This study presents a novel transparent, sensitive electronic skin (S-TENG) using a frictional nanogenerator for energy harvesting and physiological motion monitoring. Featuring thermally treated PVDF fiber membranes and silver nanowire electrodes, the e-skin boasts 80% transparency, high sensitivity (detecting 0.13 g touch), stability, and breathability. It generates 301 V and 2.7 µA under 8N force, achieving 306 mW/m2 power density. S-TENG holds promise for self-powered wearables and health training applications, representing a significant step in e-skin innovation. [Display omitted] Against the backdrop of advancements in modern multifunctional wearable electronics, there is a growing demand for simple, sustainable, and portable electronic skin (e-skin), posing significant challenges. This study aims to delineate the development of a straightforward, transparent, highly sensitive, and high power-density electronic skin based on a triboelectric nanogenerator(S-TENG), designed for harvesting human body energy and real-time monitoring of the physiological motion status. Our e-skin incorporates thermally treated polyvinylidene fluoride (PVDF) fiber membranes as the contact layer and a film of silver nanowires as the conductive electrodes. The resulting contact-separation type e-skin exhibits an impressive transparency of 80 %, along with a nice sensitivity value, capable of detecting a light touch from a 0.13 g sponge and demonstrating good working stability and breathability. Leveraging the triboelectric effect, our e-skin generates an open-circuit voltage of 301 V and a short-circuit current of 2.7 μA under an extrinsic force of 8 N over an interaction area of 4 × 4 cm2, achieving a power density up to 306 mW/m2. With its signal processing circuitry, the integrated S-TENG showcases nice energy harvesting and signal transmission capabilities. Accordingly, we contend that S-TENG has potential applications in energy capture and real-time human motion state monitoring. This research is anticipated to blaze a novel and practical trail for self-powered wearable devices and personalized health rehabilitation training regimens. [ABSTRACT FROM AUTHOR]
