Abstract

As the power requirements for microelectronics continue decreasing, environmental energy sources can begin to replace batteries in certain wearable subsystems. In this paper we report on a shoe power generator based on a micro structured piezoelectric polymer transducer. The properties of the transducer match regular shoe filling and it is designed to harness energy from human walk without affecting the user´s gait. The generated power is regulated with a self-powered dc/dc conversion circuit that achieves a high 65% efficiency for converting the high piezo electrically generated voltage (130 V) to a low voltage (4 V) suitable for portable electronic devices.
