At this time vision is no longer sufficient, as the mechanical properties of the object cannot be determined by vision alone. Such interactions are now understood to be important for human tool use and judging the texture of an object. Tactile sensors are generally modeled after the biological sense of cutaneous touch which is capable of detecting stimuli resulting from mechanical stimulation, temperature, and pain (although pain sensing is not common in artificial tactile sensors). Generally, the dielectric constant value of the liquid being measured is required, to enable calibration of the sensor at its ‘full’ level. The stimulus-to-response pathways seen in electronic touch sensor operation mimics the human body process that involves our skin, signal transmission via the nervous system, and brain. As the touch sensor will be used in an industrial application, it will need to be robust and protected from environmental damage. The model shows a superior accuracy compared to other sensors and methods. Which type of sensor is a tactile sensor. The principle of induction position sensing is a 3 step process. They are used in robot grippers as well as flat tactile arrays.
