Patent ID: 10866147

Abstract:
The invention describes a passive heat-flow sensor (1) comprising a contact face (11) for placement on a subject (8) during a temperature monitoring procedure; and a plurality of combined thermistor arrangements, wherein a combined thermistor arrangement comprises an inner thermistor (S1) arranged at an inner face of the sensor (1); an upper thermistor (S2) arranged at the upper surface of the sensor (1) and arranged relative to the inner thermistor (S1) to measure a vertical heat flow outward from the subject (8); and a lateral thermistor (S3) arranged relative to the inner thermistor (S1) to measure a horizontal heat flow along the contact face (11). The invention further describes a method of measuring the temperature of a subject (8) using a heat-flow sensor (1); and a temperature sensing arrangement (10) for monitoring the temperature of a subject (8) using a heat-flow sensor (1).
