柔软的可变形电子设备提供了监测生理信息和健康状况以进行疾病诊断的手段。然而，它们的实际效用是有限的，由于缺乏本质的热开关的机械改造的适应性和自我修复能力，对机械损伤。在这里，报告了基于超支化聚合物和双相液态金属的自修复、可重构、热开关器件平台的设计概念、材料和物理、制造方法以及应用机会。前者为皮肤开关提供了出色的自愈性能和独特的可调刚度和可由温度调节的粘附力，而后者则使液体金属电路具有极高的拉伸性（> 900%）和高导电性（3.40 × 104S cm − 1），以及简单的回收能力。由皮肤表面的温度升高触发，多功能设备平台可以方便地贴合并牢固地粘附到分层纹理化的皮肤表面，实现无创、连续、舒适的健康监测。此外，自修复和粘合特性允许多个多功能电路组件组装并完全包裹在3D曲线表面上。总之，自愈、变革和自组装电子产品的设计、制造和概念验证为强大的软变形设备、智能机器人、假肢和物联网以及不规则表面上的人机界面开辟了新的机会。
Soft, deformable electronic devices provide the means to monitor physiological information and health conditions for disease diagnostics. However, their practical utility is limited due to the lack of intrinsical thermal switching for mechanically transformative adaptability and self‐healing capability against mechanical damages. Here, the design concepts, materials and physics, manufacturing approaches, and application opportunities of self‐healing, reconfigurable, thermal‐switching device platforms based on hyperbranched polymers and biphasic liquid metal are reported. The former provides excellent self‐healing performance and unique tunable stiffness and adhesion regulated by temperature for the on‐skin switch, whereas the latter results in liquid metal circuits with extreme stretchability (>900%) and high conductivity (3.40 × 104S cm−1), as well as simple recycling capability. Triggered by the increased temperature from the skin surface, a multifunctional device platform can conveniently conform and strongly adhere to the hierarchically textured skin surface for non‐invasive, continuous, comfortable health monitoring. Additionally, the self‐healing and adhesive characteristics allow multiple multifunctional circuit components to assemble and completely wrap on 3D curvilinear surfaces. Together, the design, manufacturing, and proof‐of‐concept demonstration of the self‐healing, transformative, and self‐assembled electronics open up new opportunities for robust soft deformable devices, smart robotics, prosthetics, and Internet‐of‐Things, and human–machine interfaces on irregular surfaces.
