Skin-like field-effect transistors are key elements of bio-integrated devices for future user-interactive electronic-skin applications. Despite recent rapid developments in skin-like stretchable transistors, imparting self-healing ability while maintaining necessary electrical performance to these transistors remains a challenge. Herein, we describe a stretchable polymer transistor capable of autonomous self-healing. The active material consists of a blend of an electrically insulating supramolecular polymer with either semiconducting polymers or vapor-deposited metal nanoclusters. A key feature is to employ the same supramolecular self-healing polymer matrix for all active layers, i.e., conductor/semiconductor/dielectric layers, in the skin-like transistor. This provides adhesion and intimate contact between layers, which facilitates effective charge injection and transport under strain after self-healing. Finally, we fabricate skin-like self-healing circuits, including NAND and NOR gates and inverters, both of which are critical components of arithmetic logic units. This work greatly advances practical self-healing skin electronics.

类皮肤场效应晶体管是未来用户交互式电子皮肤应用的生物集成设备的关键元件。尽管最近在类皮可拉伸晶体管方面取得了快速发展，但在保持这些晶体管必要的电气性能的同时赋予自愈能力仍然是一个挑战。在这里，我们描述了一种能够自主自愈的可拉伸聚合物晶体管。活性材料由电绝缘超分子聚合物与半导体聚合物或气相沉积金属纳米簇的混合物组成。一个关键特征是对类皮晶体管中的所有有源层（即导体/半导体/介电层）采用相同的超分子自修复聚合物基质。这提供了层之间的粘附和紧密接触，有利于自修复后在应变下有效的电荷注入和传输。最后，我们制造了类皮肤的自愈电路，包括与非门、或非门和反相器，它们都是算术逻辑单元的关键组件。这项工作极大地推进了实用的自愈皮肤电子学的发展。
