“With the support of greenTEG`s U-value KIT we could publish our Thermodynamic measurement results made for our porous, water-resistant multifilament yarn spun from gelatin – this was indeed a great and easy to use measurement device with which we quickly could work on our tasks!”

–  Philipp Stössel, ETH Zürich, Institut für Chemie und Biologie

“Accurate measurement of the absorbed heat flux is fundamental to estimate the efficiency of conversion of thermoelectric modules. When installed in dedicated under-vacuum module-holders, greenTEG’s heat flux meters provide an excellent and easy way to quantify the incoming heat fluxes with negligible lateral thermal losses. At our IIT lab in Milan, greenTEG’s heat flux meters were implemented in a custom system for the thermoelectric characterization of thermoelectric generators, satisfactorily allowing us for accurate and precise estimation of the efficiency of conversion.”

– Davide Beretta, Instituto Italiano di Tecnologia

“Our group at AIT works on the thermal design and the electro-thermal simulation of battery modules and systems. gSKIN® Heat Flux Sensors help us to determine parameters and to evaluate both the models and the design without requiring a large calorimeter.  The voltage response of the sensors is in the range of those of thermocouples, therefore allowing for an easy integration in our test benches.”

– Hartmut Popp, AIT Austrian Institute of Technology, Mobility Department

With Heat Flux Sensors from greenTEG, we are able to measure the thermal behavior of Li-ion batteries under load. The data acquired from the heat flux sensors during thermal characterization tests helps us to parametrize and validate thermal battery models, which are used for the design of battery modules and their cooling systems.”
