What is the CORE sensor?

The CORE sensor is a compact, wearable device that delivers highly accurate and continous core body temperature measurement data.

Positioned on the torso, usually on a heart rate monitor strap or with medical-grade adhesive patches, the CORE sensor measures 'thermal energy transfer' to calculate your real-time core body temperature.

You can view your live core body temperature data and save it with the CORE App or with many popular sport computers and watches including as Garmin, Wahoo, COROS, Apple watches and more.

The CORE sensor is rechargeable and waterproof and made from medical grade plastic that is anti-allergic and gentle against the skin.

Why is your core body temperature important?

Your core body temperature is individual to you. Knowing your own internal temperature helps you to monitor your well-being 24/7 and track your circadian rhythm or fertility in women.

During sporting activity, when you get hot, your performance drops. The insights delivered by your CORE sensor can help you optimise your training and racing. Set alerts to warn you to cool down and avoid overheating and use your data to train and condition your body and enable you to take make smarter decision so you can race better.

How does core body temperature relate to sporting performance?

This video provides an overview how core body temperature relates power output and and how the CORE sensor can be used in sports.

How to use the CORE sensor

After setting up the CORE sensor once, it automatically connects to your paired devices. Just keep it charged, and shake it to check for the blinking green light... you are now ready to go. That's it.

The CORE sensor stores your core body temperature data onboard for 2 days and via the CORE App and the CORE Cloud you can view current and historical data.

You can use the CORE App and a host of compatible devices and services to view live data and to store and analyse your data.

Take a look at setting up and using the CORE sensor.
