chemical warfare agents are impossible to predict or prevent, is required to design and synthesized of novel and improved materials that allow developing of more fast sensing systems with high selectivity, low-cost and on-site portable. Perovskite materials with outstanding properties have become significant candidates for developing platforms of the detection of toxic agents. Thus, the aim of the WAsSens project is development and testing a technology validated in the laboratory namely, a SH-SAW sensor, using undoped and Co or Sn doped ABO3 perovskite ceramics materials (A = Y; B = Mn) , obtained through low cost and environmentally friendly processes. To achieve the aim of the project, the overall objectives are: (i) Obtaining of perovskite structure through sustainable and green processes; (ii) Deposition of perovskite materials on quartz substrate in order to achieve thin films; (iii) Design, achievement and testing of SH-SAW sensor used for selective detection of the sarin gas simulant - DMMP; (iv) Dissemination of the research results. Project outcomes will materialize by advanced synthesis technologies, production processes and innovative products, and also in creating mechanism for implementation of scientific results in production. The expected outcomes will consist of innovative technologies and demonstrative models, in order to validate the proof of concept (TLR).

Abstract:

The modern technology for gas sensing is gaining more and more attraction, both at commercial and academic levels, as one of the most emerging application in smart systems. Since the environmental aspects are one of the biggest concerns nowadays, new ways to detect and monitor ambient air pollutants and toxic gases became critical. One of the most dangerous species amongst them is nitrogen dioxide (NO2), which has a major negative effect on the environment. NO2 is accountable for acidic rains, ozone formation and is a major environmental cause of morbidity and mortality worldwide, even in low concentrations, if there is a repetitive or long-term exposure.

The main objective of the project is to develop highly sensitive room-temperature NO2 gas SAW sensors based on transferred CVD graphene. The scope of the project is to increase the device integration and combination with other 2D material(s), decreasing the cost and size, targeting new opportunities in addressing societal challenges (environmental, health). The scientific and technological challenges include material deposition and transfer, with targeted properties, material characterization, as well as device design, processing and characterization, using a novel approach, allowing us to reach the expected enhanced device performances.

Abstract:

If current production and waste management trends continue, it is projected that roughly 12 billion metric tons of plastic waste will be in landfills or in the natural environment by 2050. Plastics represent a significant environmental problem: They are for the most part not biodegradable, cause problems for terrestrial and aquatic life, and enter the food chain in the form of microplastics. A shift towards a circular economy has been proposed to meet these challenges, in which production, circulation and consumption do not leave behind negative footprints and do not deplete natural resources. An essential component in the transition to a circular economy involves turning waste into value, thereby giving incentives to reduce, reuse and recycle. Simplified and low-cost methods of sorting materials are currently making a great impact on the environment: It is estimated that the reverse vending machines of the company TOMRA alone capture 35 billion beverage containers every year, and thereby reduce greenhouse gas emissions by an equivalent of 2 million cars driving 10'000km annually.

Photonic sensors are ideally suited for material sorting due to the spectroscopy technique, which allows for discrimination between different polymer types by illuminating with near infrared electromagnetic fields and measuring absorption. An important development goal is to make such spectroscopy simple, affordable and energy efficient. The ElastoMETA project aims to design and fabricate functional nanostructured surfaces, known as metasurfaces, to meet these goals. These surfaces contain simple subwavelength nano-structures that can shape light which is transmitted through them. Despite their simplicity, they offer a new paradigm for advanced field manipulation due to unprecedented control of phase, polarization, amplitude and dispersion of the electromagnetic fields. The versatility of this approach is evident by the short time during which numerous realizations have been made: e.g. micro-lenses, filters, couplers, emitters and even holograms. With further development, metasurfaces are expected to have several advantages over existing optical sensor technologies for recycling applications (e.g. diffractive optics), in terms of (i) increased efficiency, (ii) relative ease of fabrication, and (iii) enhanced functionality.

