Flexible sensors with skin-like self-healing and sensing properties are now drawing great attention for their prospective application in many promising fields, including electronic skins, wearable electronics and soft robots. However, the unavoidable irregularity external stimuli and repetitive motions usually resulting in function loss. So, the self-healing abilities on both mechanical and electrical characters are highly attractive. Till now, numerous studies have been given to realize the self-healing of mechanical properties, while the repair of electrical properties still remains a great concern. Herein, the current main methods to prepare self-healing flexible sensors are summarized and discussed, consisting of self-healing materials with conductive layers, self-healing materials with embedded conductive network and self-healing ionic conducting hydrogels. Finally, a summary and perspective on future research directions and the potential of each strategy are given.

自修复导电材料和具有所需功能可修复性的柔性传感器的最新进展

具有类皮肤自愈和传感特性的柔性传感器因其在许多有前景的领域的潜在应用而备受关注,包括电子皮肤、可穿戴电子产品和软机器人。然而,不可避免的不规则外部刺激和重复运动通常会导致功能丧失。因此,机械和电气特性的自愈能力非常有吸引力。迄今为止,已经进行了大量的研究来实现机械性能的自愈,而电性能的修复仍然是一个非常值得关注的问题。在此,总结和讨论了目前制备自修复柔性传感器的主要方法,包括具有导电层的自修复材料,具有嵌入导电网络的自修复材料和自修复离子导电水凝胶。最后,对未来的研究方向和每种策略的潜力进行了总结和展望。
