Patents by Inventor Rein V. Ulijn

Rein V. Ulijn has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • WATER-RESPONSIVE MATERIALS AND USES THEREFOR
    Publication number: 20210214469
    Abstract: A rotary engine that generates electricity using differences in relative humidity. A water-responsive material expands and contracts as water evaporates which drives the rotation of two wheels. The rotary motion drives an electrical generator which produces electricity. In another embodiment, the water-responsive material is used to actuate an artificial muscle of a robotic device.
    Type: Application

  • Self-assembling peptide polymer
    Patent number: 11021516
    Abstract: A self-assembling peptide is provided that is enzymatically oxidized to form a polymeric pigment. The monomeric peptide has three amino acids (tyrosine (Y), one phenylalanine (F), and one aspartic acid (D) or one lysine (K)) and, following self-assembly and treatment with a tyrosinase enzyme oxidizes and polymerizes into a material with predetermined properties.
