“…The combination of rapid and reversible fire warning is important yet remains challenging. 8 In fire accidents, beyond rapid fire detection, real-time monitoring of the actions of firefighters and the operations of firefighting robots is crucial. This monitoring system is designed to collect essential data on both human health metrics and the operational status of equipment.…”

High-temperature affordable flexible polymer-based pressure sensors integrated with repeatable early fire warning service are strongly desired for harsh environmental applications, yet their creation remains challenging. This work proposed an approach for preparing such advanced integrated sensors based on silver nanoparticles and an ammonium polyphosphate (APP)modified laminar-structured bulk wood sponge (APP/Ag@WS). Such integrated sensors demonstrated excellent fire warning performance, including a short response time (minimum of 0.44 s), a long-lasting alarm time (>750 s), and reliable repeatability. Moreover, it achieved high-temperature affordable flexible pressure sensing that exhibited an almost unimpaired working range of 0− 7.5 kPa and a higher sensitivity (in the low-pressure range, maximum to 226.03 kPa −1 ) after fire. The high stability was attributed to reliable structural elasticity, and the wood-derived amorphous carbon is capable of repeatable fire warnings. Finally, a Ag@APP/WS-based wireless fire alarm system that realized reliable house fire accident detection was demonstrated, showing great promise for smart firefighting application.
