E-Textiles Network Webinar – Triboelectricity: A Convenient Method to Power the Next Generation of E-Textiles

Presented by Dr Ishara Dharmasena, Loughborough University

Recent advances in Internet of Things (IoT), 5G technology and advanced wearables envision a future in which our living standards are enhanced by being immersed in a digitally connected world. E-textiles are one of the most effective forms in which these technologies can be integrated into our regular activities. Powering E-textiles is a key challenge as batteries are fast becoming obsolete due to rigidity, lack of wearable properties, and the need to recharge. Triboelectric Nanogenerator (TENG), which operate based on the triboelectric effect (static charging) between dissimilar material surfaces, can convert regular body movements into electricity via electrostatic induction. Incidentally, many regular textile polymers are listed in the triboelectric series, signalling their potential as active materials to develop TENGs. This webinar provides an introduction to the TENG technology, especially focussing on their wearable applications. Recent developments in textile based TENGs are discussed, along with their applications in energy harvesting and self-powered active sensing. Furthermore, the integration between the TENGs and textiles will be covered, along with the challenges and prospects of this technology.

This webinar took place on Monday 14th June 1.30pm (BST).
