Tactile sensors are commonly used in industrial, medical or virtual-reality applications, but the majority of commercial tactile systems are capable to detect pressure maps only. In this article we present a novel tactile sensing array that processes all three components (normal and shear) of the tactile information at every sensory element (taxel, tactile pixel). We describe the processing technology of the integrated micro-sensors, write about the information coding behaviour of its elastic cover and, finally, we show a robotic application example, where the three-component force measurements play a fundamental role.
