Abstract

Patterned displays with self-powered features have been crucial for event-driven information communication and exchange in the Internet of things (IoT) applications. Here, we present a MXene enhanced alternating current electroluminescence (ACEL) device array integrated with the triboelectric nanogenerator (TENG) as the self-powered patterned display. The ACEL device is intrinsically transparent and stretchable. And its emission intensity can be enhanced by 500% through filling 0.25 wt% MXene in the polymer matrix of emission layer, in accordance with the finite element analysis simulation of the electric field strength with various MXene loading. Finally, a patterned ACEL device is constructed and powered with a simple TENG for patterned display. This self-powered patterned ACEL display has considerable potential for applications of human-healthcare monitoring, information-security communication, and human-machine interface in IoT.
