Fischer Automotive and TactoTek have prepared a technology demonstrator for electronic functions and manufacturability of smart surfaces.

“How parts integrate within future vehicle interiors as well as the individual functions and design elements must be considered together. Moreover, user interfaces must deliver intuitive operation, and increasingly use patterns are driven by consumer electronics,” said Johannes Konrad, Head of the Management Board from Fischer Automotive.

The demonstrator features sensor surfaces for operating command input that are illuminated with LEDs moulded directly into the plastic that forms the engineered structure of the part. In addition to individual sensors, a raised round knob is used for multi-touch rotary inputs. The knob is enhanced with tactile features to guide users. Illumination is used for styling, guiding interactions and communicating vehicle status information to the driver.

In the design, the human-machine interface sensors, circuitry and lighting are integrated within a seamless single piece injection molded part that also provides the mechanical structure and is only 3mm thick. The part is designed and manufactured using TactoTek IMSE technology, which combines printed electronics and electronic components within single, seamless 3D injection moulded structures.