The ElastoMETA project aims to develop designs and cost-effective nanostructuring processes for (a) tuneable, filtering and efficient lens designs, and (b) directional infrared emitters, for plastic detection. These developments are central to improving the efficiency and functionality of a spectroscopic microsensor for a circular economy. To this end ElastoMETA combines Romanian expertise in UV-nanoimprint and electron beam lithography from the National R&D Institute of Materials Physics (INCDFM) and the National R&D Institute in Microtechnology (IMT), and in theoretical photonics at University of Bucharest (UB) with Norwegian expertise at SINTEF Microsystems and Nanotechnology (SINTEF MiNaLab) in developing micro-optical sensor devices for industrial plastic and gas detection. This new long-term strategic partnership aims to bring developments at the forefront of photonics and nanotechnology towards commercial sensor applications for a competitive Romanian and Norwegian industry within the circular economy.

ElastoMETA demands close collaboration of the Romanian and Norwegian partners on interdisciplinary and interrelated work, related to i) design and simulation of functional structures acting as tunable, filtering lenses and directional sources, 2) process development using electron beam lithography for design verification, 3) UV nanoimprint lithography for cost effective nanostructuring of large area lenses, 4) embedding structures in elastomeric substrates to allow for mechanical tuneability 5) optical characterization and testing of the manufactured structures and 6) dissemination and evaluation of the project.

Abstract:

The project ResoSens aims to develop a novel structure model of resonant sensors with substrate integrated waveguides (SIW) using the “virtual impedance” concept previously proposed in a funded PED research project and currently developed in a pending patent. Compared to the existing models, our original structure consists of two electromagnetically coupled SIW circuits combined into the same resonant circuit. Major advantage of this configuration is given by adjusting sensor’s resonant frequency by either variation of a single component value, or even providing continuous electronic tuning of the resonant frequency, without requiring any layout modification. Additionally, the sensors can be used for physical parameters’ sensing which currently don’t present implementation solutions. The two coupled SIW resonant structures can be used as resonant sensors by themselves as well as integrated with interdigitated (IDT) transducers covered by thin oxidic films for increased sensitivity.

ResoSens project involves two major research stages. First of all, the actual technical potential of sensors’ structure will be investigated, since their novel layout configuration needs solid and adequate theoretical and experimental support. Consequently, 3-D advanced electromagnetic simulations and their validation on experimental models will allow the validation and improvement of the circuit models. Second research stage involves design, fabrication and electrical characterization of resonant sensor functional model as well as optimization for final validation of proposed concept device. Resonant proposed sensors will work within 5.15 – 5.725 GHz frequency band, which is specific to unlicensed short-range devices intended for wireless applications.

Abstract:

Last decades brought a considerable development of technologies based on ordered systems. Starting with semiconductor physics and photovoltaics, technologies soon evolved towards the utilisation on large scale of thin films and of surface / interface properties. Example go nowadays from data storage and readout (electrostatic or magnetic memories, giant magnetoresistance) to catalysis, gas sensors or photocatalysis (surface phenomena), and towards interfaces with biological matter (biosensors, templates for tissue reconstruction, interfaces between biological electrical signals and microelectronics). In Romania, crystal growth is performed since half a century; nevertheless, during the last years these activities fade out and need to be seriously reinforced, especially with the advent of new laser and detector technologies required by the Extreme Light Infrastructure facilities. Also, surface science started to be developped seriously only during the last decade, together with techniques involving self-organized nanoparticles, nanoparticle production etc. The main goal of this Project is to gather the relevant experience from the five partners, namely the experience in crystal growth from the University of Timișoara, with the surface science, nanoparticle and nanowire technologies developped by NI of Materials Physics, the cryogenic and ultrahigh vacuum techniques provided by the NI for Cryogenic and Isotopic Technologie, and the experience in ordered 2D systems (graphene and the like) owned by the NI for Microtechnologies (IMT). This common agenda will result in a coherent fostering of technologies relying on ordered systems of variable dimensionalities: 0D i.e. clusters or nanoparticles, including quantum dots; 1D i.e. free and supported nanowires and nanofibers; 2D: surfaces, interfaces and graphene-like systems; and 3D crystals of actual technological interest, together with setting up new ultrahigh vacuum, surface science and electron spectroscopy techniques.

