Offset Electrodes For Enhanced Neural Recording In Microchannels, Iian Black
FIU Electronic Theses and Dissertations
Microchannel electrodes have emerged in recent years as promising interfaces for recording signals in peripheral nerves. Unlike many technologies, microchannels maintain stable long-term connections and can record activity in individual or small groups of axons. Unfortunately, a traditional symmetrical mid-channel electrode configuration, designed to reduce noise artifacts, prevents microchannels from being used to distinguish between signals traveling in opposite directions. This is a profound limitation given that most nerves contain a mix of efferent and afferent axons and microchannels were initially conceived and later used as the basic building block in arrays designed to record bi-directional neural traffic in regenerated …

Research Opportunities for Engineering Undergraduates (ROEU) Program 2018-19
This project presents a corrosion-resistant and high capacity implantable TiN nanotube electrode to work as a neural probe. Smaller electrode size allows for reduced tissue damage while the nanopore morphology of the TiN gives a larger surface area and stability to the electrode. The electrode offers improved biocompatibility, reduced tissue damage, reduced cost, and increased usability over time.
