Development of New Piezoelectric/Magnetostrictive Materials for Wearable IoT Devices

Wearable IoT (Internet of Things) devices for sports require vibration energy harvesting technology that is lightweight and able to withstand vigorous exercise, and innovative design that will allow wireless wearable communication to and from athletes. At our lab, we are working together with a sports equipment manufacturer to create carbon fiber reinforced polymer (CFRP) with piezoelectric/magnetostrictive properties (energy harvesting new material). Our goal is to develop next generation sports equipment (rackets, shoes) which incorporates 1) high quality energy harvester/sensor, 2) rectifier/power storage circuit, 3) short range transceiver module.
