Abstract
Sensor system for haptic display is important to achieve the feedback of the sense of force in the actuator control. We have proposed a haptic sensor system composed by thin and flexible sensor unit to measure contact pressure and shear stress.
In this study, a sensor system of both the contact pressure and the bi-axial shear stress, which can measure the three dimensional vector information, was developed by improving our previously-developed sensor unit. The wearable sensor system applied to human body and investigates the stress value in several cases of motions. The effectiveness of the sensor system was discussed through those actual measurements.
