Abstract

The conversion of kinetic energy into light emission can produce real-time self-powered luminescence. In this work, high-intensity triboelectrification-induced electroluminescence (TIEL) is obtained from microsized contacts that have relative sliding motion. The microsized structure significantly promotes the changing rate of the electric field within a luminescent layer. As a result, the produced luminescence intensity is enhanced by two folds compared with a plain-surface contact. Besides, each microsized contact unit acts as a luminescence pixel. A collection of the contacts can be either designed into patterns or arranged into an array. Therefore, the high-intensity TIEL presented can be potentially used in self-powered display and illumination.
