Wearable heaters have been increasingly attracting researchers' great interest due to their efficient utility in maintaining warmth and thermotherapy. Nowadays carbon nanomaterials metallic nanowires tend become the mainstream heating elements wearable considering excellent electrical mechanical properties. Though considerable progress has made, there still exist challenging issues that need be addressed practical applications, including bad breathability poor endurance deformations. Here, we devise a copper nanowire based composite fiber with unique hierarchical structure. This possesses not only performance, but also fantastic tolerance impact, such as bending, twisting, stretching. We further weave these fibers into fabric realize smart personal management through an Android phone by integrating microcontroller unit. Two applications are demonstrated kneepad for articular thermotherapy coat on infant model warmth.
