Abstract

The present invention relates to piezoelectric power generators. In one embodiment, the piezoelectric power generator comprises a piezoelectric module for generating electrical energy from a mechanical stimulus. Further, the power generator comprises a PCB coupled with the piezoelectric module configured to receive the electrical energy of low potential and converting the same into high potential voltage via a power conditioning circuit embedded within the PCB. The power conditioning circuit comprises a rectifier for rectifying the input voltage, and a voltage converter for stepping the voltage from low potential to a high potential. The voltage converter operates in a discontinuous mode resulting in resistive impedance matching. The power generator can be personnel wearable due to its compact size and less weight.
