Recent progress of triboelectrification-induced electroluminescence: from fundaments to applications

Abstract Luminescence is the premise for humans and even all creatures in the world to survive, as well as a crucial means for humans to interact with the environment. Recently, triboelectrification-induced electroluminescence (TIEL) has been applied in anti-counterfeiting, real-time vision sensor, human/machine interactive system, as well as self-powered illumination and display, thus attracting significant attention. It can convert kinetic energy into light through the coupling effects of triboelectrification and electroluminescence. In this review, we focus on the latest advancements of TIEL, including its fundaments, novel applications, and outlook. It is predicted that TIEL will be widely applied in daily activities and industrial productions, so as to achieve self-powered smart systems.
