Abstract
A hearing aid includes a magnetostrictive electroactive (ME) sensor that generates an electrical signal in response to a magnetic field or a mechanical pressure. In various embodiments, the ME sensor is used for cordless charging of a rechargeable battery in the hearing aid by generating an electrical signal in response to a magnetic field generated for power transfer, magnetic sound signal reception, and/or detection of user commands by sensing a magnetic field or a pressure applied to the hearing aid.
