摘要：
A device includes a rigid outer shell defining a hollow inner space. The device also includes an inner shell defining a hollow inner space. The inner shell is housed in the inner space of the outer shell and capable of freely displacing therein and including at least one layer of piezoelectric material capable of generating electric energy under the effect of an impact to which it is submitted against the outer shell. An electric circuit is housed in the inner space of the inner shell, electrically connected to the piezoelectric material layer, and includes an element for storing the electric energy generated by the piezoelectric material layer of the inner shell. Further, the device includes elements for holding the electric circuit in the inner shell.
