Abstract
An apparatus enhances the sense of touch when placed between the fingertips of the user and the object being touched. The apparatus comprises a liquid lubricant inside a sealed enclosure. The enclosure is formed of a pliable, elastic material having a wall thickness of about 0.005 to 0.020 inches. The liquid lubricant is present in an amount sufficient to fully coat the interior of the enclosure, but which also permits the enclosure to be flattened with at least about 75 percent of the surface area of one side in contact with the other side.
