The components in traditional human-machine interaction (HMI) systems are relatively independent, distributed and low-integrated, and the wearing experience is poor when the system adopts wearable electronics for intelligent control. The continuous and stable operation of every part always poses challenges for energy supply. In this work, a triboelectric technology-based all-in-one self-powered HMI system for wireless remote telemetry and the control of intelligent cars is proposed. The dual-network crosslinking hydrogel was synthesized and wrapped with functional layers to fabricate a stretchable fibrous triboelectric nanogenerator (SF-TENG) and a supercapacitor (SF-SC), respectively. A self-charging power unit containing woven SF-TENGs, SF-SCs, and a power management circuit was exploited to harvest mechanical energy from the human body and provided power for the whole system. A smart glove designed with five SF-TENGs on the dorsum of five fingers acts as a gesture sensor to generate signal permutations. The signals were processed by the microcontroller and then wirelessly transmitted to the intelligent car for remote telemetry and control. This work is of paramount potential for the application of various terminal devices in self-powered HMI systems with high integration for wearable electronics.
传统人机交互（HMI）系统中的组件相对独立、分散且集成度低，当系统采用可穿戴电子设备进行智能控制时，佩戴体验较差。每个部件的持续稳定运行总是给能量供应带来挑战。在这项工作中，提出了一种基于摩擦电技术的一体化自供电HMI系统，用于无线遥测和智能汽车控制。合成了双网络交联水凝胶并用功能层包裹，分别制备了可拉伸纤维摩擦电纳米发电机（SF-TENG）和超级电容器（SF-SC）。利用包含编织SF-TENG、SF-SC和电源管理电路的自充电电源单元从人体收集机械能，并为整个系统供电。在五个手指背部设计有五个SF-TENG的智能手套用作手势传感器以生成信号排列。信号由微控制器处理，然后无线传输到智能汽车进行远程遥测和控制。这项工作对于各种终端设备在具有高集成度的可穿戴电子设备自供电HMI系统中的应用具有至关重要的潜力。
