1. An autonomous impact detection device comprising:
at least one impact detector;
at least one wireless transmission device configured to transmit information collected by the impact detector;
at least one energy storage device configured to supply the impact detector and the wireless transmission device with energy;
a first Seebeck module configured to supply the energy storage device with energy when a temperature gradient is applied thereto, and
a second Seebeck module configured to supply the energy storage device with energy when a temperature gradient is applied thereto, wherein the first Seebeck module is arranged according to a first configuration and wherein the second Seebeck module is arranged according to a second configuration such that, when the autonomous impact detection device is subjected to a temperature gradient, a voltage generated by the first Seebeck module is of opposite sign to a voltage generated by the second Seebeck module.
