In this study, we developed an electrochromic device (ECD) for wearable applications that combines high transparency, high stretchability, and excellent stability. By integrating single-walled carbon nanotube (SWCNT) electrodes with the ruthenium-complex-based electrochromic material Poly-Ruthenium, the device achieved a transmittance of approximately 80% in the bleached state and 62% in the colored state. Furthermore, it operated stably even under 100% strain and maintained robust color-switching performance after 100 operating cycles. These results highlight its potential for future applications in electronic cosmetic devices and other wearable technologies.
