An integrated nanowire device includes a first array of nanowires having a first set of characteristics and a second array of nanowires having a second set of characteristics. A processor is electrical communication with the first and second arrays of nanowires receives the first plurality of charges and generate a processor signal therefrom. The second array of nanowires may be configured to produce a stimulation current in response to the processor signal. The first or second array may be used to generate power for operation of the device, or the arrays may function as a stimulator, sensor combination to enable the device to self-regulate based on localized responses to stimulation. The device may be implanted for use as a neural stimulator.

Integrated nanowire array devices for detecting and/or applying electrical signals to tissue

The present invention is a flexible circuit electrode array for stimulating neurons where the electrode are less than 20 &#x3bc;m in size and less than 60 &#x3bc;m apart. The array is preferably arranged in a hexagonal pattern to maximize electrode density, and longer in the horizontal direction to correspond to a normal visual scene. The array includes a polymer base layer, metal traces deposited on the polymer base layer, including electrodes suitable to stimulate neural tissue, and a polymer top layer deposited on the polymer base layer and the metal traces defining openings for the electrodes smaller than the electrodes to overlap the electrodes.
