CORE is the first non-invasive wearable that allows for continuous core body temperature measurements under real-life conditions with great accuracy


Accurate technology

Our patented novel sensor allows to accurately monitor core body temperature just through skin contact.

Artificial Intelligence Algorithm

CORE uses a machine learning based algorithm to calculate and analyze core body temperature in real-time.

Comfortable and lightweight

The device is easily mounted on a chest strap or attached with a medical grade patch. It is water-resistant and can be sanitized using alcohol.




Connect with your device(s)

CORE connects wirelessly with Garmin, iOS and Android smartwatches and smartphones.

Constant monitoring

Long battery life allows monitoring core body temperature for longer periods (over 6 days) without interruption.

BLE compatible

Multiple patches can be operated with the same smartphone. The BLE standard temperature profile allows to stream the data on any BLE compatible device.
