HMIs with Integrated Smart Functions

HMIs are traditionally just a keyboard and as such just a piece of wire with a metal spring to close an electrical contact. Over time such membrane keyboards very quickly evolved to have more functions than just switches. Integrated LEDs and illuminated emblems are state of the art. Integrating displays or microcontrollers is making HMIs smart. In this class we will see the technological possibilities and real-life examples of integrated smart functions in HMI systems. The examples show integrated displays, touch buttons including their electronics and novel printed sensors. Furthermore, the integration of transparent heaters, antennas or shielding will be outlined as this will be the next level of integration to a smart HMI.
