Until now, wood in vehicle interiors has primarily symbolized quality and comfort. Hof University is now investigating how real wood surfaces could also be used as smart control surfaces in vehicles in the future.

Wood-effect trim in cars becomes a control surface
In the WoodTouch research and development project, researchers are working to combine sustainable materials with modern electronics. The aim is to create interior modules made of real wood with integrated sensors, which could, for example, replace or supplement control elements in the vehicle. The surface remains visually unchanged: only when a function is required do the corresponding symbols become visible through backlighting.

The basis is a capacitive control panel that recognises touch in a similar way to a smartphone. The sensors are concealed beneath the layer of wood and are implemented using printed conductive inks. The concept also includes translucent veneers through which light can shine from the rear through the wooden surface.

Existing MID (Moulded Interconnected Devices) technology is to be further developed for use in vehicles. Instead of conventional plastic components, the system will utilise, amongst other things, real wood, biopolymers made from renewable raw materials and resource-efficient conductive pastes. The first demonstration component planned is an interior door panel that combines backlit touch functions with other interior elements.
