1. An impact detection device comprising an impact detector, a wireless communication device, an energy storage device, an autonomous electrical energy generation device distinct from the impact detector and comprising a piezoelectric module and a Seebeck module, and a system adapted to receive energy by radio frequency, the impact detection device being configured to adopt the following two modes:
a first autonomous mode, in which the autonomous electrical energy generation device is configured to supply the impact detector and the wireless communication device;
a second external mode, in which the system adapted to receive energy by radio frequency is configured to supply the impact detector and the wireless communication device,
wherein the wireless communication device is configured to receive instructions to indicate to the impact detection device the operating mode to adopt among the two modes.
