摘要
Triboelectric nanogenerator(TENG) is an efficient way to convert ambient mechanical energy into electricity to power up portable electronics.In this work,a flexible infrared electrochromical device(IR-ECD)with stable performances was assembled with a TENG for building self-powered infrared detector with tunable intensity.As driven by TENG,the electrochromic device could be operated in the mid-IR region due to the reversible electrochromic reactions.An average infrared reflectance contrast of 46% was achieved in 8–14 lm regions and as well a clear thermal image change can be observed.This work indicates that the TENG-driven infrared electrochromical device has potential for use in self-powered camouflage and thermal control.
Triboelectric nanogenerator （TENG） is an efficient way to convert ambient mechanical energy into electricity to power up portable electronics. In this work, a flexible inflared electrochromical device （IR-ECD） with stable performances was assembled with a TENG for building self-powered infrared detector with tunable intensity. As driven by TENG, the electrochromic device could be operated in the mid-lR region due to the reversible electrochromic reactions. An average infrared reflectance contrast of 46% was achieved in 8-14 μm regions and as well a clear thermal image change can be observed. This work indicates that the TENG-driven infrared electrochromical device has potential for use in self-powered camouflage and tbermal control.
