Intrabody communication for a hearing aid

A method, comprising:

• operating a hearing aid including a first component and a second component, the first component including a first pair of electrodes and the second component including a second pair of electrodes;
• electrically engaging the first pair of electrodes and the second pair of electrodes with skin;
• and
• transmitting an electrical signal from the first component to the second component by electrical conduction along the skin between the first pair of electrodes and the second pair of electrodes during said engaging.

A method, comprising:

• providing a hearing aid including a first component and a second component, the first component including an acoustic sensor;
• contacting skin with the first component and the second component;
• and
• transmitting an electrical signal from the first component to the second component during said contacting by electrical conduction along a pathway formed by the skin between the first component and second component.

A system comprising:

• a hearing aid to enhance hearing of a user, the hearing aid including:
• a first component operable for placement in contact with skin of the user, the first component including a first pair of electrodes operable to be electrically coupled to the skin and a transmitter circuit operable to transmit electrical signals to the skin through said first pair of electrodes;
• and
• a second component spaced apart from said first component, said second component being sized for placement in a passageway of an ear of the user, the second component including a receiver circuit to receive said electrical signals by electric conduction along the skin from said first component and an output device responsive to said electrical signals to stimulate hearing of the user.

A method, comprising:

• operating a hearing aid including a first component and a second component, the first component including a first pair of electrodes and the second component including a second pair of electrodes;
• placing the first component to electrically couple the first pair of electrodes to skin of a first ear of a user;
• placing the second component to electrically couple the second pair of electrodes to skin of a second ear of the user;
• generating an electric potential between the first pair of electrodes to transmit a first electrical communication signal from the first component through the skin of the first ear of the user;
• and
• receiving the first electrical communication signal through the skin of the second ear with the second component over a transmission pathway between the first component and second component.
