Wearable electronics have attracted the interest. In this situation, stretchable, self-healable, biocompatible, long-term, and thermal stability are required. Gel has the intrinsic stretchability, transparency, long-term stability, and self-healing ability due to the reversible crosslinking of polymer. Common hydrogel with ion has ions inside the polymer matrix. So, phase separation occurs under the high temperature. Here, hydrogels that consist of the monomer with ion side chain and the monomer affecting elasticity are polymerized. These ionic conductors have intrinsic stretchability (2636%), self-healing (98.3% 3hr), thermal stability up to 100℃, and water-soluble precess due to the ionic bond by an ionic side chain. Using ionic conductors with these properties, thermal sensors and actuators are fabricated. These devices are stable up to high temperature, and maintain the initial performance under the repeating bending, stretching, and after the cutting by external stress. |
