Latest Patents

Gutian Xiao holds a patent for a "Conformable neural interface device with hydrogel adhesion and methods of using the same." This patent discloses highly compliant bioelectronic neural interface devices that utilize hydrogel adhesion. The devices feature adhesion-promoting functional groups that enhance electrical contact with nerves without requiring continuous pressure application. The fabrication process involves a transfer method using a sacrificial material, such as polyacrylic acid (PAA), which has tunable solubility in aqueous media. This approach avoids harsher release chemicals that could compromise the hydrogel's properties. The design also allows for electrode contacts that are flush with the device surface, promoting intimate contact with the nerve. Additionally, a gradual change in Young's modulus is achieved from a stiff contact pad region to a more compliant electrode contact region through the use of varied epoxy-based materials and silicone-based encapsulation.
