尽管可穿戴电子产品发展迅速，但开发具有优异机械性能的可穿戴能源设备仍面临挑战，更不用说抵抗子弹了。在这项工作中，开发了一种基于Kevlar和环氧树脂的摩擦电纳米发电机（TENG）（KE-TENG）。它不仅可以保护使用者，而且还可以收集和储存冲击能量。有趣的是，撞击信号还可以通过蓝牙模块远程传输，并作为警报器，显示出其在可穿戴防护服中的潜力。环氧树脂不仅提高了科腾的摩擦电性能，而且大大增强了冲击下的坚固性。此外，在这项工作中，纤维状超级电容器（F-SC）已被制备。F-SC具有稳定的储能容量，在不同弯曲角度或多次充放电循环下不会劣化。最重要的是，它可以与KE-TENGvia整流器组装，实现能量收集和存储的集成系统。
Despite the rapid advances in wearable electronics, there are still challenges in developing wearable energy devices with excellent mechanical properties, let alone resisting bullets. In this work, a triboelectric nanogenerator (TENG) based on Kevlar and epoxy is developed (KE-TENG). It not only can protect users, but also collects the impact energy and store. Interestingly, impact signals can also be transmitted remotelyviaBluetooth module and act as an alarm, showing its potential in wearable protective clothing. Epoxy not only improves the triboelectric properties of KE-TENG, but also greatly enhances the robustness under impact. Furthermore, a fiber shaped supercapacitor (F-SC) has been prepared in this work. F-SC has stable energy storage capacity, which does not deteriorate under different bending angles or multiple charge–discharge cycles. Most importantly, it can be assembled with KE-TENGviarectifiers, realizing an integrated system for energy collection and storage.
