Abstract: A dry adhesive structure and a method for manufacturing thereof is disclosed. In an embodiment, the dry adhesive structure comprises a base structure and a plurality of fiber structures is disclosed, wherein each of the plurality of fiber structures comprises a cap structure that substantially overhangs its corresponding fiber structure on at least one side. The method for manufacturing the dry adhesive structure comprises applying a photosensitive material to substrate comprising polymethyl acrylate, patterning and developing the photoresistive material to form a mask comprising the overhanging cap structure, exposing the mask to UV light, developing the substrate to form undercut fiber structures, molding an elastomer rubber materials to form an elastomer rubber negative mold, and molding a flexible polymer material in the elastomer rubber negative mold to form the dry adhesive structure.

Abstract: A fibre-based sensor for yarn senses strain or pressure and includes: (a) a fibre extending along a centerline with a first longitudinal portion thereof forming a first fibre member that is elastic and has a first stiffness, first hysteresis, and first electrical conductivity; and (b) a second fibre member selected as a second fibre or a second longitudinal portion of the fibre, the second fibre member being elastic, having a second stiffness, second hysteresis, and second conductivity, wherein the first and second fibre members are non-slidable relative to each other along the centerline, the first stiffness being greater than the second stiffness so sensor stiffness is dominated by the first stiffness, the first hysteresis being less than the second hysteresis so sensor hysteresis is dominated by the first hysteresis, the first conductivity being less than the second conductivity so sensor conductivity is dominated by the second electrical conductivity.

Abstract: An apparatus for sensing an angular rate of rotation in the presence of linear movement includes: (a) an enclosure for containing a fluid; (b) a heater disposed within the enclosure in fluid communication with the fluid; and (c) a plurality of temperature detectors disposed within the enclosure in fluid communication with the heater and the fluid, the plurality of temperature detectors being arranged symmetrically about the heater such that a superposition of a plurality of differential-temperature indications produced by the plurality of temperature detectors is maximally sensitive to the rotation while being minimally sensitive to the linear movement.In some embodiments, the heater and the plurality of temperature detectors form a gyroscopic unit, and the apparatus includes a plurality of the gyroscopic units having an angular relationship. The angular relationship may have an angular-relationship value defined by a full-circle angle divided by a number of the gyroscopic units.
