Abstract

Batteries are one of the most popular power supplies for its portability and convenience. However, batteries have limited life and need to either be replaced, recharged or both which has ongoing costs associated. There is an alternative way to harvest electrical energy which is using piezoelectric material. The disadvantage is that energy harvested from piezoelectric energy harvester is in AC form and it is too low to charge up electronic devices such as smartphones. The project aims to design and develop a prototype that able to harvest electrical energy from human walking movement using piezoelectric materials. Firstly, a prototype of piezoelectric kneejoint energy harvester is developed to harvest electrical energy. The harvested energy will be rectified to 3.3V and stored into a super capacitor. The circuit will be used to power up a Radio frequency system to verify that there is sufficient output power from the circuit designed.
