Neural interfaces are connections linking the neuronal systems with electro-mechanical systems for information exchange. Microelectrodes of various designs have been fabricated utilizing both metallic and non-metallic materials so that they can be employed as neural interfaces. Recent studies have shown that the performance of microelectrodes can be enhanced significantly through structure controlling, surface chemistry and biotechnology. This review highlights the challenges including invasiveness, stability and selectivity associated with the employment of common electrodes as interfaces for neural recording and stimulation. It also includes controlling of electrode material and geometry as engineering solutions for the aforementioned challenges. Due to their high surface area, small size and high electrochemical properties, nanostructured electrodes show promise as electrodes that could be employed as neural interfaces for stable signal recording and stimulation. We hope this work will provide a concise picture of the evolution and the progress of current neural interfaces technology, the development of which is still in progress.
