1. A thermometric device, comprising:

  • a probe, comprising;

    a membrane configured to be applied to an external surface of a body of a subject; and

    one or more temperature sensors located within the probe in thermal contact with the membrane; and

    a processing unit configured to receive a plurality of temperature readings from the one or more temperature sensors, to determine time-dependent parameters of temperature change responsively to the plurality of temperature readings, to calculate, a deep tissue temperature of the body at a location under the skin that is a source of heat conducted to the one or more temperature sensors, and to calculate a core body temperature by correcting for a difference between the core body temperature and the deep tissue temperature.
