Abstract: A self-healing wire includes, an electric wire arranged on a substrate, and a hybrid structure in which the electric wire is covered with at least one fluid selected from the group consisting of a fluid having conductive particles dispersed therein and a fluid having metal ions dissolved therein, formed on a healing portion for a crack to be generated in the electric wire. And a stretchable device includes the self-healing wire formed on a stretchable base material and an electric element mounted only on a base material higher in rigidity than the stretchable base material. Even when a crack is generated in the electric wire due to stretching of the substrate having flexibility, the crack is bridged by the conductive particles or a solid metal deposited from the metal ions in the fluid. Thus the self-healing wire and the stretchable device having both high conductivity and high stretchability are provided.

Abstract translation: 自修复线包括布置在基板上的电线，以及混合结构，其中电线被选自由其中分散有导电粒子的流体和具有金属离子的流体组成的组中的至少一种流体覆盖 溶解在其中，形成在用于在电线中产生的裂纹的愈合部分上。 另外，可拉伸装置包括形成在可拉伸基材上的自修复线，以及只安装在刚性高于伸缩性基材的基材上的电气元件。 即使由于具有柔性的基板的拉伸而在电线中产生裂纹，所以裂纹由导电颗粒或从流体中的金属离子沉积的固体金属桥接。 因此，提供了具有高导电性和高拉伸性的自愈线和可拉伸装置。
