A Triboelectric Nanogenerator Based on PDMS and Parafilm For Biomechanical Energy Harvesting

Abstract

In this report, a triboelectric nanogenerator is fabricated using parafilm, polydimethylsiloxane (PDMS) films for the first time. The fabricated TENG has been used for low-frequency mechanical energy harvesting to drive wearable and low-power electronic gadgets. The parafilm and PDMS layers act as triboelectric layers, and packaging aluminium foil acts as conducting electrodes. A flexible TENG with a dimension of 5 x 5 cm2 generated an output voltage ~ 8 V and output power of 20.25 μW at the applied load of 1 MΩ. Further, TENG was explored for switching on several LEDs. The current report presents a simple and cost-effective method for fabricating TENG and can be used for self-powered device applications.
