Triboelectric Nanogenerator (TENG) is capable of efficiently capturing mechanical energy and transforming it into electrical for self-powered systems, making an ideal power source Polymer Dispersed Liquid Crystal (PDLC). Herein, a Self-powered Intelligent Attenuator (SPILCA) demonstrated metasurface real-time modulating. The convergent beam-shaping consisting holey meta-atoms with diameters ranging from 100 nm to 300 fabricated by e-beam lithography (EBL). While the unique optical characteristics can be modulated within certain frequency range, E7 (E7-LC) has large index birefringence, powered TENG switch between two response states. Therefore, combination SPILCA achieve control using electricity regulatory LC electromagnetic metasurface. In order build this modulating, vertically contact-separated based on Nylon electrospun film as triboelectric material proposed. maximum values open-circuit voltage, short-circuit current, transferred charge are 165 V, 25 µA, 86 nC, respectively. By measuring testing modulation effect metasurface, seen that good signal, even reach 96% intensity when laser wavelength 450 current 0.09 A. This photoelectric device does not require additional supply, great potential in future smart system design.
