Chip-Scale MEMS Receivers for Low-Power Wireless Charging

There is an increasing demand for wireless power charging of mobile electronic devices, electric vehicles, biomedical implants and IoT sensor networks. Many of the already available wireless power transmission systems are based on inductive coupling and the size ranges in the cm’s scale, linked to the large surface area requirement. A competing technology is based on an RF approach, with small size chip but impractical power levels of pW to µW, and efficiency close to unity. The alternative working principle that we propose results in a more compact solution that can be reduced to mm’s chip size while producing reasonable output power (1 mW range) at low frequency ranges (50 Hz to 1 kHz).

We have developed an electrodynamic wireless power transmission (EWPT) system that relies on the magnetic-to-mechanic-to electrical conversion from a transmitter to a remote resonator, through electrodynamic transduction. The mechanical motion of a permanent magnet is converted into electrical power, when the magnet is set in motion/rotation, by a time-varying magnetic field, next to the receiver windings.

We congratulate Dr. Toshi Nishida for his new appointment as Interim Associate Dean of Academic Affairs, beginning July 15, 2017. Dr. Nishida is Professor and Associate Chair of Research in the Department of Electrical and Computer Engineering (ECE) and an Affiliate Professor in the Department of Mechanical and Aerospace Engineering (MAE) at the University of Florida. He received his Ph.D. (1988) and M.S. degrees in Electrical and Computer engineering and B.S. degree in Engineering Physics at the University of Illinois at Urbana-Champaign. With colleagues and students, he has published over 150 refereed journal and conference papers and received three best paper awards. He has mentored 23 PhD students. His current research portfolio with graduate students includes high performance multifunctional semiconductor devices and systems, low power memory and device technologies, and novel three-dimensional fabrication. He has 11 issued U.S. patents. Dr. Nishida is the Director of the NSF Industry/University Cooperative Research Center on Multi-functional Integrated System Technology (MIST) launched in 2014 (www.mist-center.org). The vision of the MIST Center is innovating More than Moore technologies for smart systems in the Internet of Things era. He is a co-founder of the Interdisciplinary Microsystems Group. He received the 2003 College of Engineering Teacher of the Year award, the 2017 University of Florida Term Professorship award, and is an Alan Hastings Faculty Fellow. He is a senior member of the IEEE.
