Kinetic energy harvesting is a promising way to power wireless sensors. In particular, miniature Kinetic Energy Harvesters (KEHs) are of great interest, especially with the development of the Internet of Things (IoT). However, the scaling law is very unfavorable for small energy harvesting systems, since the converted electrical power, extracted from the mechanical domain, decreases roughly with the size of the transducer to the third power. This talk will present our efforts at Université Paris-Est/ESYCOM lab to realize KEH systems with silicon-based MEMS transducers of about 1 cm², using electrostatic transduction and working at low frequencies. Basics of the electrostatic transduction for KEHs, devices with high effectiveness and experiments of self-powered wireless communications will be detailed.
About the Speaker:
Prof. Philippe Basset received his engineering diploma in electronics from ISEN Lille, France, in 1997, his M.Sc and Ph.D from IEMN University of Lille in 1999 and 2003 respectively, in the areas of microelectronic and micro-electro-mechanical-systems (MEMS). In 2004 he was a post-doc at CMU, Pittsburgh, USA. In 2005 he joined ESIEE Paris at the Université Paris-Est, France, where he is an associate professor. His current research interests include micro/nano-structuration of silicon and micro-power sources for autonomous MEMS. He led several projects on these topics and he currently serves in the International Steering Committee of the PowerMEMS conference. Member of the ESYCOM laboratory, he is currently leading the Sensors and Measuring MEMS group.
