Abstract
In one embodiment, a temperature sensing apparatus includes a temperature sensor disposed in a structure at a first depth from a first surface of the structure. A heat flux sensor is also disposed in the structure at substantially the same depth as the first depth. A measurement circuit is coupled to the temperature sensor and the heat flux sensor. The measurement circuit calculates a surface temperature of the first surface based on a temperature of the temperature sensor and a heat flow of the heat flux sensor.
