Abstract
A haptic glove comprises a glove body including a glove digit corresponding to a phalange of a user hand with the glove digit having a bend location that is located along the glove digit. A haptic apparatus is coupled to the glove body at the bend location with the haptic apparatus comprising a plurality of sheets that are flexible and inextensible and a pressure actuator coupled to one or more of the plurality of sheets. The plurality of sheets are stacked and configured to translate relative to each other along the centerline with bending of the glove digit. The pressure actuator is configured to adjust an applied pressure to the plurality of sheets to adjust friction between the sheets. The adjustment of friction is proportional to a bending resistance of the glove digit.
