  • Method for compensating the position offset of a capacitive inertial sensor, and capacitive inertial sensor
    Patent number: 6546799
    Abstract: An inertial sensor having a stator and a rotor made of semiconductor material and electrostatically coupled together, and a microactuator also made of semiconductor material, coupled to the rotor and controlled so as to move the rotor itself and thus compensate for the position offset thereof.

  • Integrated device comprising a semiconductor material microactuator, in particular for a hard disk read/write head
    Patent number: 6259584
    Abstract: A microactuator comprises an outer stator and an inner rotor electrostatically coupled to a stator. The rotor comprises a suspended mass with a substantially circular shape, and a plurality of mobile arms extending radially towards the exterior, starting from the suspended mass. The stator has a plurality of pairs of fixed arms extending radially to the suspended mass, a respective mobile arm being arranged between each pair of fixed arms. The fixed arms are divided into fixed drive arms connected to a drive stage for actuating the microactuator, and into fixed measure arms connected to a measure stage, and define a capacitive uncoupling structure.
