Ultrasensitive and reliable conductive hydrogels are significant in the construction of human–machine twinning systems. However, in extremely cold environments, freezing severely limits the application of hydrogel-based sensors. Herein, building on biomimetics, a zwitterionic hydrogel was elaborated for human–machine interaction employing multichemical bonding synergies and experimental signal analyses. The covalent bonds, hydrogen bonds, and electrostatic interactions construct a dense double network structure favorable for stress dispersion and hydrogen bond regeneration. In particular, zwitterions and ionic conductors maintained excellent strain response (99 ms) and electrical sensitivity (gauge factor = 14.52) in the dense hydrogel structure while immobilizing water molecules to enhance the weather resistance (−68 °C). Inspired by the high sensitivity, zwitterionic hydrogel-based strain sensors and remote-control gloves were designed by analyzing the experimental signals, demonstrating promising potential applications within specialized flexible materials and human–machine symbiotic systems.

用于运动监测和人机交互的防冻超灵敏两性离子甜菜碱水凝胶应变传感器
超灵敏且可靠的导电水凝胶对于构建人机孪生系统具有重要意义。然而，在极冷的环境中，冻结严重限制了基于水凝胶的传感器的应用。在此，基于仿生学，利用多化学键合协同作用和实验信号分析，精心设计了一种用于人机交互的两性离子水凝胶。共价键、氢键和静电相互作用构建了致密的双网络结构，有利于应力分散和氢键再生。特别是，两性离子和离子导体在致密水凝胶结构中保持优异的应变响应（99 ms）和电灵敏度（规范因子= 14.52），同时固定水分子以增强耐候性（-68°C）。受高灵敏度的启发，通过分析实验信号设计了基于两性离子水凝胶的应变传感器和遥控手套，展示了在专用柔性材料和人机共生系统中的潜在应用前景。
