Abstract: An event detection device consumes zero power until an alarming event takes place by taking; advantage of the phase transition of a PCM material (Phase Change Material) to monitor relevant physical/chemical events. If the PCM material is ion-conducting, the device comprises a liquid-activated battery, an ion-conducting PCM material (Phase Change Material), positioned in contact with the liquid-activated battery, and an electronics module, connected to the liquid-activated battery, that powers up with the battery. If the PCM material is a non ion-conducting PCM material, the device additionally comprises a ion- conducting liquid, and being the non ion-conducting PCM material placed as a barrier between the ion-conducting liquid and the liquid-activated battery.
