Lightweight and Mechanically Robust Cellulosic Triboelectric Materials for Wearable Self-Powered Rehabilitation Training

Lightweight and robust self-powered wearable devices are of great importance in rehabilitation and medical assistance, but this places greater demands on the development of functional materials. In particular, a balance between reducing the weight of materials and enhancing their mechanical performance is urgently needed. Here, this study reports a design strategy based on a cross-scale strengthening mechanism, which endows triboelectric materials with mechanically robust properties, and can withstand more than 16,600 times its weight without any deformation. A biomimetic ordered network structure with "wall-septum" is obtained by using the directional ice templating method, followed by the formation of more…
