A lithographically fabricated electrode comprises a continuous metal film; and a discontinuous metal film. The discontinuous metal film has a first edge proximal to the continuous metal film, and a second edge distal the continuous metal film.

Electrical contacts for nanoparticle networks

Disclosed herein is a neuromorphic percolating network (). The network comprises a substrate () having at least two electrical contacts (A,B); a plurality of nanoparticles () distributed on the substrate (), at least some of the nanoparticles positioned between at least two of the at least two electrical contacts, the surface coverage of the nanoparticles within a tolerance of a percolation threshold; and at least one memristive element () located at least partially in a gap between nanoparticles, or groups of nanoparticles, that are not otherwise directly connected to each other, the memristive element(s) at least partially providing at least one persistent pathway () of increased activity. Disclosed herein are methods for fabricating a neuromorphic percolating network or component thereof, and neuromorphic percolating networks formed by such methods.

Neuromorphic network

A neuro-electronic interface device has a micro-electrode electrically connected to an interconnect that has scaling gradients between 1.1 and 1.9 over a scaling range of at least one order of magnitude. The device preferably has an array of such fractal interconnects in electrical contact with an array of micro-electrodes. Such fractal interconnect arrays may be components of implants including a retinal implant device having an array of photodetectors in electrical contact with the array of micro-electrodes. The interconnects may be fabricated by forming nanoscale particles and depositing them onto a non-conductive surface that is smooth except for electrodes which serve as nucleation sites for the formation of fractal interconnect structures through diffusion limited aggregation.

Fractal interconnects for neuro-electronic interfaces and implants using same

The invention relates to a method of forming a conducting nanowire between two contacts on a substrate surface wherein a plurality of nanoparticles is deposited on the substrate in the region between the contacts, and the single nanowire running substantially between the two contacts is formed by either by monitoring the conduction between the contacts and ceasing deposition at the onset of conduction, and/or modifying the substrate to achieve, or taking advantage of pre-existing topographical features which will cause the nanoparticles to form the nanowire. The resultant conducting nanowires are also claimed as well as devices incorporating such nanowires.
