  • Microdevices and methods of manufacture
    Patent number: 9890259
    Abstract: Illustrative embodiments of microdevices and methods of manufacturing such microdevices are disclosed. In at least one illustrative embodiment, one or more microdevices may be formed on a substrate, with each of the one or more microdevices comprising a body micromachined from a continuous film formed on the substrate, the continuous film having a controlled microstructure of cellulose nanocrystals (CNC).
    Type: Grant
    Filed: May 1, 2016
    Date of Patent: February 13, 2018
    Assignees: Auburn University, Clemson University
    Inventors: William Robert Ashurst, Virginia A. Davis, Christopher L. Kitchens

  • Microdevices and methods of manufacture
    Patent number: 9353313
    Abstract: Illustrative embodiments of microdevices and methods of manufacturing such microdevices are disclosed. In at least one illustrative embodiment, a method of manufacturing one or more microdevices may include forming a liquid dispersion containing cellulose nanocrystals (CNC), depositing the liquid dispersion containing the CNC on a substrate, drying the liquid dispersion containing the CNC to form a solid film on the substrate, where the liquid dispersion contains a sufficient concentration of CNC to form a continuous solid film having a controlled microstructure, and processing the solid film to form the one or more microdevices on the substrate.
