Abstract: 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.

Abstract: 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 μm.
