摘要: This Letter presents a capacitive-based sensor system for fingertip contact applications. It is capable of simultaneously measuring normal (pressure) and tangential (shear) stresses at the interface between external objects. could be potentially exploitable applications in fields upper limb prosthetics, robotics, hand rehabilitation so on. The was calibrated its performance tested using test machine. To do so, specific protocols reproducing typical stress profiles interactions were designed. Results show system's capability to measure applied pressure stresses, respectively, with high linearity measured stresses. Subsequently, as case study, 'press-drag-lift' based conducted by finger healthy subject. provide an initial evaluation real-life study results indicate that both shear indeed simultaneously, which aligns well designed protocols. potential corresponding future works are also discussed.
