Title:
SUBCUTANEOUS PIEZOELECTRIC BONE CONDUCTION HEARING AID ACTUATOR AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2010/142018
Kind Code:
A8
Abstract:
An implantable bone-conduction hearing actuator based on a piezoelectric element, such as a unimorph or bimorph cantilever bender, is described. Unlike other implantable bone conduction hearing actuators, the device is subcutaneous and once implanted is entirely invisible. The device excites bending in bone through a local bending moment rather than the application of a point force as with conventional bone-anchored hearing aids.
