Abstract

This paper reports a wrist-brace type sandwich structured triboelectric microgenerator (S-TEMG) by optimizing the effective surface area per unit volume for harvesting biomechanical energy from double human skins contact. The working mechanism of proposed harvester is based on the charge transfer between the Au electrode on Polydimethylsiloxane (PDMS) and ground via modulating the separation distance between the tribo-charged human skin and PDMS film. Two micro-structured PDMS films were used to improve the performance of device, which were micro-fabricated by using a sand paper template. Owing to the unique structure design, the as-fabricated prototype is capable of producing voltage up to 150 V and 100 μW peak power at a load resistance of 10 ΜΩ by mild fingers pressing (∼0.2 N force) on the device at around 5 Hz frequency.
