能够监测生理信号并通过用户和电子设备之间的闭环通信显示反馈信息的电子皮肤设备正在考虑用于下一代可穿戴设备和“物联网”。这样的设备需要超薄，以实现与人体的无缝和保形接触，以适应反复运动带来的压力，并确保穿着舒适。最近，自修复化学推动了可变形和可重构电子器件的重要进展，特别是自修复电极是关键的推动因素。与具有自愈动态特性的聚合物基体不同，被破坏的导电网络在受到损伤后无法恢复其可拉伸性。在这里，我们报道了导电纳米结构与动态交联聚合物网络接触时的自重建观察。这与自修复聚合物的自键特性相结合，可以将互连、传感器和发光器件集成到一个单一的多功能系统中。这是第一个自主的自修复和可拉伸的多组件电子皮肤，为未来强大的电子产品铺平了道路。
Electronic skin devices capable of monitoring physiological signals and displaying feedback information through closed loop communication between the user and electronics are being considered for next-generation wearables and the 'Internet of Things'. Such devices need to be ultrathin to achieve seamless and conformal contact with the human body, to accommodate strains from repeated movement and to be comfortable to wear. Recently, self-healing chemistry has driven important advances in deformable and reconfigurable electronics, particularly with self-healable electrodes as the key enabler. Unlike polymer substrates with self-healable dynamic nature, the disrupted conducting network is unable to recover its stretchability after damage. Here, we report the observation of self-reconstruction of conducting nanostructures when in contact with a dynamically crosslinked polymer network. This, combined with the self-bonding property of self-healing polymer, allowed subsequent heterogeneous multi-component device integration of interconnects, sensors and light-emitting devices into a single multi-functional system. This first autonomous self-healable and stretchable multi-component electronic skin paves the way for future robust electronics.
