Analysis of Discrete & Integrated Circuits for Piezoelectric Energy Harvesting

Abstract: This paper discusses two circuits for piezoelectric energy harvesting; one is integrated circuit which consists of LTC®3588-1; a complete piezoelectric energy harvesting power supply, other one is a discrete circuit. Former one is simulated with the LTSPICE; later one is simulated in Proteus, and both the circuits are practically built and tested in laboratory. Based on the comparative study of these circuits, we suggest the use of integrated circuit in harvesting the mechanical energy (pressure) produced in shock absorbers of bike which could serve as an ancillary source of energy for charging mobile phone battery.
