Recently, stretchable materials have attracted interest due to fabrications of wearable electronics devices. Wearable devices were required biocompatible property as well as a stretchable property. Hydrogels have been received attention as very suitable materials in stretchable and biocompatible properties, simultaneously. However, previous chemical cross-linked hydrogel required complex process. In addition, electrical properties gradually lose in thermal stress, which is attributed to a phase separation between mobile ion and polymers. Here, we synthesized a series of hydrogels with ionic side chains. These hydrogels which are composed of harmless components are biocompatible property. Furthermore, the hydrogels exhibited thermal stability in harsh condition, stretchable (2636%) and self-healing in 3hr. Therefore, these versatile hydrogels were applied in stretchable thermal sensors. These thermal sensors nearly maintained an initial performance under various deformation. |
