This paper discusses the design of microstructure on a handle or handrail of welfare equipments to prevent slip accidents. Friction between a rubber block and a rigid body were measured on a original set-up. The rubber and the rigid body simulate human finger and handel respectively, and deterministic microstructures were fabricated on both surfaces using photolithography process. The effect of typical parameters were made clear including the effect of environments, dry or water between the surfaces. It was found that proper microstructure keeps the factional foce almost constant independent of conditions. It was also found, based on sensory tests, that structural pitch 300mm can minimize the pains while keeping frictional force properly.
