Process and device for conditioning a piezoelectric element to modify its mechanical properties.

摘要

- Conditioning of piezo electric elements. - The conditioning process according to the invention consists in connecting in parallel, between the two terminals of the piezo electric element: . an ohmic dissipation resistor (R), . and a load impedance (ZL) of the resistive and/or capacitive type, through a negative impedance converter to modify the mechanical properties of the piezo- electric element. - Application to the attenuation of vibrations. <IMAGE>
