Abstract—Harvesting ambient vibration energy through piezo-
electric means is a popular energy harvesting technique which
can potentially supply 10–100’s of
W of available power. One of
the main limitations of existing piezoelectric harvesters is in their
interface circuitry. In this paper, a bias-flip rectifier circuit that
can improve the power extraction capability from piezoelectric
harvesters over conventional full-bridge rectifiers
