Abstract
A hearing aid that automatically turns on when placed in an ear. In one embodiment, the hearing aid has a pair of electrodes that are coupled to a hearing circuit and a power source. Placing the electrodes in contact with an ear closes a circuit between the power source and the hearing circuit so that power is provided to the circuit. The circuit is opened and power is terminated from the hearing circuit when the hearing aid is removed from the ear. In another embodiment, the hearing aid includes a temperature sensor that is coupled to the hearing circuit and the power source. Power is provided to the hearing circuit when the hearing aid is placed within an ear and the temperature sensor senses the body temperature of the user. In yet another embodiment, the hearing aid includes a contact sensor that closes a circuit between the hearing circuit and the power source when the hearing aid is placed within an ear.
