Data glove
First Claim
1. A data glove for use with a user'"'"'s hand, comprising:
- a glove portion fittable on the user'"'"'s hand, the glove portion having an inner layer portion;
a sensor layer integrally attached to an outer surface of the inner layer portion for movement therewith, the sensor layer including a strain sensor embedded within a conductive rubber matrix and including a metal foil having a first gap therein, the first gap filled with an insulating material, a first electrically insulating material contacting a first surface of the metal foil, a second electrically insulating material contacting a second surface of the metal foil, and the conductive rubber matrix contacting the second electrically insulating material, wherein the second electrically insulating material is formed with at least a second gap to expose portions of the second surface of the metal foil to the conductive rubber matrix to conduct an electrical current between the exposed portions of the metal foil through the conductive rubber matrix; and
an information port connected to the strain sensor, the information port being connectable to an external circuit.

Abstract
A sensor material for fabricating instrumented clothing includes conductive rubber layer. Two electrodes are disposed within the rubber layer, are connectable to an external circuit and are separated by a separation distance to form an electrical path from one electrode to the other through an intermediate portion of the conducting rubber layer. The electrical resistance measured between the electrodes is indicative of strain in the intermediate portion of the conducting rubber layer, thus permitting measurements of movement of the fabric to be made. The fabric may be used to form articles that a user can wear, including a data glove, so that movements of the user may be detected and measured.
