Abstract:
Disclosed is a gas generating polymer compound that when irradiated with light or other radiation sources makes a solid to gas phase transition due to chemically catylized degradation, irradiative degradation or both. This provides a low cost, stable and easily manufactured means. of gas production. Also disclosed are possible uses for the gas generator such as a low cost micro thruster.
Abstract:
An actuator housing unit for a system of layered surfaces, comprising an activated primary surface having a physical shape capable of change when activated by an electrical, chemical, or light stimulus, to expand and exert force or pressure or contract and remove force or pressure, upon activation or deactivation, to move or keep matter within the housing by direct or indirect contact.
Abstract:
The electrically connectable tile module includes a porous substrate having a top side, a bottom side, and at least two side edges. At least one connector is integrated into the porous substrate allowing adjoining electrically connectable tile modules to be electrically connected to the porous substrate. At least one electrical element is disposed over the top side of the porous substrate and electrically connected to the at least one connector.
Abstract:
A woven fabric formed of fabric fibers or threads coated with a hydrogel, wherein said hydrogel is not crosslinked or is partially crosslinked to the fabric fibers or thread, wherein the hydrogel has a number of excess reactive molecules that are available for a reaction with one or more molecules solvated in an aqueous solution, and wherein the reactive molecules of the hydrogel can reversibly bond with the molecules solvated in an aqueous solution, such that the reactive molecules of the hydrogel attract the molecules solvated in aqueous solution when the hydrogel coated fabric substrate is exposed to an aqueous solution.
Abstract:
Described is a super elastic epoxy hydrogel that is easy to manufacture and can be engineered for various performance enhancements of the polymer. Also described are methods of enhancing the performance of this hydrogel and other hydrogels. Various polymer hydrogel composites, structures, and their uses are included, such as the actuator element comprising the hydrogel of the invention depicted in FIG. 2.
Abstract:
Biocompatible, triggerable degradation, polymerizable hydrogels, uses and delivery devices are disclosed. These hydrogels are at least substantially water soluble macromers, having a variety of uses especially for ocular therapy. The macromers include at least one water soluble region, at least one region which is degradable via a triggering event, usually by hydrolysis, and at least two free radical-polymerizable regions. The regions can, in some embodiments, be both water soluble and trigger able degradable. The macromers are polymerized by exposure of the polymerizable regions to free radicals generated by photosensitive chemicals and dyes. An advantage of these polymer hydrogels is that they can be polymerized rapidly in an aqueous surrounding. Precisely conforming, semi-permeable, biodegradable films or membranes can thus be formed on tissue in situ to serve as biodegradable barriers, as carriers for living cells or other biologically active materials, and as surgical adhesives for the eye.
