Who is greenTEG?

greenTEG’s team develops, manufactures, and markets thermal sensors for heat flux and laser power/position measurements and provides consulting on the thermal integration of its products. Today, greenTEG supplies OEMs as well as scientists in corporate and university labs around the world with its unique products.  All sensors are fully developed and manufactured in Zurich, Switzerland.


greenTEG’s board of directors is presided by Gianni Operto and consists of investors and independent members. The board brings in comprehensive experience and network in entrepreneurship, finance and the energy business.

Our Vision

We believe that IoT (Internet of Things) solutions will be essential in the future to improve the daily life by facilitating processes and workflow and optimizing time and energy consumption. With its unique technology – CORE body temperature monitor, greenTEG created the first non-invasive wearable that allows for continuous core body temperature under real-life conditions with great accuracy. This IoT-based technology offers a great support for the development of future technologies for remote patient monitoring, workplace Health and Safety, Sleep and Fertility tracking.  

 

Our Mission

“Developing cutting-edge sensor technologies to support innovation for various industries, while building an exceptional workplace and company which serves employees and customers based upon our sustainability linked values.”
