Abstract
A brain implant system consistent with embodiments of the present invention includes an electrode array having a plurality of electrodes for sensing neuron signals. A method for manufacturing the electrode array includes machining a piece of an electrically conductive substance to create a plurality of electrodes extending from a base member. Each electrode also has a corresponding base section. A nonconductive layer is provided around at least a portion of the base section of each electrode to support the plurality of electrodes. The base section of the electrodes are then cut to separate the base member from the plurality of electrodes supported by the nonconductive support layer. The present invention also includes a complete brain implant system using the above electrode array.
