Tactile Sensors for Quantitatively Evaluating Tactile Properties of Fabrics



Tactile properties of object surfaces that we feel through touching them are very difficult to describe in quantitative/objective measures. Even today, evaluation of such properties depends on either of expert skills or expensive precise measurement devices. Making such evaluation process simpler and more reliable will contribute the reduction of production costs and the sustainment of production qualities.

In this research, we are developing tactile inspection systems for inspection processes in the industry, especially of fabrics. Our main interest is to realize compact, low-cost, easy-to-use devices that can be used in hand-held or finger-mounted manners.
