Core body temperature for OEM integration and B2B / White Labeling
The combination of Recon Health’s novel Health System-on-a-Chip technology and greenTEG’s industry-leading core body temperature solution will allow to better monitor patients at home and to address more health conditions as compared to products on the market today.
Scott McMillan
CEO, Recon Health
Our deep and friendly collaboration realized Cardiowatch 287, a validated medical grade, multi-sensor, convenient bracelet for continuous monitoring of cardio-respiratory function, an important and revolutionary solution that will help save lives!
Peter Stras
CEO, Corsano HealthIt is amazing on how many levels greenTEG and Leitwert complement each other. From early prototyping to medical use-cases, a truly great partnership with many chapters still to be written.
Lukas Gasser
co-founder, LeitwertgreenTEG is the leader in core body temperature monitoring, having developed the world’s first core body temperature sensor for continuous and non-invasive measurements. With the COVID-19 pandemic, health has become an even more critical issue along with individuals and organizations. We partnered with greenTEG to provide an easy-to-use solution using the high accuracy CORE sensors to help maintain people safe.
Nuno Gonçalves
CEO, EmituCore body temperature for Sport Performance Evaluation

The reason why we’re measuring the core temperature all the time is to get a better understanding of the intensity versus the output. We’ve measured the power on the bike and then see how it compares to my heart rate. And now we can even do it with the core temperature to see how much the core is increasing at a high intensity in the same way we can see how the heart rate is ramping up and up and up and maybe even getting to a plateau
Kristian Blummenfelt
Olympic Gold medallist and Ironman World Champion
The really true value of it, compared to, for example a pill, is that we can collect data continuously over time, every training session, because it just sits on the heart rate monitor belt. So, when you bring on your heart rate monitor belt it’s there, and we get the data along with power, heart rate, core temperature and other metrics too. And for those big trends there’s nothing that beats it.

R&D Sensing

At our Battery Calorimetry Lab the gSKIN® Heat Flux Sensor facilitates the determination of the heat transfer coefficient for Lithium-ion batteries that is necessary to transfer the measured temperature data into heat data. These data help to improve the thermal management system for the batteries, making them much safer.
