gSKIN® Heat Flux Sensor
gSKIN Positioning Sensor

Fast and precise thermal measurements

The gSKIN® Heat Flux Sensor helps increase energy efficiency, improve material quality, or add decisive functionalities to your product. Heat flux sensing helps you better understand the thermal characteristics of your materials and processes.  The gSKIN® Heat Flux Sensor is applied in thermal measurement and control systems where precision and speed are of high importance.

Advantages of the gSKIN® Heat Flux Sensor:
  • Fast Response Time
  • Minimal Invasiveness
  • Easy to use
  • Customizable design
  • Robustness
  • High Sensitivity



Like the human skin, the gSKIN® Heat Flux Sensor is able to measure three different types of heat transfers, namely conduction, convection, and radiation.

Integrate the ability of the gSKIN® sensor to measure heat flux through materials to quantify the heat output of chemical reactions or to measure energy efficiency in buildings.

Use the gSKIN® sensor to measure heat fluxes through liquids and gases for non-invasive flow measurement or fluid detection.

The ability to measure heat fluxes through electromagnetic waves makes the gSKIN® the ideal tool for solar radiation, infra-red and laser power sensing.

The gSKIN® Heat Flux Sensor generates an output voltage which is proportional to the local heat flux. In order to calculate the heat flux, the output voltage must be divided by the sensor sensitivity.

greenTEG won the Product Award 2013 of the Swiss Excellence Foundation for its heat flux and radiation sensor technology.
