CORE Launches Calera®: a Research-Grade Core Body Temperature Sensor Built For the Lab and the Field

CORE, the leader in continuous, non-invasive core body temperature monitoring, today announces the launch of CORE Calera®, a research-focused continuous non-invasive core body temperature sensor designed to meet the rigorous demands of scientific and clinical investigation.

Born out of the labs of ETH Zürich, CORE has deep roots in academic research and thermal physiology. After several years serving elite athletes and performance-driven consumers with CORE 1 and CORE 2, the company is returning to its origins by expanding its platform to support researchers with a purpose-built solution that delivers enhanced accuracy, higher-resolution data, and seamless cloud-based insights.

Built for Research Precision

CORE Calera® is engineered specifically for research applications, offering:

  • Continuous, non-invasive core body temperature monitoring
  • High-resolution data capture at 1 Hz (one data point per second) — compared to 1-minute resolution in CORE 2
  • Individualized calibration protocols to achieve research-grade accuracy
  • Dedicated CORE cloud dashboard for study management, data visualization, and export
  • And more: https://corebodytemp.com/pages/research

Trusted by Leading Institutions

CORE Calera® has already been deployed by world-renowned institutions including:

  • Duke University
  • Hokkaido University
  • Michigan State University
  • National University of Singapore
  • Prince Sultan University
  • University of Cape Town
  • And many more

Researchers are leveraging CORE technology across diverse applications, including sports performance, occupational health and safety, sleep and circadian rhythm research, women’s health and hormonal cycle studies, and other emerging topics. Some of the most recent publications using CORE Calera® include:

  • Four-Week Heat Acclimation Lowers Carbohydrate Oxidation of Trained Runners During Submaximal Exercise in the Heat (2025)
  • Cognitive Performances During Sleep Restrictions in Thermoneutral Indoor Environments (2025)
  • Multi-Wearable Approach for Monitoring Diurnal Light Exposure and Body Rhythms in Nightshift Workers (2025)
  • See a full list of publications here

Bridging Lab and Real-World Environments

Unlike traditional invasive temperature measurement methods, CORE Calera® provides accurate core temperature data without disrupting natural movement or behavior. The wearable sensor design allows for laboratory-level insight in real-world environments—making it uniquely suited for ecological research and longitudinal monitoring.

“CORE was founded in research, and CORE Calera® represents a natural evolution of our mission,” says CORE CCO, Ross McGraw. “We’re proud to equip researchers with a scalable, high-resolution solution that enables deeper insights into human thermophysiology, without compromise.”
