Накратко на български
Микророботни системи от пьезоелектрични материали се разработват за прецизно управление на обекти в микромащаб, например чрез микрозахвати. Те позволяват едновременното задвижване и измерване на позицията, което подобрява точността и намалява разходите при създаването на микросистеми и микроскопи.

New micro-robotic systems featuring piezoelectric adaptive microstructures for sensing and actuating, with associated embedded control
The main objective of the project MICROPADS is to develop innovative centi / millimetre active structures integrating on the same piezoelectric material both the actuating and the sensing functions, with control laws enabling the achievement of micro / nanometric resolution and high bandwidth(some hundreds of Hz). To achieve these objectives, the project were split into several multidisciplinary tasks: - Research of newer materials and different microfabrication technologies to treat them, for high performances actuators and sensors dedicated to the micro and nano-scale. We derived that PMN-PTPiezoelectric materials combined with silicon would be very promising to develop high performances and embarkable microsystems. These PMN-PT / silicon microsystems, called piezoMEMS, can be easily fabricated using existing micro technologies (laser, reactive ionic etching, saw dicing...) allowing therefore the batch fabrication. - Design of cantilevered microactuators and microgrippers for micromanipulation and microassemblyof micrometric size objects mainly based on a mix of thermal and piezoelectric principles (called hybrid thermopiezoelectric actuator). These innovative microactuators allow a large amplification of the range (up to 5 times more than of classic piezoatcuators) by maintaining the high resolution of positioning. Result: one patent is pending. - The development of embedded measurement systems for piezoelectric microactuators by employing the self-sensing technique. The developed technique, based on a convenient electronic scheme and an observer technique, allows the use of a piezoelectric microsystems as an actuator and sensor at the same time. Results: major improvement of signals, reduction of system costs, possible applications for AFMs microscopy. The self-sensing technique allows a considerable reduction of space of the measurement and control of the Microsystems since the datagate and the sources are both embedded in one electronic board. - Development of microrobotics. We designed and successful tested a mobile microrobot actuated based on the combination of magnetic and piezoelectric effects. Result: we participated to the annual competition of micro / nanorobotics held at IEEE ICRA Conference May 2010 in Alaska. Place: 1st place and world record award for the 2 mm dashed challenge.

Цел на проекта
Adaptronics is a state of the art interdisciplinary area of research. It unites broad principles of structural mechanics, advanced material science (notably piezoelectric), actuation and sensing elements and embedded control technology. Adaptive systems are autonomous self-regulating mechanisms, able to adapt themselves over variations of environmental conditions. Innovative adaptronic systems intend to extend the framework of the possibilities with the development of new products within almost all ranges of the industry. The project focuses on one of the most promising applications of piezoelectric adaptive systems: microrobotics and micro-assembling systems for micrometric components. These systems require a very strict performance such as nanometer resolutions, millisecond response time etc. and the use of precise sensors is indispensable. But, until now, there does not exist a “perfect” sensor neither in industry nor in research, with convenient sizes, precision and dynamics for microrobotic applications. It appears very interesting and innovative to develop centi/millimeter active structures integrating on the same piezoelectric material both the actuating and the sensing functions with embedded control. Such smart systems could be designated as cost-effective, compact and multi-functional, since they handle carrying, sensory and actuating tasks at the same time. The subject of the proposed research is multi-disciplinary and seeks a series of specific approaches for improving the overall microrobotic performance. As described in the proposal, it touches several areas: mathematical modeling, multiphysics design, microtechnology, theory of automatic control and software development, according to host institution expertise and researcher career.
