Self-Repairing User Interface Architecture for Sustainable Interactive Systems

This study investigates a self-healing user interface system that supports continuous touch operation after physical damage. The system combines mechanical recovery materials with built-in signal repair circuits. A total of 24 tactile panel samples were tested under the same environmental conditions. The self-healing samples recovered more than 95% of their original touch sensitivity within three minutes after damage, while the control samples recovered only about 70%. Signal output remained stable, with less than ±3% variation from baseline. In repeated use tests, the self-healing group operated for more than 6000 touch cycles, showing a 40% increase in lifespan compared to the control group. These results show that integrating self-repair into user interfaces can extend working life and reduce function loss during long-term use. The method is suitable for touchscreen devices used in high-contact environments. However, additional studies are needed to examine outdoor performance, long-term wear, and system compatibility with existing hardware.