Abstract:

The development of complex nanocomposite materials consisting of different matrices (polymer-like, oxides, intermetallics, liquids) functionalized by different nasnostructured additions (carbon allotropes, magnetic nanoparticles with different organizations, nanostructured semiconductors, etc.) is the aim of this project. The unique combinations of interacting nanophases offeres to the hybrid nanocomposite material new or enhanced proprieties of high interest for applications. In this context, according to the previous experience of the involved teams, the complex project (formed by 4 component projects) is focused on the development of new optimized nanocomposite systems to be included in experimental demonstrators or final products to be transferred to economical companies. The project will contribute both to an increased scientific visibility of the partners as well as to enhancing the institutional performances by the development of new technical and scientific capacities.

Abstract:

We intend to develop a wearable device that will allow 1) blood pressure (BP) monitoring and 2) prediction of hypertension conditions during pregnancy.

A first innovative aspect is that we will develop an innovative sensor array for continuous BP monitoring that will come as an improved solution, because the sensing area will cover a large surface of the inner wrist, as compared to other BP sensors on the market, where, the sensing spot has a very small area and could report erroneous measurements due to misalignment with the wrist artery.

The second innovational aspect of our product will be in the application. It will be first continuous monitor for hypertensive conditions throughout the entire pregnancy. The current practice is that serial BP measurements are performed during the second and third trimester, in order to detect an abnormal BP trend over time. We plan to develop and implement a prediction algorithm that will be able to signal alerts much sooner, in order to allow for early preventive actions.

All the above considered, there is no similar solution available on the market. Our product will be affordable, technologically advanced, scalable and open. We´ll position our product based on previously collected consumer preferences, with a maximum differentiation from rivals in terms of price, simplicity and functionality.

In conclusion,we propose the development of a sensor system for the early detection of hypertensive disorders of pregnancy such as pre-eclampsia and other blood pressure as well. The system will consist of a bracelet that incorporates a pressure sensor for continuous recording of the blood pressure wave form across the wrist artery. The resulting data will be sent via wireless connection to a smart phone or a computer. A software application will be developed to predict early signs of disorders.

Abstract:

The main objective of the RoboCom++ proposal is to lay the foundation for a future global interdisciplinary research programme (e.g., a FET-Flagship project) on a new science-based transformative Robotics, to be launched by the end of the H2020 Programme. RoboCom++ will gather the community and organise the knowledge necessary to rethink the design principles and fabrication technologies of future robots. RoboCom++ will aim at developing the cooperative robots (or Companion Robots) of the year 2030, by fostering a deeply multidisciplinary, transnational and federated effort. The mechatronic paradigm adopted today, although successful, may prevent a wider use of robotic systems. For example, system complexity increases with functions, leading to more than linearly increasing costs and power usage and decreasing robustness. RoboCom++ will pursue a radically new design paradigm, grounded in the scientific studies of intelligence in nature. This approach will allow achieving complex functionalities in a new bodyware with limited use of computing resources, mass and energy, with the aim of exploiting compliance instead of fighting it. Simplification mechanisms will be based on the concepts of embodied intelligence, morphological computation, simplexity, and evolutionary and developmental approaches.

Exploring these concepts in order to develop new scientific knowledge and new robots that can effectively negotiate natural environments, better interact with human beings, and provide services and support in a variety of real-world, real-life activities, requires a coordinated and federated initiative. Ultimately, the Companion Robots conceived in RoboCom++ may foster a new wave of economic growth in Europe by boosting the deployment of ubiquitous robots and web-based robotic services.

The RoboCom++ community will pursue these ambitious objectives by cooperating along three main lines of action: 1) building the community and the tools for research reproducibility (benchmarks, metrics, data sharing protocols, test platforms, standards); 2) proof-of-concept research pilots; and 3) defining the long-term S&T roadmap, competitiveness strategy, governing and financing structure, and the ethical, legal, economic and social framework of a future FET Flagship –like initiative on Robotics .

RoboCom++ will actively pursue collaboration with industry, along with dissemination, community outreach and participation of EU citizens and stakeholders, with particular attention to the issue of robots and jobs, and to the analysis and proposition of viable policy options.

