Selective stimulation to skin receptors by suction pressure control

In previous works, we have proposed two methods for whole palm-covering tactile display. One is "suction pressure stimulation" and the other is "multi-primitive tactile stimulation". In those studies, we used two pressure patterns as "primitives" which were considered to be significant patterns to create real tactile sensation. In this paper, we clarify the relationship between the primitives and response of mechanoreceptors using 3D FEM analysis. The results indicate that two primitives activate two superficial mechanoreceptors RA and SA I selectively.
