Estimating the term…
Tactile sensing using both coarse and fine tactile sensors. A coarse tactile sensor having a first sensitive area at least partially encompasses or overlies a plurality of fine tactile sensors, each having a respective sensitive area smaller than the first sensitive area. The coarse tactile sensor(s) and fine tactile sensors may be carried on a same circuit board or separate circuit boards. Processor(s) circuits are communicatively coupled to the coarse and/or fine tactile sensors. Information indicative of at least a presence or absence of force or pressure at a given location monitored by the respective tactile sensor, and/or a measure of the force or pressure or strain is collected. Such may be mounted to a backing, and optionally covered or encased in an artificial skin. Collecting sensor readings employs both coarse and fine tactile sensors, sampling corresponding fine tactile sensors in response to detection by a coarse tactile sensor.
An apparatus to provide tactile sensing, comprising:
A method to provide tactile sensing using a first coarse tactile sensor and a first set of fine tactile sensors, the first coarse tactile sensor having a respective sensor surface area over which the first coarse tactile sensor is responsive to at least one of force or pressure, the respective surface area of the first coarse tactile sensor having an area greater than a first value, and the first set of fine tactile sensors comprising a plurality of fine tactile sensors, each of the fine tactile sensors of the first set of fine tactile sensors having a respective sensor surface area over which the fine tactile sensor is responsive to at least one of force or pressure, the respective surface area of each of the fine tactile sensors of the first set of sensors having a respective area less than or equal to the first value, the plurality of fine tactile sensors of the first set of fine tactile sensors arrayed with respect to one another, the arrayed fine tactile sensors of the first set of fine tactile sensors delineating a first arrayed footprint of the first set of fine tactile sensors, wherein the first coarse tactile sensor overlaps at least a portion of each of the fine tactile sensors of first set of fine tactile sensors, the method comprising:
