A carbon fiber implantable probe, a method of manufacturing the carbon implantable probe, and a method of implanting the probe in an implantation site, such as a nerve. The carbon fiber implantable probe includes a flexible probe body, a carbon fiber microarray (CFMA) composing one or more carbon fiber electrodes at least partially embedded in the flexible probe body, and a signal conductor connected to the one or more carbon fiber electrodes of the CFMA. In one example, the CFMA includes carbon fiber electrodes having conductive carbon cores partially surrounded by an insulative coating. The combination of the CFMA with the flexible probe body, made of silicone rubber for example, can improve implantation processes.

A mote includes an optical receiver that wirelessly receives a power and data signal in form of NIR light energy within a patient and converts the NIR light energy to an electrical signal having a supply voltage. A control module supplies the supply voltage to power devices of the mote. A clock generation circuit locks onto a target clock frequency based on the power and data signal and generates clock signals. A data recovery circuit sets parameters of one of the devices based on the power and data signal and a first clock signal. An amplifier amplifies a neuron signal detected via an electrode inserted in tissue of the patient. A chip identifier module, based on a second clock signal, generates a recorded data signal based on a mote chip identifier and the neuron signal. A driver transmits the recorded data signal via a LED or a RF transmitter.

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.
