How does CORE measure your body temperature?

CORE uses a thermal energy transfer sensor from greenTEG in combination with a skin temperature sensor to calculate the core body temperature. The AI algorithm calculates the core body temperature with the highest accuracy in comparison to competing technologies. Due to the heat flux sensor, this technology has a high accuracy even in a not controlled environment (e.g. under the sun, during intense physical activity, and within a large range of ambient temperatures and humidity)

How accurate is the Core Body Temperature reading?

Thermometers should be compared with one of the gold standards. These are artery, rectal, or e-pill measurements. All of the gold standard methods are invasive and thus not easily useable. CORE’s temperature calculation is compared with the e-pill method. The mean absolute deviation is 0.26°C and the 95% confidence interval is 0.67 °C considering every-day life activities. In comparison, a professional tympanic sensor has a confidence interval of 0.5 °C, but only if it is used in a controlled environment while at rest and by a health care professional.

How does CORE compare to other existing thermometers?

How long do the batteries last?

The batteries last for 3-5 days.

Is the product reusable?

The product is fully reusable if used with a chest strap. If CORE is used as a patch, the skin-adhesive tape needs to be renewed after a shower. If the device is changed between persons, it can be cleaned with alcohol.

Which connection methods do you support?

Bluetooth BLE and ANT+ connectivity are supported. CORE is also supporting the Bluetooth thermometer standard. To access data from the CORE from a 3rd party device or app, please contact us.

How many CORE patches can be used simultaneously in one room?

There is no limit on the maximum amount of Bluetooth devices in one place. There is, however, a limit to the number of patches that can be connected to one receiver. This is dependent on your specific use-case. You can contact us for more information.

How can I connect the CORE patch to any other 3rd party visualisation platform (API links?)

Please, contact us for detailed explanations about the process.

Is CORE considered a medical device?

CORE is not a medical device. It is not intended to diagnose, treat, cure, or prevent any disease or health condition. It does not have FDA or CE approval.

CORE should be used by healthy adults in a stable environment and is only meant to inform you about your overall wellbeing. No medical advice can be concluded from the measured temperature data, and it cannot replace the services of health professionals. Deviations from the normal temperature range should be investigated by a health care professional. Never disregard professional medical advice or delay in seeking it because of the temperature measurements by CORE. To read the full disclaimer click here.


Which devices can I connect to CORE?

CORE can connect to Android, iOS, Apple Watch and Garmin ConnectIQ devices.

How can I attach the device to my body?

CORE can be attached to the body with a chest strap, or to the apical chest position with CORE’s skin adhesive tape.

Is the CORE patch waterproof?

Yes, the core has a IP67 rating. IP67 means that the unit can be dropped into a body of water up to a meter deep for half an hour.


What are normal temperature ranges?

It is essential to know that different thermometer methods give different body temperature readings. Generally, a rectal reading is around 0.5 °C higher than an oral reading. And an armpit or forehead scanner is 0.5 °C lower than an oral meeting. Some thermometers take these differences into account and show a temperature with an offset, and some don´t. Therefore it is always important to read the user guide. Our value is the actual (rectal) core temperature. A normal body temperature is between 97°F (36.1°C) to 99°F (37.2°C).

Why do you want to measure your core body temperature continuously?

Your core body temperature is not constant during the day. Tracking your temperature continuously will give you a better insight about your health status. For instance, you can track disease progressions, ovulation, the circadian rhythm, which affects your sleeping patterns, as well as many other use cases.

Can CORE be used as a medical device?

CORE is not FDA nor MedCE approved. So at this point CORE can not be used as a medical device. Please, check our disclaimer for more information. We will inform you if in the future we will launch a new CORE product which will then undergo FDA approval.
