Cylindrical microelectrode array for neural stimulation and recording
A cylindrical microelectrode array having an elongated cylindrical core, and a multilayer structure conformally folded around and affixed to the cylindrical core so as to extend between opposite ends of the core. The multilayer structure has integrated sections including an electrode section with electrodes exposed through electrically insulating layers, a connector section with conductive bond pads for interfacing with external electronics, and a cable section with conductive traces encapsulated in electrically insulating layers and which connect between the electrodes and their corresponding bond pads. The array may be fabricated using a planar multilayer structure having the electrode, connector, and cable sections, and conformally folding the multilayer structure around and affixing to the cylindrical core. The cable section in particular may be conformally coiled around and affixed to the cylindrical core so that the electrical conduits helically extend between the connector and electrode sections.
