Neural stimulation and recording electrodes.
Electrical stimulation of nerve tissue and recording of neural electrical activity are the basis of emerging prostheses and treatments for spinal cord injury, stroke, sensory deficits, and neurological disorders. An understanding of the electrochemical mechanisms underlying the behavior of neural stimulation and recording electrodes is important for the development of chronically implanted devi...
متن کاملNeural Interfaces for Intracortical Recording: Requirements, Fabrication Methods, and Characteristics
Implantable neural interfaces for central nervous system research have been designed with wire, polymer, or micromachining technologies over the past 70 years. Research on biocompatible materials, ideal probe shapes, and insertion methods has resulted in building more and more capable neural interfaces. Although the trend is promising, the long-term reliability of such devices has not yet met t...
متن کاملUltraflexible organic amplifier with biocompatible gel electrodes
In vivo electronic monitoring systems are promising technology to obtain biosignals with high spatiotemporal resolution and sensitivity. Here we demonstrate the fabrication of a biocompatible highly conductive gel composite comprising multi-walled carbon nanotube-dispersed sheet with an aqueous hydrogel. This gel composite exhibits admittance of 100 mS cm(-2) and maintains high admittance even ...
متن کاملFluidic Microactuation of Flexible Electrodes for Neural Recording.
Soft and conductive nanomaterials like carbon nanotubes, graphene, and nanowire scaffolds have expanded the family of ultraflexible microelectrodes that can bend and flex with the natural movement of the brain, reduce the inflammatory response, and improve the stability of long-term neural recordings. However, current methods to implant these highly flexible electrodes rely on temporary stiffen...
متن کاملLong-Term Recording Properties of Longitudinal Intra-Fascicular Electrodes
Longitudinal intra-fascicular electrodes (LIFE) have been shown to be a potentially useful neural interfacing platform for basic electrophysiology and functional electrical stimulation. However, few studies have attempted to characterize their long-term recording properties. The objective of the present work was to investigate qualitative and quantitative changes in electroneurogram (ENG) signa...
