A piezoelectric device for generating a voltage, comprising a vibratory blade with a first end secured to a fixed substrate and a second, free end which can be moved by applying a mechanical pulse thereon. At least one separate piezoelectric element is provided on one side of blade in such a way that it is deformed by the oscillation of the blade following the application of said mechanical pulse, and thereby generates a voltage. The device is characterized in that the blade is generally U shaped and has two substantially planar arms joined together via a curved intermediate portion. A first arm is secured to the substrate and a second arm has the free end. |
