Piezoelectric Micro Power Generator for Energy Harvesting

A thin film lead zirconate titanate Pb(Zr,Ti)O3 (PZT), power generating device is developed. It is designed to resonate at specific vibrational frequencies from an ambient, vibrational energy source, thereby creating electrical energy via the piezoelectric effect. The energy harvesting device uses the piezoelectric d33 mode and is fabricated with three mask steps. Our cantilever device was desi...

Development of Piezoelectric Micro-energy Harvesting System Using Voltage Doubler

Nowadays renewable micro-energy harvesting system is becoming attractive, because this energy is free which leads to reduce energy cost. Piezoelectric is one of the common energy harvesting systems. Generally, the output of a piezoelectric transducer is a small AC voltage and its power is also small. As a result, the convertion of this low AC voltage into DC voltage by using rectifier diode is ...

Non Linear Techniques for Increasing Harvesting Energy from Piezoelectric and Electromagnetic Micro-Power-Generators

Non-linear techniques are used to optimize the harvested energy from piezoelectric and electromagnetic generators. This paper introduces an analytical study for the voltage amplification obtained from these techniques. The analytical study is experimentally validated using a macro model of piezoelectric generator. Moreover, the integration influences on these techniques is studied. Through all ...
