CORE was developed by greenTEG, an innovative company based in Zurich, Switzerland.

The goal was very simple: to improve athletes' performance.

To achieve this goal, they have merged three different areas of expertise: sensing technologies, physiological research and sports science.

The result is a wearable device that can accurately monitor core body temperature during sporting activities, but can be used in normal daily life and during illness.

The CORE sensor is a user-friendly and portable sensor. The sensor measures real-time data of the core temperature of the body using the SWISS-Made sensor technology. The CORE sensor is equipped with an innovative sensor that can make thermal energy measurable through the power of an AL algorithm based on more than billion data points. Thanks to the power of machine learning, the CORE sensor can be continuously optimized.
