CORE | Thermal Sensor Technical Specifications
This short note presents the base technology with the thermal sensor technical specifications and features that can be found at the bottom of CALERAresearch for Research applications and CALERA® Development kit for OEM integration.
About CORE features
CORE is the first non-invasive wearable that allows for continuous core body temperature measurements under real-life conditions with great accuracy
Our patented novel sensor allows to accurately monitor core body temperature just through skin contact.
Artificial Intelligence Algorithm
CORE uses a machine learning based algorithm to calculate and analyze core body temperature in real-time.
Comfortable and lightweight
The device is easily mounted on a chest strap or attached with a medical grade patch. It is water-resistant and can be sanitized using alcohol.
Connect with your device(s)
CORE connects wirelessly with Garmin, iOS and Android smartwatches and smartphones.
Long battery life allows monitoring core body temperature for longer periods (over 6 days) without interruption.
Multiple patches can be operated with the same smartphone. The BLE standard temperature profile allows to stream the data on any BLE compatible device.
