Abstract: At least some embodiments of the present disclosure direct to an electrostatic sheet jamming device formed by a sheet having a conductive layer and a dielectric layer. The jamming device includes a first section of the sheet, the first section being separated from the sheet, and a second section of the sheet, the second section being separated from the sheet. The sheet is non-extensible and flexible. The first section and the second section are slidable relative to each other in a first state. The first section and the second section are jammed with each other in a second state when a voltage is applied between a conductive layer of the first section and a conductive layer of the second section.

Abstract: The disclosed technology relates to lubricants for driveline and industrial gears containing a combination of viscosity modifiers along with optional esters, as well as a method of lubricating driveline and industrial gears with such a lubricant.

Abstract: At least some embodiments of the present disclosure direct to an electrostatic sheet jamming apparatus comprising a first sheet comprising a first conductive layer, the first sheet comprising a set of first features, a first dielectric layer, and a second sheet comprising a second conductive layer and disposed proximate to the first dielectric layer, the second sheet comprising a set of second features. The first dielectric layer is disposed between the first conductive layer and the second conductive layer. The first sheet and the second sheet are non-extensible and flexible. The first sheet and the second sheet are movable relative to each other in a first state. The first sheet and the second sheet are jammed with each other in a second state when a voltage is applied between the first conductive layer and the second conductive layer.

Abstract: At least some embodiments of the present disclosure direct to a flexible device, comprising a flexible component layer, and a jamming device disposed proximate to the flexible component layer. The jamming device permits the flexible component layer to be bent in a first state. The jamming device is configured to resist bending of the flexible component layer in a second state.

Abstract: Non-adhesive articles include an elastomeric layer, where the elastomeric layer has a plurality of cuts arrayed in a pattern. The cuts are gaps, but the gaps are not visible to the naked eye when the article is in an unstressed state, and in a stressed state, at least some of the cuts become gaps that are visible to the naked eye. The gaps are perforations in the elastomeric layer and are apertures through which one can view through the elastomeric layer. The perforations indicate the presence of stress in the article, and the elastomeric layer has a lower effective modulus of elasticity in at least one axis than an identical elastomeric layer without the plurality of cuts.

The present disclosure also relates to methods of making and using these tension-activated, expanding articles.

Abstract: At least some embodiments of the present disclosure an electrostatic sheet jamming device comprising a first sheet having a first conductive layer, a first dielectric layer disposed adjacent to the first conductive layer, and a second sheet comprising a second conductive layer and disposed proximate to the first dielectric layer. The first dielectric layer is disposed between the first conductive layer and the second conductive layer. The first sheet and the second sheet are non-extensible and flexible, wherein the first sheet and the second sheet are slidable relative to each other in a first state. The first sheet and the second sheet are jammed with each other in a second state when a voltage is applied between the first conductive layer and the second conductive layer. In some embodiments, the applied voltage is less than or equal to a break-down voltage of air at a distance between the first conductive layer and the second conductive layer.

Abstract: The present disclosure provides adhesive mounting articles that permit sliding movement along a primary path, even while the article is fixed between a mounting object and a mounting surface. The adhesive articles can allow user precise control over the location and orientation of his or her mounting object, particularly frames.

Abstract: A substantially planar self-folding film assembly to generate a folded three-dimensional assembly. The assembly includes a flexible support substrate, adhesive elements, and folding members. The folding members include a base, a folding region, and a hinge adjacent each folding region attached at the base to the flexible support substrate by at least one of the adhesive elements. An array of polymer actuators is co-extensive, or shaped to be not co-extensive, with each of the flexible folding members. Upon activation by a patterned light to heat conversion layer, each polymer actuator is designed and configured to provide a displacement of the corresponding flexible folding member about each hinge.
