摘要

Integrating power into fabrics offers exciting opportunities for wearabletechnologies, which has long remained challenging to make flexible,high temperature resistant textile-based powers. Here, an all yarns-basedtriboelectric nanogenerator (Y-TENG) is proposed to harvest electricalenergy and sense biological motion for temperatures between 25 and400 ℃, the upper limit of temperature is greatly improved. The Y-TENGis capable of outputting a transferred charge density of 30 nC cm~(?2), theexternal load resistance is 180 MΩ, and the peak power reaches 0.17 mW,and the average response time is lower than 15 ms. Based on a simpleprocessing strategy, when introducing silica aerogel during electrospinningof polyimide nano-covered layer to make multi-ply and stabilizedtriboelectric yarns. Unlike ordinary fibers and yarns, the core-shellstructured design also shows a high sensitivity to all kinds of mechanicaltriggering sources. Furthermore, a self-powered movement characteristicmonitoring system by coordinating smart protective suit is furtherdeveloped to provide real-time sensing and rescuing assistance. Thisaerogel nano-covered triboelectric yarn has great application prospects forenergy generation and motion detection in high-temperature and manyother high-risk environments.
