Why monitor core body temperature?

Core body temperature is a vital sign that indicates the internal condition of the body’s organs. It fluctuates with physical activity, sleep and circadian rhythms, ovulation, and various health conditions. Tracking this data helps users optimize performance, detect early signs of illness, and improve recovery and health management.

Non-invasive Medical grade accuracy (1)

Our Advantage

Traditionally, core body temperature has been estimated using skin temperature, which is easily affected by environmental changes. While medical alternatives exist, they are often invasive or non-continuous.

 

The CALERA® solution uses heat flux technology for continuous, non-invasive core temperature tracking, delivering reliable data unaffected by external conditions, such as weather or clothing, empowering users to make accurate health decisions anywhere.

Frequently Asked Questions

What is the accuracy and resolution of the CALERA® solution?

The CALERA® measures core body temperature with a resolution of 0.1°C. With a bias below 0.1°C and a limit of agreement below 0.7°C (at the chest), CALERA® has a better clinical accuracy than most of the common medically certified ear thermometers and it is also better than any skin temperature-based, continuous medical thermometers.

Does the sensor need to be in contact with the skin?

No, our sensor can be mounted inside the housing on a printed circuit board close to the skin facing the housing. Often the sensor is integrated on the same board as a PPG sensor. The housing material can be plastic or glass.

Are there any clinical studies of the CALERA®?

Yes, there are independent studies on the accuracy of our solution for the wrist and chest. Furthermore, we have performed many internal studies showing the accuracy in different use cases.
