Patent number: 11692855Abstract: In some examples, a microstructured fiber comprises a cladding material surrounding at least one core material, wherein the at least one core material comprises an array of discrete devices contacted in parallel. A method of producing a microstructured fiber may include 3D-printing a fiber preform, thermally drawing the fiber preform into a fiber that preserves the cross-sectional geometry of the fiber preform, and axially patterning the fiber into a microstructured fiber comprising an array of discrete devices contacted in parallel. In some embodiments, microstructured fibers may be integrated into a sensory textile that includes at least one of an electrooptic portion, a sonar portion, a magnetic gradiometer portion, and a piezogenerating portion. In some embodiments, microstructured fibers may be formed into an in-fiber integrated quantum device circuit or an in-fiber ion trap.Type: GrantFiled: April 23, 2021Date of Patent: July 4, 2023Assignee: THE TRUSTEES OF INDIANA UNIVERSITYInventors: Alexander Gumennik, Mengxin Zheng, Camila Faccini de Lima, Veda Narayana Koraganji

Publication number: 20220401616Abstract: Technologies for fibers with nanotechnology is disclosed. In the illustrative embodiment, a preform is 3D printed with one or more sacrificial cores and one or more hollow channels. The preform is drawn into a fiber, and one or more metal core(s) is inserted into the hollow channel during the fiber draw. The fiber is then heated, breaking up the sacrificial cores into balls through capillary action. The fiber can be etched, exposing the balls made up of the sacrificial cores. The balls can be selectively etched, exposing the metal core(s) of the fiber. Additional embodiments are disclosed.Type: ApplicationFiled: November 2, 2020Publication date: December 22, 2022Inventors: Chandan K. SEN, Alexander GUMENNIK, Louis Alexandre VAN DER ELST, Merve GOKCE KURTOGLU

Publication number: 20210330864Abstract: A method of producing bioengineered tissue includes coating a microstructured fiber with a bioink containing a plurality of living cells. The microstructured fiber is embedded with microfluidic channels defining periodic outlet apertures, a plurality of ultrasonic transducers, at least one chemical sensor, and at least one temperature sensor. The method further includes applying the coated fiber to an anatomic model of an organ. The microfluidic channels and outlet apertures of the fiber are configured to function as an artificial blood-vessel system to the bioengineered tissue, thereby supplying building material for the proliferation of the plurality of living cells, and allowing the bioengineered tissue to mature into functional tissue.Type: ApplicationFiled: April 23, 2021Publication date: October 28, 2021Inventors: Alexander GUMENNIK, Louis Alexandre van der ELST, Merve Gokce Kurtoglu

Patent number: 10406723Abstract: A fiber is provided that has been thermally drawn from a fiber preform, having a longitudinal-axis length and including at least one core that has a longitudinal core axis parallel to the longitudinal axis and internally disposed to at least one outer fiber cladding material layer along the fiber length. The fiber is fed through a localized heating site having a heating site temperature, T, that is above a melting temperature of the fiber core, with a feed speed, ?f, that melts a portion of the fiber core at the heating site, causing molten droplets to pinch off of fiber core material, one droplet at a time, with a time period of molten droplet formation set by the fiber feed speed, ?f. The fiber is fed through the localized heating site to move the molten droplets out of the heating site and solidify the molten droplets into solid in-fiber particles.Type: GrantFiled: March 13, 2014Date of Patent: September 10, 2019Assignees: University of Central Florida Research Foundation, Massachusetts Institute of TechnologyInventors: Yoel Fink, Ayman F.
