Product overviewCalera® 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® provides functionalities and services specifically designed for research purposes, including access to high-resolution data and benefits often appreciated by researchers.
Advantages- Raw Data Access: More data streams (e.g. core temp, skin temp, accelerometer, optional heat flux, heart rate from external device). Highest resolution at 1 measurement per second. For highest precision during sports activity, pairing with a heart rate monitor is recommended; during everyday activity core temperature data is accurate both with and without a heart rate monitor.
- Remote Support: Support for study setup and data interpretation (service offering).
- Highest Accuracy: Each device undergoes individual calibration for heat flux and skin measurements to ensure optimal accuracy across devices.
- On-device Storage: Up to 6.5 days of storage time; no data loss due to temporary connection issues.
- Research Tool: Control multiple devices simultaneously from PC/Mac and manage download of data in easily accessible .csv files.
What the technology measuresCalera® uses a combination of heat-flux and skin temperature sensors plus machine learning algorithms trained on large datasets to calculate non-invasive, continuous core body temperature. Heat-flux measurement is available under agreement and is a key differentiator for accurate thermal energy transfer estimation.
