Eutectogels are emerging as an appealing soft conductor for self-powered sensing and the next generation of flexible human–computer interactive devices owing to their inherent mechanical elasticity and high ionic conductivity. However, it still remains a challenge to simultaneously achieve multi-functional and multi-response integrations through a facile and sustainable approach. Herein, a self-healing, environment tolerant, intrinsically conductive, and recyclable eutectogel with multiple responses is developed via one-step solar-initiated polymerization of deep eutectic solvents (DESs) and ionic liquids (ILs). Abundant hydrogen bonds and ion-dipole interactions impart eutectogels with high mechanical strength (8.8 MPa), ultra-stretchability (>1100%), strong self-adhesion (≈12 MPa), recyclability, and autonomously self-healing ability. Furthermore, the intrinsically conductive eutectogels with appealing versatile sensations on strain, temperature, and humidity can serve as wearable sensors for wireless motion recognition and human–computer interaction control. More importantly, the eutectogel-assembled single-electrode triboelectric nanogenerator (TENG) exhibits extreme environment-tolerant and fast self-healable properties that contribute to maintaining excellent and stable electrical outputs in a wide work temperature range (approximately −40–60 °C), which appear to be promising in self-powered flexible electronics with high environmental adaptability.

多功能和可持续共凝胶的无引发剂太阳能光聚合作为人机界面的多响应和自供电传感器

由于其固有的机械弹性和高离子电导率，Eutectogels 正在成为一种有吸引力的软导体，用于自供电传感和下一代灵活的人机交互设备。然而，通过简便且可持续的方法同时实现多功能和多响应整合仍然是一个挑战。在此，通过低共熔溶剂（DES）和离子液体（IL）的一步太阳能引发聚合，开发了一种具有多种响应的自修复、耐环境、本质导电且可回收的共熔凝胶。丰富的氢键和离子偶极相互作用赋予共析凝胶具有高机械强度（8.8MPa）、超拉伸性（>1100%）、强自粘性（≈12MPa）、可回收性和自主自愈能力。此外，本质导电的共凝胶在应变、温度和湿度方面具有有吸引力的多功能感觉，可以用作无线运动识别和人机交互控制的可穿戴传感器。更重要的是，共凝胶组装的单电极摩擦纳米发电机（TENG）表现出耐极端环境和快速自愈的特性，有助于在较宽的工作温度范围（约-40-60°C）下保持优异且稳定的电输出，这在具有高环境适应性的自供电柔性电子产品中似乎很有前景。
