Switching Delay in Self-Powered Nonlinear Piezoelectric Vibration Energy Harvesting Circuit: Mechanisms, Effects, and Solutions

Piezoelectric vibration energy harvesting (PVEH) has been proved to be much promising in making low power electronics completely self-powered due to wide availability and high energy density. Self-powered synchronized switching harvesting on an inductor (SSHI) circuits have been proved to greatly increase the performance of a PVEH device and peak detector-based self-powered switches are widely used. In practice, however, the switch is impossible...
