A Contact-Separation Mode Triboelectric Nanogenerator For Ocean Wave Impact Energy Harvesting

This paper describes the effect of ocean wave impact compressed air bubbles on the output performance of a dielectric-metal contact separation mode triboelectric nanogenerator (DMCS-TENG). The triboelectric effect is generated by regular, non-uniform contact between a negative polyimide dielectric layer of easy gaining electrons and positive Aluminum foil of easy losing electrons according the triboelectric series, where the electrical performance changes in proportion to the mechanical energy applied by oscillatory frequencies. At the range of operation of 30 Hz to 300 Hz, the open-circuit voltage, short-circuit current, power and output power density of the device can reach to 3.83 V, 80.38 mu A, 307.88 mu W and 19.24 mu W/cm(2), respectively for a load resistance of 10 MO. The proposed work demonstrates that the device can function as an energy harvesting mechanism for ocean wave monitoring applications that require self-powering.
