The requirements of the automotive industry are high for both interiors and exteriors. This was also the case for the attenuator in the new Audi A3, model AU380. It was meant to not just blend into the classy, high quality design of the sedan, but also to function flawlessly. And of course, strict industry specifications had to be met. This required special sensor solutions.
For its capacitive attenuator, automotive supplier Preh sought a sensor manufacturer who met the VW standard and the standards of other premium manufacturers. Both driver and passenger were to be able to easily operate the controller, mechanically and by touch. Another requirement called for allowing a manufacturer complete freedom of design for whatever occurred to them, like backlighting, ambient lighting, and deadfront design, which does not reveal its functions until touched.
The PolyTC® sensor from KURZ subsidiary PolyIC fulfills all wishes. The sensors are laid out on a metal mesh: razor-thin silver conducting paths lie latticed on a transparent PET substrate, and another transparent PET layer seals the layout. The sensor transfer products remain highly flexible. They are manufactured in the roll-to-roll process in a single work step. Even high print runs come out quickly and reliably. And electrical connection parts can be produced right alongside. Mechanical weak points, which have a negative effect on the service life of the end product - in this case the attenuators - are omitted. Another plus is that the Indium-Tin-Oxide (ITO) normally applied is replaced by the silver microstructure. Customers benefit from higher performing products, as well as from more cost-efficient, economical and sustainable processes than conventional solutions.
