Overview
Calera® is CORE’s premium core body temperature monitoring solution for research use cases. The innovative sensor technology is built into a compact waterproof device that can be comfortably worn during controlled study settings, sports activities, at work, or all day long. CORE Calera® comes with functionalities and services specifically designed for research purposes, including access to high resolution data and several benefits often appreciated by researchers.

Advantages

• Raw Data Access
  • More data stream; e.g. core temp / skin temp / accelerometer / Heart rate (external device) / Heat flux*
  • Highest resolution: 1 measurement per second
  • For the most precise data during sports activity, pairing with a heart rate monitor is recommended to help convert measured heat flux into core body temperature. During everyday (non-sports) activity, core temperature data is accurate with or without a heart rate monitor.
• Remote Support
  • Assistance in setting up studies
  • Data interpretation support
• Highest Accuracy
  • Each CORE Calera® device undergoes individual calibration for heat flux and skin measurements to ensure optimal accuracy across devices.
• Store Data on Calera
  • Up to 6.5 days of on-device storage
  • No data loss due to poor connection
• Research Tool
  • Control multiple devices simultaneously from PC/MAC
  • Download data in accessible .csv files

*Heat flux is available on agreement.

The Technology
Calera® is a wearable device that enables accurate, non-invasive, and continuous core body temperature monitoring. The technology combines heat-flux and skin temperature sensors with machine learning algorithms trained on over one million data points to calculate core body temperature. Heat‑flux measurement is based on a Seebeck-type sensor that generates a voltage proportional to heat passing through the sensor, enabling robust estimation of thermal energy transfer independent of physical activity and environmental conditions.
