A hand-held friction meter

Abstract

A portable hand‐held friction meter has been devised which will measure the coefficient of friction between a reference material and skin at any body site regardless of position. The reference surface can be made of any of a number of materials, such as steel, nylon, PTFE, leather or even fabrics. The effects of disease and topically applied medicaments on the skin are being studied quantitatively with this machine, which may also have industrial applications.
