摘要： A device includes a substrate and a set of force sensors supported by the substrate. Each force sensor includes a pillar extending outward from the substrate, each pillar comprising a stack of semiconductor layers, the stack of semiconductor layers being configured to emit light upon biasing of the stack of semiconductor layers, and post disposed along only a portion of a perimeter of the pillar such that, taken together, the pillar and the post have an asymmetrical cross-sectional shape. Each pillar has a cross-section elongated along an axis. An orientation of the axis, and a peripheral position of the portion of the perimeter at which the post is disposed, differ across the set of force sensors such that a variation in light emitted by the stack of semiconductor layers of one or more of the force sensors is indicative of a direction of a shear force applied to the set of force sensors.
