Abstract
This paper introduces a contact separation triboelectric energy harvester (TEH) using a cantilever beam with a groove to work at low-frequency. The designed TEH exhibits broadband behavior which is induced in the cantilever motion due to contact between two triboelectric surfaces. The open-circuit peak output voltage and output power of this fabricated prototype are 64 V and 5.4 μW at low resonant frequency of 13 Hz, respectively, when it matches an optimal loading resistance of 1.2 MΩ under the excitation of 0.9 g acceleration. Moreover, an operating frequency bandwidth of 9.2 Hz for the TEH device can be obtained at an acceleration level of 1.1 g.
