Patent number: 8941390Abstract: A test system for medical devices that does not require physical contact with an electrical site along a conductive path is described. Not having to physical contact an electrical site while performing an electrical continuity test avoids potential damage to the site. The test system includes a fluidic channel that dispenses an electrolytic solution onto a first electrical site on the conductive path. A light source irradiates the first site to thereby induce a photoelectrochemical (PEC) effect at an interface thereof. The PEC effect produces a change in both the potential (i.e., voltage) and current carrying ability in the conductive path. That voltage or current is measured at a second site to determine whether there is electrical continuity or discontinuity between the sites on the conductive path.Type: GrantFiled: March 1, 2013Date of Patent: January 27, 2015Assignee: NeuroNexus Technologies, Inc.Inventors: John P.

Publication number: 20130066182Abstract: Improved low-cost, highly reliable methods for increasing the electrochemical surface area of neural electrodes are described. A mono-layer of polymeric nanospheres is first deposited on a metallization supported on a dielectric substrate. The nanospheres self-assemble into generally repeating lattice forms with interstitial space between them. Then, the geometric surface area of the metallization material is increased by either selectively etching part-way into its depth at the interstitial space between adjacent nanospheres. Another technique is to deposit addition metallization material into the interstitial space. The result is undulation surface features provided on the exposed surface of the metallization. This helps improve the electrochemical surface area when the treated metallizations are fabricated into electrodes.Type: ApplicationFiled: September 14, 2012Publication date: March 14, 2013Applicant: NeuroNexus Technologies, Inc.Inventor: John P. Seymour
