Abstract :
This paper presents a process of designing a hybrid energy harvesting system for small powered battery applications. The system is constructed with two separate systems that are the mechanical harvesting system and piezoelectric harvesting system. They are coupled together with an efficient power management circuit with the intention to generate electricity through walking while acting as a battery charger. The system has shown positive results when used to charge up a small battery powered electronic gadget such as a mobile phone.
