Get quality core body temperature data with CALERA® Research
Replace traditional and subjective monitoring tools with accurate core body temperature data collected remotely, non-invasively, continuously, and conveniently from the participants' home.
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.
Making Data Collection Easy for Everyone

Stanford University’s Sleep Study Awarded in First Call for Proposals
In May 2024, greenteg concluded its first call for sleep research proposals. Researchers from Stanford University—Professor Jamie Zeitzer, Lara Weed, and Dr. Renske Lok (left to right on photo)—have been selected for their study.
Their research will focus on the interaction between sleep, central and peripheral oscillators, and menstrual phase, aiming to understand its collective impact on overall health and well-being. Core body temperature changes will serve as a key metric in their research.
