具有自供电功能的图案显示器对于物联网（IoT）应用中事件驱动的信息通信和交换至关重要。在这里，我们提出了一个MXene增强的交流电致发光（ACEL）器件阵列，集成了摩擦电纳米发电机（TENG）作为自供电的图案显示器。ACEL装置本质上是透明和可拉伸的。在发射层聚合物基体中填充0.25 wt%的MXene，可使其发射强度提高500%。最后，构建了一个图像化ACEL装置，并使用一个简单的TENG为图像化显示供电。这种自供电模式ACEL显示器在物联网中的人体健康监测、信息安全通信和人机界面应用方面具有相当大的潜力。
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 selfpowered 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 selfpowered patterned ACEL display has considerable potential for applications of human-healthcare monitoring, information-security communication, and human-machine interface in IoT.
