Technical Information


When working with skin temperature sensors to measure the physiological body temperature, a major challenge is the thermal influences from the environment and physical activity, e.g. leaving a warm building to the cold environment or when clothes or blankets cover the sensor.

Using a heat flux sensor combined with a reference skin temperature sensor allows for compensation of thermal influences from the outside resulting in the real core body temperature signal.

Advantages of greenTEG's measurement approach:

  • Integration solution into any wearable in contact with skin
  • Accurate algorithm to determine body temperature 
  • SMD mountable 2mm x 2mm XU sensor
