Abstract
AbstractAnti‐counterfeiting and visual optical information encryption/decryption technology have attracted widespread attention in the field of information security. Luminescent encryption technologies still face a huge challenge in external high voltage power supply, complex architecture, and expensive decryption equipment, which hinder their broad applications. Herein, a wearable integrated self‐powered electroluminescent (EL) display device (W‐ELD) that consists of MXene/Silicone‐based triboelectric nanogenerator (MS‐TENG) and EL device based on a shared MXene electrode is developed for patterned display and information encryption. The W‐ELD features an all‐in‐one MXene electrode with excellent flexibility and high conductivity of 0.6 kΩ sq−1, which is shared by both MS‐TENG and EL devices. The MS‐TENG demonstrates excellent output performances (output power of 0.9 Wm−2) and high stability and durability (104 cycles), which can directly light up the flexible patterned EL device. More importantly, when dripping conductive electrolyte solution, the W‐ELD based on “中國”‐patterned MXene electrode can precisely reveal the encryption information through self‐powered EL emission for real‐time visualized information interaction. Consequently, the all‐in‐one MXene electrode‐based W‐ELD that integrates both MS‐TENG and EL device demonstrates exceptional patterned EL‐based information encryption features, which offers a potential prospect in wearable self‐powered optoelectronic devices, flexible displays, and encryption technology.
