A Self-Healing Electronic Sensor Based on Thermal-Sensitive Fluids.

A combination of liquid sensing materials and self-healing polymers is conceived for preparing electronic sensors that can be mended when they suffer damage. The leakage of ionic liquids at a breaking state is avoided with the help of the capillary effect. Photothermal conversion and magnetic-thermal conversion extend the sensing application. The successful development of self-healing sensors is promising for exploiting high-level electronic devices with long-term service.
