Abstract (en)
[origin: WO2011015722A1] The invention relates to a micrometric movement device, comprising a bending piezoelectric actuator (10) connected to a supporting and adjusting structure (20) via a decoupling means (30) including an inertial body (31), a portion of which is attached to the piezoelectric actuator, another portion being attached to a layer (32) secured to the supporting and adjusting structure, said layer being made of a material having a high capacity for absorbing vibrations, and having an energy dissipation factor tan (d) of between 0.5 and 0.7 in a frequency range of 5 to 1000 Hz.
