Abstract

A haptic system includes a structure having a conductive layer and a reactive layer. The conductive layer is coupled to a power source and the reactive layer is coupled to a switch having a first state and a second state. The power source enables the conductive layer to generate a charge. The first state of the switch operates the reactive layer to block the establishment of a tissue-stimulating electric field. The second state of the switch operates the reactive layer to enable the establishment of a tissue-stimulating electric field to generate a touchless haptic effect.
