Abstract

One easy-make, flexible information storage and display device is prepared. The device show memory effect, which can record the friction trace in real time through the triboelectric effect, and then reproduce the trajectory under the excitation of any kind of polar liquid droplet, completely display the triboelectric area. The explanation mechanism of this phenomenon is proposed, and the main influencing factors of the frictional electrification between solid materials and flexible substrates are determined by systematic experiements. This phenomenon connects mechanoluminescence, electroluminescence, and triboelectrification. It is of great significance to the research of triboelectricity and mechanoluminescence, and is expected to play an important role in display, information storage and encryption.
