A piezo-device for positioning a load is described. The piezo-device comprises a stator module comprising one or more piezo-electric actuator(s) oriented in a single direction. The stator module furthermore comprises at least one hinge for allowing deformation of the stator module upon actuation of the piezo-electric actuator. The piezo-device also comprises a slider or rotor module, the slider or rotor module being in contact with the stator module in at least three points of contact. The at least one hinge and the one or more piezo-electric actuator(s) are arranged in position with respect to each other for providing a tangential motion of the slider or rotor module upon actuation of the at least one piezo-actuator. The slider or the rotor are driven and supported through the points of contact. |
