Abstract

In vivo implantation of microelectrodes opens the door to studying neural circuits and restoring damaged neural pathways through direct electrical stimulation and recording. Although some neuroprostheses have achieved clinical success, electrode material properties, inflammatory response, and glial scar formation at the electrode-tissue interfaces affect performance and sustainability. Those challenges can be addressed by improving some of the materials' mechanical, physical, chemical, and electrical properties. This paper reviews materials and designs of current microelectrodes and discusses perspectives to advance neuroprosthetics performance.

期刊介绍： Bioactive Materials is a peer-reviewed research publication that focuses on advancements in bioactive materials. The journal accepts research papers, reviews, and rapid communications in the field of next-generation biomaterials that interact with cells, tissues, and organs in various living organisms. The primary goal of Bioactive Materials is to promote the science and engineering of biomaterials that exhibit adaptiveness to the biological environment. These materials are specifically designed to stimulate or direct appropriate cell and tissue responses or regulate interactions with microorganisms. The journal covers a wide range of bioactive materials, including those that are engineered or designed in terms of their physical form (e.g. particulate, fiber), topology (e.g. porosity, surface roughness), or dimensions (ranging from macro to nano-scales). Contributions are sought from the following categories of bioactive materials: Bioactive metals and alloys Bioactive inorganics: ceramics, glasses, and carbon-based materials Bioactive polymers and gels Bioactive materials derived from natural sources Bioactive composites These materials find applications in human and veterinary medicine, such as implants, tissue engineering scaffolds, cell/drug/gene carriers, as well as imaging and sensing devices.
