| ABSTRACT |
This converter is a system that can convert the acoustic pressure to direct current. A piezoelectric microphone will be the inut for this system. The good design of piezoelectric microphone needed to make sure the maximum acoustic pressure is entering the system. Iw will make the piezoelectric vibrating and thus produce high output of the system. The motivation of this project is build up a system that can harvest green energy from the enviroment. There are few types of harvesting energy from enviroment such as wind power, solar power, and hydro power. There are also other 2 study case : A Micrimachined Pizoelectric Microphone for Aeroaacoustics Applications and Oiezoelectric microphone built in circular diaphragm that inspired this oriject to be successful.
