About The Seminar:

In this talk, realizations of novel wireless and batteryless microsystem solutions are discussed. Meeting stringent requirements of wireless microsystems such as long operation distance, high bandwidth, high processing capability and low power densities in small batteryless forms is still a big design challenge. In one of my implementation, a single light emitting diode (LED) is used as the power suppy and data transmitter of an application specific integrated circuit (ASIC), that works as a power regulator and temperature sensor. 10 cm wireless working distance has been shown with laser power density of 6 mW/mm2. In my second implementation, operations of optically powered mm-sized wireless and batteryless electromagnetic actuators are demonstrated inside 7 Tesla magnetic resonance imaging (MRI) scanner. My third implementation is on triboelectric energy harvester and how it is used to power two different ASICs with RF transmitter and temperature sensor. Ultrasonic power transfer methods are also mentioned as viable solutions to wireless operation in addition to optical ones, and alternative to RF ones.
