  • Abstract
    A micro-machined transducer and sensor for a new implantable audioprosthesis to substitute the human tympanic-ossicular system has been developed. The device is intended to restore hearing by implanting it in patients with a damaged or surgically removed ossicular chain. Different configurations of devices have been analysed. The proposed piezo-actuator has a diameter of 1.0 mm with a total thickness of 3.5 m, which reaches deformations of up 16.8 nm with a typical excitation of 3 V.
