Abstract:
1. A zero heat flux temperature sensing device for sensing a core body temperature of an object wherein the zero heat flux temperature sensing device comprises: a layer having an opposing first side and second side, wherein, in use, the first side is nearest to the object, and the layer is for obtaining a first temperature difference over the layer in response to a first heat flux in a first direction from the first side to the second side, a first temperature gradient sensor for sensing at the first side of the layer a second temperature difference in a second direction, the second direction extends from a first border of the first side towards a second border of the first side, a first heat flux modulator, arranged at the first side of the layer and being constructed for changing a second heat flux in the second direction at the first side of the layer to influence the second temperature difference, and a heat flux modulator controller for controlling the first heat flux modulator based on the sensed second temperature difference in order to decrease an absolute value of the second temperature difference.
