  • Patent number: 11741854
    Abstract: An organ model comprises a polymer body formed from one or more selectively deposited substructures of a printable polymer-based ink composition, wherein the one or more selectively deposited substructures form a printed geometrical structure that corresponds to at least a portion of an anatomical structure of an organ, wherein a formulation of the printable polymer-based ink is selected such that the printed geometrical body has one or more material properties that match or substantially match one or more corresponding tissue material properties of an organ tissue, and an electronic device integrated onto a surface or into a structure of the printed geometrical structure.
    Type: Grant
    Filed: October 17, 2018
    Date of Patent: August 29, 2023
    Assignee: Regents of the University of Minnesota

  • Patent number: 9499686
    Abstract: ‘Green’ composites are fabricated using resins, such as soy-based resins, and reinforced with crystalline high strength bacterial cellulose (BC) fibers. Bacterial cellulose is produced by providing a bacterial cellulose-producing bacterium such as Acetobacter xylinum; providing an inexpensive bacteria nutritional medium; culturing the bacterium in the bacteria nutritional medium under conditions to produce bacterial cellulose; and isolating bacterial cellulose produced by cultured bacteria from the bacteria nutritional medium. The bacteria nutritional medium comprises an inexpensive carbon source that is a plant-based seed extract. The seed extract is derived from a plant-based seed comprising soluble sugars.
