Abstract
A device for measuring a body temperature includes an earbud configured for insertion into at least a portion of an ear canal of a user to thereby create a substantially sealed ear canal. A temperature sensing element is fixed to the earbud at a location in which the temperature sensing element is thermally coupled to air in the sealed ear canal when the earbud is at least partially inserted into the ear canal. The temperature sensing element has a temperature-dependent electrical characteristic. The temperature sensing element is in electrical communication with a circuit that is configured to determine a temperature of the air in the sealed ear canal of the user in response to the temperature-dependent electrical characteristic.
