Thermal and fire hazards cause significant damage to human life and property. Developing a self-powered thermal and fire hazard sensor is of great importance. This sensor utilizes gravitational potential energy and triboelectric effect to generate electric signals, and has an instantaneous response within the temperature range of 80 to 89 degrees Celsius.
Thermal and Fire hazards result in numerous damage to human life and property. The early detection and instant communication of potential hazards using environmentally sustainable sensors before they occur would signif-icantly reduce the negative impact on the environment while saving lives and property from destruction. Here-in, for the first time, a self-powered thermal and fire hazard sensor was designed by coupling gravitational potential energy to the triboelectric effect to generate electric signals. Harnessing the mechanical integrity and phase change property of the paraffin rod, it is employed as mechanical load support and thermal receptor in the sensor. Furthermore, the sensor was integrated with several communication interfaces such as liquid crystal display (LCD), Wi-Fi emitter, light-emitting diode (LED) light, IoT network, and mobile phone. The sensor exhibited an instant response (similar to 0 s response time) at temperature ranges between 80 and 89 degrees C.
