Abstract (en)
[origin: WO2023117852A1] The invention relates to a device for detecting fire or abnormal temperature increases, the device comprising a shape memory component (3) that is able to convert the heat received by a source into mechanical energy (movement and/or shape change), a piezoelectric component (4) that is able to convert the mechanical energy into electrical energy, and an electronic module (5) that is able to convert the electrical energy into a radio signal. The shape memory component has, when it moves and/or changes shape, a means (31) for sectioning a support (6) to which the piezoelectric component is secured, the sectioning of the support allowing the piezoelectric component to transition from a first, "tensioned" position (71) to a second, "released" position (72) in which the piezoelectric component (4) is able to resonate and produce electrical energy.
