Transforming scrap inner tube rubber into a triboelectric energy harvester
Abstract
In today's world, the issues of energy shortages, global warming, and pollution caused by reliance on fossil fuels necessitate a swift shift to cleaner energy sources. Triboelectric nano generators (TENGs) present a good remedy for transforming mechanical energy into electricity. This research centres on transforming cast-off inner tube rubber into a TENG that can collect energy from human motion. In this study, surface roughness was improved by sanding, and cost-effective, easily producible TENGs were created using readily available materials such as room-temperature-vulcanizing silicone (RTV silicone). Key findings reveal that inner tube rubber can successfully be upcycled into high-performing TENGs, with sample S2 being particularly noteworthy for generating over 6 Volts and powering four light-emitting diodes (LEDs). Various resistance experiments highlighted the robust energy production potential of these TENGs. Real-world testing of a sports shoe has revealed that the S2 sample can generate more than 15 V, demonstrating the viability of repurposing waste materials for effective energy harvesting.
