Abstract
A hearing aid includes an antenna and is powered by one or more signals received by the antenna. At least some of the power for operating the hearing aid is derived from a received signal. Power not used for operation is used for charging a battery, if any, in the hearing aid. The signal can be modulated for one-way communication or there is two-way communication if the hearing aid includes a transmitter coupled to the same antenna or a second antenna.
