Heating Foils

Specially developed for use in modern driver assistance systems: innovative heating foils based on printed electronics.

The road to autonomous driving goes via driver assistance systems. Since 2022, many systems are mandatory to increase road safety. To achieve this, the camera, radar and LiDAR (Light Detection and Ranging) systems used in cars and trucks must function perfectly in all weather conditions. Especially in sub-zero temperatures, it is essential that the sensors quickly become ice-free and remain so for the duration of the journey.

Heating films from Schreiner ProTech based on Printed Electronics and can be mounted in the enclosure of camera, radar or LiDAR systems. They ensure reliable and permanent de-icing of the sensors. The functional films are flat and flexible, making them an ideal solution for heating elements. Thanks to state-of-the-art die-cutting and printing technology, even complex contours with tight tolerances can be realized.

 

Heating foils are very light and can therefore be integrated into the sensor in an extremely space-saving manner.

Your Advantages at a Glance

  • Flat and flexible film structure (approx. 50–300μ) with low weight
  • Flexible material selection according to individual customer requirements and adapted to the respective application: Conductive paste printing, stampings from conductive films, for example copper or aluminum based
  • Transparent film carriers
  • Easy integration into the customer's product due to self-adhesive film equipment
  • Easy contacting with the customer's electronics by plug-in connections, crimping or conductive bonding
