Method and System for Wireless Energy Harvesting and Power Management Using Piezoelectric Components

The present invention relates to a radio frequency energy harvester module. The harvester module receives an AC input voltage from a wireless power source, rectifies it into a DC voltage, and uses a piezoelectric transformer to convert this voltage into a transformed AC signal, which is subsequently rectified to generate a stable DC output. The system includes an oscillator to generate excitation or oscillation signals, matched to the resonance frequency of the piezoelectric transformer. The method includes steps for converting wireless power into usable DC output using rectification, piezoelectric transformation, and feedback-based optimization.
