Title: DEVICE WITH RIGID SHELL DESIGNED TO UNDERGO IMPACTS AND COMPRISING INTERNAL ENERGY RECOVERY MEANS
Abstract:
The device according to the invention comprises an outer rigid shell (12) delimiting a hollow inner volume (14), and comprises: - an inner shell (22) delimiting a hollow inner volume (24), said inner shell (22) being housed in the inner volume (14) of the outer shell (12) and free to move therein, and comprising at least one layer of piezoelectric material (28) able to produce electricity under the effect of an impact that the latter experiences against the outer shell (12); - an electric circuit (32) housed in the inner volume (24) of the inner shell (22), electrically connected to the layer of piezoelectric material (28), and comprising an element for storing the electricity produced by the layer of piezoelectric material (28) of the inner shell (22); and - elements (34) for holding the electric circuit (32) within the inner shell (22).
