Abstract
Origami-based contact members, devices and systems used for active mechanical haptics. The origami-based contact member includes a top plate, a bottom plate, and at least one piece of a curved origami-based metamaterial interposed therebetween, with its top end fixed to the top plate and its bottom end fixed to the bottom plate, the top plate is exposed to be contacted by a user's body site. The metamaterial includes a panel having a single curved crease extending in its longitudinal direction, which divides the panel into two facets. The panel is foldable along the single curved crease to form a folding angle between the two facets. The folding angle is adjustable by rotating the bottom plate to achieve a variable stiffness when loaded in a vertical axis between the top and bottom plates, covering positive stiffness to negative stiffness, to be perceived by the user's body site via contact with the top plate.
