In manufacturing quality-check processes, there are numerous situations where skilled workers are often called upon to evaluate surface roughness with their sense of touch. However, this method is non-quantitative and is dependent on the skill and experience of the workers. Therefore, the development of a measurement device that can acquire quantitative surface profile data more easily than existing equipment is required. In this study, we developed a prototype portable, manually operated, tactile sensor system that utilized two cantilever-structured thin-plate tactile sensors operating in tandem. The tactile sensors consisted of piezoelectric polymer film (PVDF) that served as strain detectors. Since it is necessary to measure the amount of tactile sensor movement in order to evaluate surface roughness, this system calculates time delays between the two sensor signal outputs, thereby allowing sensor head movement amounts to be determined during measurement operations.
