The sensors of the ADAS system, such as cameras, radar and lidar, must be able to work accurately in all weather conditions. Especially when driving at extremely low temperatures, the sensor must be quickly de-iced and ensure that the sensor does not freeze. According to foreign media reports, in order to solve this problem, Schreiner ProTech in Munich, Germany has developed a thin film heater based on printed electronics.
The functional film is light, flat and flexible, so it requires less space and can be installed close to the sensor or directly on the sensor, which is very suitable for this specific type of application. The flexibility of the membrane and the flexible design of the conductive tracks allow the membrane heater to be customized according to shape and size, and to adapt to the geometry and curvature of the assembly. Thanks to advanced die cutting, laser and printing technology, complex contours with tight tolerances can be achieved. The surface of the printed heating structure is flat to avoid exposure of conductive traces after installation. The heating solution also has a self-adhesive version, reducing installation requirements.
In this scheme, individual heating performance can be adjusted according to parameters such as temperature, voltage, surface heating performance and uniformity. This flexible solution can meet various environmental conditions and customer needs. The thin-film heater can be installed near the sensor, so it can be quickly heated to ensure the reliable performance of the sensor. In addition, the product can also be integrated into the customer's existing process through adhesive bonding, insert molding and clamping.
