Introduction

gSKIN® Heat Flux Sensors can be applied in various scientific research areas. Their aim is to improve thermal processes, enhance characterization of certain materials or improve existing/new models of material properties. In this section you will find peer-reviewed academic publications with use of our sensors.

We are proud to state that various renowned academic institutes, including ETH, HKUST, SUNY, all of which have used our heat flux sensor and achieved incredible results.

Three of the most striking advantages of gSKIN® Heat Flux Sensors are:
