Haptic Steering Wheel

The concept is based on the idea of using the steering wheel as an input & output device. Different zones with integrated piezoelectric actuators let you perform swipe, tap and press commands or deliver haptic input confirmation and alert signals.

Piezoelectric actuators

Piezoelectric materials are touch sensitive but can also vibrate. Therefore, this one material can be used both ways for receiving and for sending signals. Researchers from CEA – Liten and Arkema developed this material further to improve its sensitivity and vibrating performance.

These actuators were screen printed on a stretchable TPE foil so that they can be applied onto the double-curved surfaces of the steering wheel rims.

Tactile zoning of surfaces

To make it easier for the user to sense where the active and vibrating areas are located, we experimented with embossing different textures into the steering wheel leather skin. Furthermore, we explored if different textures deliver a distinguishable sensation in the palm of your hand.
