ABSTRACT:
A sensory transmitting membrane device having a flexible base material including a plurality of solid or hollow projections integrally connected thereto and extending from opposite sides of the membrane. The projections on one side of the membrane are offset from the projections on the opposite side of the membrane and are positioned so that an edge of the base of a projection on one side of the membrane is in proximity to the opposite edge of the base of a projection on the other side of the membrane, whereby a linear motion of one projection in a direction parallel to the membrane results in a similar motion by any cooperating projections, to thereby enhance the transmission of tactile sensations from one side of the membrane material to the other side. The sensory transmitting device is particularly useful in latex or rubber surgical gloves, finger cots or condoms.
