A noval transparent triboelectric nanogenerator as electronic skin for real-time breath monitoring

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 mu A under an extrinsic force of 8 N over an interaction area of 4 x 4 cm 2 , achieving a power density up to 306 mW/m 2 . 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.