Abstract:

Two of the major failure causes of MEMS switches are: contact fatigue and stiction. The adhesion effect which is responsible for the stiction failure of MEMS switches is a major issue for micro and especially nano- switches. The surface properties, the materials of electrodes and the optimal energy for commutation of MEMS switches have to be adequate estimated in order to avoid the collapse of the flexible electrode to substrate after the driving force is removed. Based on the effects which have to be considered in MEMS switches, from the interfacial forces (capillary, van der Waals, Casimir and electrostatic forces) and topography of surfaces (roughness, flatness) to the material properties and manufacturing conditions, the stiction effect still remain a major concern in MEMS. If the materials of electrode are not adequate for switching applications and the operating conditions are not properly, the lifetime of MEMS switch is very short.

The main scope of the project is the accuracy characterization of the mechanical and tribological properties of MEMS materials, their correlation with MEMS switch structures and the analysis of interatomic contact behavior, considering multiphysics electro-thermo-mechanic coupling in order to obtain an excellent reliability as well as a high lifetime. Interatomic coherence between electrodes during switching is investigated. Nanotribological investigations include adhesion, friction and wear measurements of MEMS switch materials in different operating conditions. The actuation of this MEMS switches is based on the out-of-the plane displacement of the mobile electrode under a thermal gradient generated by the applied actuation voltage. It can be used either as a capacitive switch or as a metal-to-metal one. The out-of-plane thermal MEMS switches can be monolithically integrated in RF applications. At the end of project a prototype of a reliable MEMS chevron type switch with high lifetime will be a delivered.

Abstract:

One of the dominant factor in improving CO2 emissions and fuel consumption is the reducing the weight of the car. By subtracting 50kg from total mass of the car ones could obtain a reduction of 5g CO2/km and 0,1 l/100km in fuel consumption. A reduction of 100kg of car mass allows the reach of 100km/h speed faster by 1 second. Having these coordinates it is obvious that the future cars must be lighter, and to obtain this kind of mass reduction it is necessary to use new materials.

Therefore, the project is dedicated to two demonstrators starting from TRL 2 and reaching TRL 4 to be developed with Renalut Technologies Romania (RTR) having the following aims (i) on demonstrator is graphene-polymer composite for replacing cooper in the car with very light cables (ii) a thermal isolator and fire retard nanomaterial based on graphene-nanocellulose composites.Overall, TRT estimates that 50 % of weight of the cables and thermal isolation will be reduced in this way. Intensive electromagnetic, electrical, and thermal tests will be made using these demonstrators. The final test will be done at RTR automotive testing center of cars.

Abstract:

The main purpose of the project is to develop a robotic micromanipulation system with MEMS micro-grippers integrated with microsensors for position/force feedback control for cell manipulation. This will be achieved by developing a set of electro-thermally actuated end-effFectors with different functions (pick and place, pushing-pulling, gripping), in different configurations to be integrated in a robotic micromanipulation system. The end-effector and the integrated sensors will be designed and build at the system level, due to their interdependence not only at functional level but also considering the fabrication technology and component materials. Our implementations will integrate a micro-gripper with different sensing functionalities (force, displacement), the maximum attempt being the full instrumentation of the system. The demonstrator will be used for tailored functionalization of medical devices with cells, in demanded regions.

Abstract:

The objective of the project is design, fabrication and testing a micro-electro-fluidic system for biological cells separation and for membrane permeabilization by electroporation to release cellular content for laboratory or research analysis. Functionality of such system is based on separation by dielectrophoresis of cells in fluid media, on membrane electroporation by applying an electric field and on evaluation of electroporation efficiency by electrical and optical methods, using functionalized ferromagnetic nanoparticles for cell capture. At the present, the separation technique by dielectrophoresis is performed by using structures with channels where the electrodes are placed on the surface in contact to substrate. Electroporation is realized by permeabilization of the membrane as effect of electrical pulses, and its scope is either transfection or releasing cellular content. Microfluidic systems that use both techniques are rarely, and, related to those that are developed until now, the electrodes used for electroporation are distinct from the electrodes used for dielectrophoresis due to difference in applications, despite the fact that this approach needs complex fabrication methods. Still, implementing both techniques on a chip is a requirement of such systems, while reducing the number of electrodes shall contribute to simplify fabrication methods, reducing costs and facilitate the use of dielectrophoresis in selective manipulation of cells, in order to evaluate permeabilization efficiency.

