Abstract
A woven strap that may be comfortably worn on the wrist to drain or wick static electrical charges from the wearer. Conductive fibers on the inside surface of the strap contact the skin and conduct electrical charges to a grounding cord attached to the strap. Face yarns exposed on the outer surface may be woven to form designs. The woven fabric material of the strap is attached to a clasp allowing the strap to be adjustable in size. Because of the woven nature of the fabric material and the adjustable clasp, the strap is more comfortable than other conductive elastic wrist straps. The woven fabric material is particularly advantageous because it stretches easily, it is inexpensive, and it does not roll over onto itself as it is being drawn over the hand.
