The Thin Film Module has been created to analyze samples of single layer thin films (from 10 to 2000 µm) like polymer films, paper, aluminium deposit, thermal insulating layers or tissue.

The sensor is placed between two pieces of the thin film. This set-up is backed up with a very conducting material (stainless steel or soapstone for instance). A continuous electric power is sent in the double spiral.

For the Thin Film Module, the sent power is between 0.5 and 2 W. The manipulation time is between 10 and 40 s, and the sensor diameter is between 20 and 60 millimeters.
Of course, these parameters depend on layer and nature of material to characterize. While measurement, pressure evolution inside the spiral is recorded. This pressure is proportional at the temperature evolution on the sensor surface.

During experimentation, from temperature data, thermal conductivity of the thin film,  thermal conductivity, thermal diffusivity and specific heat capacity of the conducting material are calculated.
