Heat-Triggered Self-Powered Thermal Cells for Autonomous Fire Sensing and Emergency Power Generation
, and a high specific energy density of 87.7 mAh/g. A prototype of five series-connected ATC units successfully generated a stable 3.15 V output under simulated fire conditions, powering both an LED escape indicator and a wireless smoke alarm. This work offers a feasible way toward self-powered, heat-triggered emergency evacuation system that operate independently of external power grids.
