  • Zero heat flux temperature sensing device
    Patent number: 8845187
    Abstract: The invention relates to a zero heat flux temperature sensing device (100) for sensing a core body temperature of an object (113). The zero heat flux temperature sensing device (100) comprises a layer (107), a first temperature gradient sensor (105), a first heat flux modulator (103) and a heat flux modulator controller (102). The layer (107) has an opposing first side (112) and second side (108). In use the first side (112) is nearest to the object (113). The layer (107) is for obtaining a first temperature difference over the layer (107) in response to a first heat flux in a first direction from the first side (112) to the second side (108). The first temperature gradient sensor (105) senses at the first side (112) of the layer (107) a second temperature difference in a second direction. The second direction extends from a first border of the first side (112) towards a second border of the first side (112).
