Winner of the category “Public Choice Award”: 3D Formed Touch Sensor

HDM Hochschule der Medien, Germany

It is a human-machine interface by Hochschule der Medien which can be used in automotive applications or other control functions based on printed touch sensors formed in 3D. In the diamond-shaped part of the demonstrator, three touch buttons are implemented that work with printed piezo effect technology. The force required prevents unintentional actuation and has improved performance when wearing gloves. The slider with six positions consists of capacitive touch sensors. The technical user interface is integrated in a visually and haptically appealing shaped surface.