In this context, the general objectives of the project are: - Design, simulation and optimization of an experimental model of micro-electro-fluidic system with multifunctional electrodes that ensure both manipulation / separation and electroporation; - Masks design and realization; - Technological design and fabrication of optimized microsystems using MEMS technologies; - Microphysical characterization; developing methods for electroporated cells quantification and for determination of dielectric and optical properties after electroporation; - Synthesis, characterization and functionalization of ferromagnetic nanoparticles with specific antibodies for cells capture; - Cells preparation and characterization of dielectric and biophysical properties before and after electroporation; - Testing micro-electro-fluidic system, electroporated cells quantification by alternate methods (electrical, optical) and correlation of results.

The project requests integration of multi-disciplinary theoretical and technical knowledge: microfluidics, electric field effects, mathematical and numerical modelling, microtechnologies for microsystems fabrication, biology, biochemistry, biophysics, nanoparticles syntetization and characterization, optics. By comparison to conventional devices, the microsystem proposed for fabrication and testing offers advantages such as reduced fabrication costs due to simplified electrodes, low power consumption, reduction of heating effects, better control on electrical parameters, implying increased efficiency and precision. The microsystem can be integrated in lab-on-chip devices or sensors for biochemical analysis, diagnosis of cellular properties and content or therapy by transfection. Last, but not least, the research can give answers to questions related to dielectric properties variation of electroporated cells or to selective separation means of electroporated versus unmodified cells.

Abstract:

Although appealing, MEMS sensors suffer from uncertainties in the geometrical dimensions, surface topologies, as well as material properties of MEMS devices after production. This affects their behaviour and reduces the production yield, leading to an increase inthe manufacturing cost. At the

same time, devices such as microphones and accelerometers, used in mobile phones, are under a tremendous price pressure. Since 2004, prices have dropped by 50%. While testing is viewed to be a practical solution to reliability assurance of MEMS, cost for developing effective and reliable

testing remains high and is estimated at over 40% of total production costs, mainly because the equipments for tests are really expensive and because the tests are very device specific This project aims atimproving the efficiency of the manufacturing process while decreasing the

production cost by considering at the design stage the uncertainties in such a way that a range of the MEMS properties can be predicted for the manufactured products, which will be immunetofactors that could adversely affect performance. This approach is called robust design and it is focused on achieving target reliability.

This project will focus on vibrating micro-sensors, by developing a robust design for guarantying:

# The statistical range of quality factor actually reached by the manufacturing process. Indeed, quality of the sensors strongly depends on this value, whichshould reach a minimum threshold.

# The reduced risk of release stiction of the produced MEMS. Due to their large surface area-tovolume ratio, and micro/nano scales involved, MEMS are vulnerable to the micro-meter ranged surface forces (capillary, van der Waals,#), which can lead to permanent adhesion, even at the

manufacturing stage (release stiction).

Due to the multi-physics, multi-scalenature of MEMS and due to the uncertainties in material structures, geometrical dimensions etc, a traditional deterministic approachcannot be used to achieve the robust design. Thus a stochastic finite-element method (FEM) that uses a sensitivity

analysisof theresponse with respect to the random parameters, will be developed. The uncertainty on the properties has to be determined from the uncertainties on the micro-structure of the material (grain size, grain orientation, inclusions#) to characterize the spatialvariationof properties

at the meso-scale. The stochastic FEM will use these data to compute the macro-scale variation of the structureresponse, resulting in a 3-scale (micro-meso-macro) methodology.

Such a non-deterministic approach will be achieved after introducing the following innovations

# Development of original micro-meso-macro stochastic finite element methods. Multi-physics stochastic finiteelements (SFE) will be used to determine the quality factor expected range and release stiction risk will be evaluatedfrom anenhanced contact-adhesion micro-scale model.

# Database collection of uncertainties for given MEMS devices

# Validation by extensivemeasurements on produced vibrating micro-sensors will be achieved by experimental measurements using a laser vibro-meter. Release stiction probability predicted will be compared to measurement from beam array productions.

The final deliverable will bean optimized design of an existing sensor as well as the evaluation of development/manufacturing/exploitation cost reduction.
