Fabrication of structured PDMS for triboelectric nanogenerators using 3D printing method and its application

Abstract

Being a highly potential energy harvesting method triboelectric nanogenerators (TENGs) have caught attention of research teams which put emphasis on green energy techniques This cost-effective technology can provide environmental-friendly power sources in the era of energy crisis In this study we fabricate a vertical-contact separation mode triboelectric nanogenerator which triboelectric layer is fabricated by using 3D printed mold Fused Deposition Modeling (FDM) printing technique has been used to manufacture structured mold because of its short low cost fabrication and wider selection of materials By presenting this innovative method we are able to design a complex-structured PDMS triboelectric layer in order to increase contact area and enhance the output performance of TENG Using these triboelectric layers a maximum open-circuit voltage (VOC) short-circuit current (ISC) and power output have been given up to 21 8V 12 75μA and 116μW respectively During stability and durability test its output performance remains stable after 10000 tapping cycles During application test our structured PDMS triboelectric layer is able to light up 30 green LEDs and switch on calculator which proves its self-powered ability for further applications in future
