Alternative Powering Methods for Miniature Wireless Sensors
Professor Eric M. Yeatman. Imperial College London
As wireless electronic devices continue to proliferate, removing the maintenance burden of battery replacement or wired recharging becomes ever more attractive. Wireless sensors present a particularly compelling application, as in many desired applications they will be large in number, and difficult to access for maintenance, while having modest power requirements. At Imperial College we have developed a variety of alternative powering methods, including kinetic energy harvesters, dynamic thermoelectric harvesters, resonant inductive charging systems, and ultrasonic power delivery. In this talk we will present these methods, and discuss their current and potential performance capability, their suitability for specific applications, and likely future developments.
Eric M. Yeatman has been a member of academic staff in Imperial College London since 1989, and Professor of Micro-Engineering since 2005. He has published more than 200 papers and patents, primarily on optical devices and micro-electro-mechanical systems (MEMS). Since 2015 he is Head of the Department of Electrical and Electronic Engineering. He is a Fellow and a Silver Medalist of the Royal Academy of Engineering, and a Fellow of the IEEE. Prof. Yeatman is also co-founder and director of Microsaic Systems plc, which develops and markets miniature mass spectrometers, based on MEMS technology, for chemical analysis. His current research interests are in energy sources for wireless devices (particularly energy harvesting), MEMS devices and applications, pervasive sensing and sensor networks.
