A Self-Healing, Transparent, Highly Stretchable Ionic Conductive Hydrogel for Touch Sensor Application |
| 초록 |
Strethcable, wearable, and bio-compatible soft electronic devices has been studied for its potential use in various applications, including prosthetics, soft robotics, and human-machine interfaces. Ionic conductive hydrogels are good candidates for surface-mount technology due to their excellent transparency and small resistance variation under high stretching states. Herein, we introduce a new type of stretchable self-healing and transparent touch sensor using hydrogel comprised of PVA, Borax, and poly(sodiumacrylate, NaAc). The hydrogel exhibits a fast self-healing capability which can restore over 95 % of its initial conductivity within 7 s healing time. Moreover, no external stimuli (such as heat, pH, light, or catalyst) are required. The self-healing touch sensor is able to monitor the position of touch screens. |
