Abstract

The failure of mechanical or electronic equipment caused by high temperature brings huge economic losses. At the same time, the potential fire danger brought by high temperature threatens people's lives. Realizing high temperature alarm is a double test of the material preparation and device construction. Here, a novel self-powered high temperature alarm sensor has been realized based on the combination of triboelectric nanogenerator and bimetallic strip. Besides, electrospun polyimide (PI) nanofiber membranes were prepared as the high temperature resistant friction material. When encountering high temperature, the rapid deformation of bimetallic strip can make it interact with the PI friction material to generate electrical signals for alarm. Finally, a series of demonstrations showed the wide application potential of the system in high temperature alarm.
