A device for measuring the temperature within a body from a body surface at a different temperature, comprising: a heat shield for application to the body surface, comprising an outer heat-conducting portion (52), and an inner heat-insulating portion (50); a heater or cooler (41) to heat or cool the outer portion (52) of said heat shield to the temperature of the body surface; a first temperature sensor (37) positioned on a surface of the inner heat-insulating portion (50) of the heat shield which is applied to the body surface; a second temperature sensor (38) positioned to measure the temperature of the outer portion (52) of the heat shield; a heater or cooler control circuit to heat or cool the outer portion (52) of the heat shield towards the temperature measured by the first temperature sensor (37); and a second control circuit to forecast the first temperature sensor (37) equilibrium temperature. |
