Core body temperature monitoring for wearable and med-tech applications

The core body temperature (CBT) is an important parameter for accurate assessments of the human body’s state of health. With greenTEG's technology it is possible to measure the core body temperature non-invasively. Core body temperature data helps drawing conclusion about:


Training level

Sleep quality

Stress & burnout






Heat stroke

In these and other applications it is crucial to get reliable data of the core body temperature. Most of today’s measurement concepts use only temperature sensors for this task. These methods give a good approximation, but cannot measure the core temperature directly (unless via invasive methods in the human body). The following section outlines a potentially more accurate method for measuring CBT using gSKIN® Heat Flux Sensors and temperature sensors.


Advantages of gSKIN® Heat Flux Sensors

  • Small heat flux sensor with high sensitivity, easily integrate into application setups

  • Non-invasive measurement technique for core body temperature measurement

  • Easy to mount on the skin, does not disturb the exercise routine or working habits

  • Possibilty to be integrated with an easy read out software which allows for in-depth analysis

A compact, non-invasive solution for continuous and accurate core body temperature measurement 

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

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

  • Integration solution into any wearable in contact with skin
  • Algorithm to determine body temperature for low activity
  • SMD mountable 2mm x 2mm XU sensor
