|Résumé : Environmentally-friendly technology has been rapidly growing the research area, and many micro and nano technologies have been developed to tackle the environmental problems. These technologies must enable the effective utilization of resources and energy in their realization and their application. The development of the next generation of Microsystems should lead to sustainable, reusable, recyclable and environmental friendly devices and systems. Our focus is to orientate our research program towards technological development for sustainable development. In this seminar we will provide an overview on our activities in the field of MEMS and Microsystems envisioning environmental friendly processes, “green manufacturing”, for the production of MEMS and their environmental applications. Topics on microtechnology aiming at mitigating environmental issues will be addressed.|
We will discuss some issues related to the label green technologies according to the complete life cycle of Microsystems (production, operation, disposal). We will present some ways we are investigating for the realization of sensors using more environmental friendly processes and technology platforms. We will also describe the development and applications of different types of MEMS that could bring benefits to the environment, by enabling reduced emission of pollutants and/or saving energy.
Our core activities in the field of PowerMEMS, energy generation and scavenging, of Silicon Carbide MEMS for Harsh Environments, of micro sensors and micro-analytical instruments for gas detection and of sensors on plastic foils will be presented. The use and development of epitaxial piezoelectric MEMS for energy scavenging, of single crystal silicon carbide sensors for jet engines and turbines, of different types of sensors for environmental and goods monitoring, will be highlighted. We will report as well on our recent advances we have achieved in the development of a multi-sensor platform on plastic foil for environmental monitoring and its interfacing with RFID communication for the realization of autonomous smart sensing systems. The objective is to develop sensor systems realized on flexible substrates that have sensing, communication and powering capabilities. Besides RF and battery powering, energy scavenging is considered for prolonging or replacing batteries for the realisation of autonomous long life sensor nodes. Our System in Foil (SiF) concept for the integration of long life sensor nodes powered by scavenging energy in a flexible credit card planar module will also be introduced.
