The system consists of a very thin pad (1.25 mm thick) made of a semiconducting, modulating and self-regulating technopolymer that heats up when electric current passes through it.

The INVISIBLE PAD is powered by low-voltage electricity (230V AC) and is encased in a dielectric protection consisting of a silicone outer cover. The reaction triggered is a molecular vibration of the nanoparticles that generates the progressive heating of the semiconductor polymer.

As the temperature of the mat increases, the nanoparticles contained in the polymer compound move away from each other with a consequent progressive decrease in electrical continuity; the closer the temperature is to the maximum threshold attainable by the polymer, the lower the electrical absorption through the mat will be.

This characteristic, called PTC (positive temperature coefficient), utilises the heating of the material to limit the current in transit (and therefore the electrical absorption) due to the progressive increase in resistance of the semiconductor with increasing temperature.

Therefore, with the same end effect (temperature of the heating element), this semiconductor technology allows a significant reduction in the overall electrical absorption compared to a similar heater with electrical conductors operating on the principle of electrical resistance, thanks to the natural and automatic modulation and self-regulation of the end temperature without any thermostatic control and limiting element.
