Abstract
Nowadays, information transmission devices, which activate the human tactile sense, are commonly available for Braille generation to support the blind and on the enhancement of the gaming experience with a vibrating gamepad. The generation of real surface structures with a device, a so-called tactile display, has not been solved satisfactorily so far. A new approach is to generate a stress-strain-distribution in the finger similar to that, which occurs while moving a finger over a surface, so that the tactile perception is alike. Vibrations generate the stress-strain-distribution. To realize this in a tactile display, interdisciplinary knowledge is necessary. The actuators of the display have to address the different stimulation processes of the individual mechanoreceptors in the skin. In addition, every person has individual tactile impressions according to the fingers physiology. In order to satisfy this requirements, small, powerful and high dynamic actuators are needed. Furthermore, the current load characteristic of the actuator is always needed for control. In this work, our novel tactile displays to stimulate the mechanoreceptors of the human finger by suitable frequencies and amplitudes are discussed in detail. The self-sensing concept is presented to obtain online the individual actuators displacement and force.
