Implantable Neural Interfaces and Electrode Materials for Brain and Spinal Cord Stimulation
This community develops the electronic hardware and electrode materials used to record signals from, and deliver electrical stimulation to, the brain and spinal cord. The work focuses on creating durable, biocompatible interfaces that can interact with neural tissue for therapeutic and diagnostic purposes.
The research centers on the engineering of microelectrode arrays, flexible thin films, and conductive polymers such as PEDOT:PSS and iridium oxide. These materials are designed to improve the stability and signal quality of neural recording and stimulation leads. Applications include deep brain stimulation for Parkinson's disease, spinal cord stimulation for pain management, and cochlear implants. The work also addresses the fabrication of field-effect transistors and carbon fiber electrodes to enhance the sensitivity of neural interfaces. Recent efforts emphasize the integration of these components into wireless, battery-less implants and scalable manufacturing processes for high-density cortical arrays.
The community is most heavily concentrated in research tracked for Iridium, accounting for 2.9% of all Iridium-related papers, with 1,073 papers in this group. It also contributes to research on Lead, representing 0.3% of that element's tracked literature with 309 papers.
The community comprises 6,836 papers, with the highest publication volume in the Journal of Neural Engineering, bioRxiv, and Sensors and Actuators B Chemical.
Recent work includes the development of ultra-high-density Neuropixels probes for neuronal recording, minimally invasive implantation of scalable high-density cortical microelectrode arrays, and the use of PEDOT:PSS conducting eutectogels for enhanced electrical recording and stimulation in implantable neural interfaces.
