Dual Conductive Network Hydrogel for a Highly Conductive, Self-Healing, Anti-Freezing, and Non-Drying Strain Sensor

Self-healing hydrogel plays an important role in flexible sensors. However, the development of high-performance hydrogel-based strain sensors with both high sensitivity and large sensing range remains a key challenge. Herein, we prepare a dual conductive network (DCN) hydrogel based on carbon nanotube (CNT) film and conductive hydrogel that exhibits high-conductivity, self-healing, anti-freezing, and non-drying features. The tolerance of this...
