Core Body Temperature Sensing for Wearable and Med-Tech Applications

Core body temperature is an important vital parameter to determine the health status of a person. greenTEG offers the world’s first sensor for non-invasive and continuous core body temperature sensing. The miniaturized sensor is ideal for the integration into wearable and med-tech devices with skin contact.

New For your evaluation studies, we now offer a patch for wireless core body temperature monitoring. Conact us for additional information.

Early Detection of Health-Related Issues

Many significant health issues leave traces in a person’s natural day-night temperature cycle, also known as circadian cycle. The simplest way to monitor the circadian cycle is to measure CBT. With greenTEG's sensor, CBT can be measured easily and without having a significant impact on the daily routines of the subject. Changes in the circadian cycle, measured via CBT, can help drawing conclusions about the following health issues: jetlag, narcolepsi, insomnia, sleep quality, burnout, Alzheimer's, Parkinson's, ovulation status and others.

Technical Information


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.

Advantages of greenTEG's measurement approach:

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