We have developed a tactile sensor for tactile tele-presentation systems by focusing on four features of the human finger considered to play an important role in texture perception; the existence of nails and bone, the multilayer structure of soft tissue, the distribution of mechanoreceptors, and the deployment of epidermal ridges. As a result, the developed sensor could detect roughness, softness...
Under DC voltage stress, a negative hetero-charge is generated near the positive electrode in cables insulated with cross-linked polyethylene (XLPE). The generation of negative hetero-charges in XLPE-insulated cable results from cross-linking byproducts, antioxidants, and moisture. Among these inclusions, moisture is known to originate from dehydration of a-methyl styrene, which is a byproduct produced...
This paper presents a hybrid tactile displaying method of realistic texture using ultrasonic vibrator and force display. The aim of this study is to display various realistic tactile senses by controlling multiple factors including roughness, softness and friction sense. First, a tactile displaying system was configured for displaying roughness, softness and friction sense simultaneously by compensating...
