Latest Patents

Sang Heon Lee's latest patents include the "Addressable Vertical Nanowire Probe Arrays and Fabrication Methods." This invention features a nanowire probe sensor array that consists of a substrate with a metal pattern. The array of semiconductor vertical nanowire probes extends away from the substrate, allowing for individual electrical addressing through the metal pattern. The metal pattern is insulated with dielectric material, ensuring the base and stem portions of the nanowires are also insulated. The fabrication process involves patterning metal connections on a substrate, bonding a semiconductor substrate to the metal pattern, and etching the semiconductor substrate to form the neural nanowire probes.

Another notable patent is the "Method for Forming a Multielectrode Conformal Penetrating Array." This invention includes a flexible plastic substrate that conforms to cortical tissue. A plurality of penetrating semiconductor microelectrodes extends from the surface of the flexible substrate, designed to penetrate cortical tissue effectively. The electrode lines are encapsulated within the flexible substrate and are electrically connected to the penetrating semiconductor microelectrodes, which feature pointed metal tips. The fabrication method allows for the creation of stiff penetrating electrodes on a highly flexible substrate, ensuring reliable electrical connections.
