Printed surface heating

Hybride Textilen

"Either drive, heat or shine - this is the principle of e-mobility," explains Michael Steidle, Managing Director of Heinrich Mayer GmbH, Meßstetten. The company has an alternative: a textile carrier material reminiscent of a diving suit is printed with a 3D heating paste made of carbon nanotubes. Light, flexible, formable and energy-efficient, this composite material can be used as a heating door trim in an electric vehicle. Because the heating paste is applied to the back of the textile, the front is open to customer requirements - or for further functionalities. Steidel: "We have the option of printing the front with a conductive carbon paste and thus operating the window regulators, for example".

The Mayer textile printing company estimates the heating output of this intelligent textile at around 10 watts, and the application rate is 12 volts. Radiated from the surface of the driver and passenger doors, this is sufficient to heat the interior of the vehicle, according to the developers.
