Abstract
近年来, 离子类皮肤传感器因其高性能和良好的兼容性等优点 而备受关注. 然而, 开发一种多功能、稳定、高灵敏度和耐用的离子类 皮肤传感器仍面临挑战. 本文通过简单的紫外引发聚合制备了具有良 好耐用性、环境(抗冻、耐真空)稳定性、离子导电性、自愈性、高粘 附性和拉伸性的复合离子凝胶. 该离子凝胶可以组装为应变、压力和 温度传感器, 用于检测外部环境的变化. 无论是作为应变传感器还是压 力传感器, 离子凝胶基传感器都具有高灵敏度(GF = 14.7)、宽响应范 围(1%–1600%)、快速响应时间(95.8 ms)、优异的稳定性和可重复性 (1000次). 因此, 它不仅可以追踪关节运动, 还可以监测细微的表情变化 (皱眉). 该离子凝胶还可以组装成敲击传感器和高精度书写板传感器, 用于信息传递. 此外, 该传感器对温度变化具有较高的灵敏度, 温度感 知范围在0–120°C之间, 且检测阈值较低(0.1°C). 因此, 基于离子凝胶的 传感器有望应用于多功能电子和传感设备.
