  • CONFORMABLE NEURAL INTERFACE DEVICE WITH HYDROGEL ADHESION AND METHODS OF USING THE SAME
    Publication number: 20210268268
    Abstract: Disclosed are highly compliant bioelectronic neural interface devices with hydrogel adhesion. Example devices include adhesion-promoting functional groups that facilitate enhanced electrical contact with the nerve without the need for continuous application of pressure. A transfer process may be used to fabricate the device using a sacrificial material (e.g., polyacrylic acid (PAA)) that has tunable solubility in aqueous media, helping avoid the need for harsher release chemicals that may affect the properties of the hydrogel. The transfer process also helps achieve electrode contacts that are flush with a surface of the device and facilitate more intimate contact with the nerve. A gradual change in Young's modulus from a stiff contact pad region to a more compliant electrode contact region may be achieved via a varied amount of an epoxy-based material (such as SU-8 ) and with silicone-based material (such as polydimethylsiloxane (PDMS)) to encapsulate the device cable.

  • 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.
