Microsystems for power generation

Final Project Workshop SBO 030288

The evolution towards miniaturisation, portability and ubiquitous intelligence has created the need for miniaturised power generators that exceed batteries in energy density and
compactness. The PowerMEMS project has developed (technologies for) two types of microgenerators: ultra-microgasturbines ranging from a few 100 W to ultimately 1 kW, and
power scavenging microsystems in the ìW range. This final workshop is organized accordingly: the first session is dedicated to ultra-microgasturbine technology and the
second session to MEMS energy scavengers.
