Abstract

Battery always been the first choice for every low electronic device such as remote control, watches and etc. However, battery has limited lifespan and pollute the environment after disposal. One of the alternative ways is replacing battery is by using energy harvester that utilize the energy produced by the piezoelectric cantilever. The piezoelectric cantilever is able to generate electric charge in response to applied mechanical stress. However, the power produced by the piezoelectric is in AC form, which is not suitable for DC powered electronic device. Moreover, the vibration produce by the cantilever is inconsistent and random. Therefore, the aim of this project is to produce a piezoelectric micro-generator in the form of cantilever that able to power up the application with the energy harvested from ambient vibration sources and characterize the cantilever to have wider operating frequency band. The AC voltage is converted to DC voltage with a rectifier and stored in a supercapacitor up to 3.3V. The project was able to power up RF transmitter to send out signal with the energy stored in the supercapacitor.
