TEMPERATURE SENSOR TO MEASURE BODY TEMPERATURE Russian patent published in 2014 - IPC A61B5/01 G01K13/00 G01K7/16 

FIELD: measurement equipment.

SUBSTANCE: invention relates to the field of thermometry and may be used to measure body temperature. A temperature sensor is made of several layers, where the first layer has a central heating element built into it. The second layer fixed with the first one has at least one first thermistor built into it to measure the first temperature value. The third layer comprises at least one second thermistor, built into it, separated from the first thermistor, for measurement of at least one second temperature value. This third layer is adapted to be in contact with body skin to conduct heat emitted from the body through the specified layers. The difference between the first and second temperature values mean heat flow from the body. Heat emitted by the central heating element is adjusted oppositely to the heat flow to achieve the zero heat flow, where the temperature in at least one second thermistor at zero heat flow specifies the body temperature value. These layers are layers of fabric.

EFFECT: improved accuracy of body temperature measurement.
