Abstract
AbstractFlexible 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.
