The present disclosure provides a method of fabricating an implantable micro-component electrode. The method includes disposing an electrically non-conductive material directly onto a surface of an electrically conductive carbon fiber core to generate an electrically non-conductive coating on the electrically conductive carbon fiber core, and removing a portion of the electrically non-conductive coating to expose a region of the electrically conductive carbon fiber core. The micro-component electrode has at least one dimension of less than or equal to about 10 &#x3bc;m.

Implantable micro-component electrodes

The present disclosure provides robust implantable micro-component electrodes that can be used in a variety of medical devices. The medical device may be a neural probe that can monitor or stimulate neural activity in an organism's brain, spine, nerves, or organs, for example. The micro-component electrode has a small physical profile, with ultra-thin dimensions, while having high strength and flexibility. The micro-electrode has an electrically conductive core material, e.g., carbon. The surface of the core material includes one or more electrically conductive regions coated with an electrically conductive material and one or more non-conductive regions having an electrically non-conductive biocompatible polymeric coating. Implantable devices having such micro-components are capable of implantation in an organism for very long durations.
