Gyro power generation rotates a weight at high speed and adds tilt vibration due to environmental vibration to generate electric power.

It outputs 10W or more from vibrations of 1Hz or less such as human movements and ocean waves. This is the result of JST / ASTEP / strategic theme priority type “Creation of technology for realizing energy harvesting for IoT and wearable devices”.
