Flexible sensors have attracted extensive research interest due to their great application potential in biodetection, flexible display, and wearable devices. However, they still have a lot of room for improvement in terms of luminous color, flexibility, and self-powered systems. A wearable, antifreeze, and discoloration sensing system based on electroluminescence, mechanoluminescence, and tribo-power generation is developed in this paper. Triboelectric nanogenerator systems can harvest biomechanical energy from hand clapping and knee/elbow bending to generate real-time electrical signals. The use of dielectric materials reduces the initial voltage and frequency of light-emitting devices, enabling them to be driven by Triboelectric nanogenerators. At the same time, the device can produce red, blue, white, and other multicolor light. In addition, the system can produce an optical signal output due to external mechanical stimulation. As a result, the sensor system is simple to manufacture and unique to operate, proving its potential applications in areas such as cold-resistant displays, wearable optoelectronics, soft robotics, and electronic skin.

基于柔性水凝胶的高级多模系统的电致发光、机械发光和摩擦电，用于人体运动传感

柔性传感器因其在生物检测、柔性显示和可穿戴设备等方面的巨大应用潜力而引起了广泛的研究兴趣。不过，它们在发光颜色、灵活性和自供电系统方面仍有很大的改进空间。本文开发了一种基于电致发光、机械发光和摩擦发电的可穿戴、防冻和变色传感系统。摩擦纳米发电机系统可以从拍手和弯曲膝盖/肘部收集生物力学能量，以生成实时电信号。介电材料的使用降低了发光器件的初始电压和频率，使其能够由摩擦纳米发电机驱动。同时，该装置可以产生红、蓝、白等多色光。此外，该系统还可以因外部机械刺激而产生光信号输出。因此，该传感器系统制造简单、操作独特，证明了其在耐寒显示器、可穿戴光电、软机器人和电子皮肤等领域的潜在应用。
