Piezoelectric Energy Harvester

Piezoelectric Energy Harvester


Overview

Piezoelectric Energy Harvester, PEH has been used to feed loads in military, health, animal detector, and many other applications. Many techniques have been used to extract the maximum power from piezoelectric, PZT material. A new SP-SSHI has been introduced in this patent using two capacitors to detect the flipping points of terminal voltage replacing many active elements in the other two circuits such as resistors, diodes, and op-amp. The new circuit showed a great reduction in losses, increased output power, increased efficiency, low cost, and increased reliability. The simulation results showed the superiority of the new circuit.
