Stretchable and wearable WO3 electrochromic devices on silver nanowire (AgNW) elastic conductors are reported. The stretchable devices are mechanically robust and can be stretched, twisted, folded, and crumpled without performance failure. Fast coloration (1 s) and bleaching (4 s) time and good cyclic stability (81% retention after 100 cycles) were achieved at relaxed state. Proper functioning at stretched state (50% strain) was also demonstrated. The electrochromic devices were successfully implanted onto textile substrates for potential wearable applications. As most existing electrochromic devices are based on rigid technologies, the innovative devices in their soft form hold the promise for next-generation electronics such as stretchable, wearable, and implantable display applications.
报道了一种在银纳米线（AgNW）弹性导体上的可拉伸和可穿戴 WO3 电致变色器件。这些可拉伸器件具有机械鲁棒性，可以拉伸、扭曲、折叠和起皱而不会出现性能故障。在松弛状态下实现了快速着色（1 秒）和褪色（4 秒）时间以及良好的循环稳定性（100 次循环后保留 81%）。还证明了在拉伸状态（50%应变）下的正常运行。电致变色器件已成功植入纺织基底，用于潜在的可穿戴应用。由于大多数现有的电致变色器件基于刚性技术，因此这种新型柔软形式的器件有望应用于下一代电子产品，如可拉伸、可穿戴和可植入显示应用。
