1. A method of forming a conductive diamond layer on a surface of a carbon fiber substrate, the carbon fiber substrate coated with the conductive diamond layer configured for use as a component of an electrode for neural stimulation and/or electrochemical sensing, the method comprising:
functionalizing at least a portion of the surface of the carbon fiber substrate with a functionalizing agent to provide a functionalized surface;
coating the functionalized surface with diamond seeds to form a diamond seed layer covalently bonded to the functionalized surface, wherein the functionalizing agent includes a chemical moiety for forming a covalent bond between the functionalized surface and the diamond seeds; and
using a diamond precursor, forming the conductive diamond layer via chemical vapor deposition on the diamond seed layer.
