Recently, the research team of School of Physics and Engineering, headed by Prof. Shan Chongxin and Prof. Dong Lin, made new progress in the field of self-powered flexible electronics, and successfully developed a fully transparent and stretchable AC electroluminescent device that can be driven by triboelectric nanogenerators. The achievement is of great significance in electronic skin, human-machine interface, self-energy sensing and other application fields. It has been published in the international authoritative journal Nano Energy. Joint first authors are postgraduates Wang Xianchuan and Sun Junlu, and joint corresponding authors are Prof. Dong Lin, Researcher Wang Jizheng and Prof. Shan Chongxin. The work was supported by the National Natural Science Foundation of China and ZZU Physics Discipline Enhancement Program.（translator Yang Qiuqiu）
