Inspired by biosystem, ionic hydrogels have been extensively studied as promising materials for wearable or implantable devices. Herein, we report novel ionic hydrogels that comprise dynamically crosslinked polyzwitterion and physically crosslinked polyvinyl alcohol, which demonstrate excellent mechanical properties, repeatable self-adhesion, and high and linear strain sensitivity. The obtained hydrogels can be directly attached to human skin as sensors to detect or monitor physiological signals.
受生物系统的启发，离子水凝胶作为有前途的可穿戴或可植入设备材料得到了广泛研究。在此，我们报告了一种新型离子水凝胶，它由动态交联的聚两性离子和物理交联的聚乙烯醇组成，具有优异的机械性能、可重复的自粘性以及高线性应变灵敏度。所得到的水凝胶可以直接附着在人体皮肤上作为传感器来检测或监测生理信号。
