Abstract

Recently, electrostatic-type vibration energy harvesting (VEH) has attracted much attention. However, the matching impedance of VEH is much higher than that of a sensor circuit. As a result, the transfer efficiency of generated electrical energy from VEH to the load circuit is low. In order to solve this problem, new method that can improve the transfer efficiency of electrical energy generated by the VEH by reducing its internal impedance was studied.
