| titleOfInvention | Micropositioning device with multidegrees of freedom for piezoelectric actuators and associated method |
| abstract | The invention relates to a micropositioning device (100) for a piezoelectric actuator (200), the device comprising: means for controlling an electric field applied to said piezoelectric actuator (200) so as to deform the piezoelectric material (201), and means for simultaneous measurement of a variation of electric charge accumulated on the piezoelectric actuator (200) resulting from the deformation; and means for acquiring measurements of the variation of electric charge, for processing these acquisitions and for estimating a displacement (x, y, z) of the piezoelectric actuator (200) and/or an applied force, comprising: a voltage generator connected in parallel to: a divider bridge composed of a first resistor and of a second resistor in series and to a first capacitor connected in series to the piezoelectric actuator, a charge amplifier having a first input connected to a node between the two resistors forming a virtual earth at high floating potential and a second input connected to a node between the first capacitor and the piezoelectric actuator. |
