摘要： A parylene microcapillary is manufactured by drawing a polyethylene carbonate (PEC) fiber from a 0° C. solution of 12-25% PEC in chloroform to create a PEC fiber that has a constant diameter over several centimeters. Parylene is deposited in a chamber over the PEC fiber, and then the coated PEC fiber is heated above 180° C. This heating melts and decomposes the PEC fiber such that it self-expels from the coating, leaving a microcapillary. The self-expulsion allows for meters-long lengths of microcapillaries. Alternatively, a serpentine fiber channel of PEC is created by deposition, photolithography, and etching within a sandwich of parylene. It is heated above 180° C. to expel the PEC leaving a hollow channel within a mass of parylene. The resulting microcapillaries may have residues of cyclic ethylene carbonate remaining from the decomposed PEC.

摘要： The present disclosure relates to a microvalve using surface tension, a microfluidic chip including same and a method for manufacturing same. More particularly, the present disclosure relates to a microvalve using surface tension, a microfluidic chip including same and a method for manufacturing same, wherein the microvalve can be manufactured through a simple process and the microvalve and a coaxial sample channel are not separated, and thus the microvalve may be easily installed not only in an existing quadrangular channel but also in the coaxial channel so as to control the flow and amount of a microfluid (sample).

摘要： Methods and devices for tissue remodeling and repair of collagenous tissues, including tendons, ligaments, and bone, as well as scalable connective tissue manufacturing, are provided. Collagen fibers are assembled by extensional strain-induced flow crystallization of collagen monomers. Extensional strain also drives the fusion of already formed short collagen fibrils to produce long-range, continuous fibers. Wearable devices for controlled tissue remodeling and wound healing deliver a tissue remodeling solution to a tissue repair site. The remodeling solution, together with appropriate application of strain to the tissue remodeling site, accelerate healing, prevent injury, and reduce scar formation.

摘要： A direct write dispensing nozzle assembly and method of forming traces and twisted pairs via direct write dispensing. The method includes dispensing conductive material via an inner nozzle so as to form a conductive core. Non-conductive material may be dispensed via a peripheral nozzle surrounding the inner nozzle so as to form a non-conductive casing surrounding the conductive core. The first conductive core and the non-conductive casing may then be deposited on a substrate or other surface. The trace may be positioned on the substrate such that the non-conductive casing contacts a previously deposited trace. An additional conductive core may be dispensed within the non-conductive casing and the direct write dispensing nozzle assembly may be rotated so as to form a twisted pair.

摘要： Methods for preparing and orientating nanofibers and a composite material including the same. Some methods for preparing a composite material with orientated nanofibers may include providing a nanoporous material; dissolving a natural or synthetic polymer, —in a solvent; pressing or drawing the polymer solution through pores of the nanoporous material whereby nanofibers are formed within said material; mixing the nanofibers with a matrix material; orientating or partially orientating the nanofibers within the matrix material by applying an electric and/or magnetic field; depositing the nanofibers-matrix mixture with the orientated or partially orientated nanofibers onto a substrate surface. The nanofibers may be oriented locally different in various areas/layers of the composite material, resulting in a composite material with locally independent mechanical properties.

摘要： A method for producing a polymer composite fiber comprised of a polymer matrix with filaments incorporated therein whose lengthwise dimensions are substantially oriented with the axial dimension of the composite fiber, the method comprising subjecting a melt comprised of a polymer matrix and filaments to an extrusion process in which the melt is extruded into a fibrous form in the absence of screw extruders and in the substantial absence of shear forces that result in breakage of the filaments, followed by cooling and solidification of the extruded melt to provide the polymer composite fiber. Integration of these polymer composite fibers with additive manufacturing technologies, particularly rapid prototyping methods, such as FFF and 3D printing, are also described. The resulting polymer composite fibers and articles made thereof are also described.

摘要： Surgical sutures are provided. In general, the surgical sutures can include a plurality of directional indicators that each visually indicate a same direction, e.g., a direction toward one free end of the suture. The directional indicators can be configured to indicate a position of the suture relative to a patient and/or other medical device(s). The directional indicators can be a function of the suture itself so as to be an integral part thereof. In other words, threads, also referred to as “strands,” that form the suture can define the directional indictors. The suture can be braided using threads of two different colors so as to form the directional arrows as an integral part of the suture when the suture is braided in manufacturing of the suture.
