1. A mechanical vibration energy recovery electric generator, comprising:
a bistable system capable of taking one or the other of two stable positions with respect to two ends, as a response to an excitation of given orientation (FEXT); at least one monostable oscillating system capable of periodically acting on at least one of the two ends, as a response to said excitation; and a converter of the motion of an element of the bistable system into electric energy; wherein: the monostable oscillating system comprises: first and second arc-shaped blades, in front of each other, each blade being attached by its ends to a rigid support package, the point of attachment of each blade being arranged along a line which is not orthogonal to said orientation (FEXT); and first and second masses, each mass being attached to an intermediate point of one of the blades via a rigid connection which is not parallel to said orientation (FEXT); and the bistable system comprises: a third spring blade in compression between the first and second blades, the bearing points of the third blade on the first and second blades forming said ends, such bearing points being arranged along a line which is not parallel to said orientation (FEXT); and a third mass, attached to the third blade. |
