    • A microstructure made of flexible material includes a plurality of projections extending from a common substrate. A distal end of each projection includes a resilient flap. All lateral dimensions of each of the projections increase monotonically with increased distance from a surface defined by distal ends of the flaps when the flaps are unbent. Each of the projections extends from the common substrate in a general direction that is locally substantially perpendicular to the surface defined by the ends of the flaps. When a shear force is applied to each of the flaps by relative motion between the flap and a cooperating surface in contact with the flap, the flap bends so as to increase the area of contact of that flap with the cooperating surface, affecting adhesion between the microstructure and the cooperating surface.
    • 由柔性材料制成的微结构包括从共同的衬底延伸的多个突起。 每个突起的远端包括弹性翼片。 每个突起的所有横向尺寸随着襟翼不弯曲时从与翼片的远端限定的表面的距离增加而单调增加。 每个突起从共同的基板延伸,其大致方向基本上垂直于由翼片的端部限定的表面。 当通过翼片与与翼片接触的协作表面之间的相对运动将剪切力施加到每个翼片时,翼片弯曲以增加该翼片与协作表面的接触面积,从而影响 微结构和配合表面。
