Get quality data for your research with CALERA®

Replace traditional and subjective monitoring tools with objective core body temperature data collected remotely, non-invasively and conveniently from the participants' home.


CALERA® Research for Core Body Temperature Monitoring

CALERA® Research is a Swiss patented heat-flux sensor and research device that eliminates outside environmental influences when monitoring core body temperature, and therefore delivers accurate results independent of the user’s physical activity level or external conditions.

The device provides access to high-resolution (1Hz) raw data including Core Temperature, Skin Temperature, Accelerometer, and Heat-Flux. Data is easily collected remotely, continuously, and non-invasively simply on skin-contact, thereby increasing participant efficacy.

What data can I obtain from the device?

The device provides access to high-resolution (1Hz) raw data including Core Temperature, Skin Temperature, Accelerometer, and Heat-Flux.

How far does Bluetooth reach?

Bluetooth's limited range matters only during initial device connection. Once in logging mode, distance isn't a concern. CALERA® Research device can track core body temperature of users wherever they may be—whether at home, at work, or even in another country.

Data is stored and later downloaded from the research tool. 

How many CALERA® Research devices can be connected to the software?

There is no upper limit, with some researchers successfully using over 100 devices.

For which research purposes is the device suitable?

Our device can be implemented in various research scenarios where monitoring core body temperature is relevant.

We are collaborating with research partners working in fields that include but are not limited to sports performance, circadian rhythm studies, occupational health, women's health, neurological diseases as well as other chronic ailments.
