Dynamic Triboelectrification‐Induced Electroluminescence and its Use in Visualized Sensing

Triboelectrification-induced electroluminescence converts dynamic motion into light emission. Tribocharges resulting from the relative mechanical interactions between two dissimilar materials can abruptly and significantly alter the surrounding electric potential, exciting the electroluminescence of phosphor along the motion trajectory. The position, trajectory, and contour profile of a moving object can be visualized in high resolution, demonstrating applications in sensing.
