Withings’ new generation consumer wristwatch ScanWatch 2, can now track core body temperature 24/7

greenteg, the Swiss-based innovator in sensing technology, has collaborated with WITHINGS on their new generation hybrid watch ScanWatch 2, which includes an additional health matrix to track body temperature. With the integration of greenteg’s CALERA® technology, this latest hybrid watch offers a revolutionary advancement in how health-conscious individuals monitor their health and well-being.

WITHINGS’ hybrid watches have health as their priority focus. ScanWatch 2 is a wristwatch providing a single-lead medically cleared ECG function with atrial fibrillation detection with the ability to continuously monitor health biomarkers such as body temperature, heart rate variability, respiratory rate, and female menstrual cycles.

The new ScanWatch 2 can be pre-ordered now in various designs through their website www.withings.com and will be launched at the upcoming IFA trade fair held in Berlin from 1 – 5 September 2023.

“We are proud to announce that WITHINGS has integrated our CALERA® technology in their new generation of hybrid watches, ScanWatch 2. CALERA® is a unique sensor technology for core body temperature monitoring, meeting the demands of the growing health-conscious consumer market segment,” said Dr. Lukas Durrer, greenteg’s Co-Founder. “This collaboration embodies our commitment to pushing the boundaries of innovation, ultimately empowering individuals to take charge of their health like never before.”

Why tracking body temperature is important.

CALERA® is a wearable sensor technology for tracking body temperature continuously and non-invasively via a miniaturized heat flux sensor, combined with a powerful algorithm and a patented thermal integration design.

This technology is the culmination of more than a decade of research, conducted in collaboration with leading sports and medical research institutes and partners in Switzerland and the European Union.

By integrating greenteg’s CALERA® core body temperature monitoring sensors in consumer wearables, unprecedented insights into day and night body temperature fluctuations are provided. Additionally, the data allows health-conscious individuals to optimize fitness routines.

The partnership with WITHINGS represents a significant stride towards personalized health management, combining greenteg’s expertise in sensor technology with WITHINGS pioneering in digital health.
