Active haptic feedback makes user interfaces and operating elements safer, more intuitive, more comfortable and of a higher quality. Gruner has in-depth expertise in the field of tactile feedback technology and offers customer-specific solutions and standard actuators for all types of operating systems. Whether for displays, touchpads, light strips, steering wheel switches, gear selector switches, overhead consoles, or smart surfaces. 

Product highlight are Gruner's new HSA actuators, which will be integrated into the demonstrators. HSA (Haptic Sense Audio) actuators are three-in-one actuators, combining haptic feedback, force sensing, and audio output.  

Advantages: 

·        Maximum flexibility of the haptic signal:  The direct drive concept enables a wide variety of signal shapes over a broad frequency range. 

·       Extremely precise feedback: There is no latency and very short event times can be achieved (<9- 15ms). 

·       Variable application: The actuators are available in different sizes, for single buttons to large displays.
