High Charge Storage Capacity Micro Electrode Array on a Wire for Implantable Neuromuscular Applications
In this paper, we demonstrate fabrication of high charge storage capacity microelectrode arrays (MEAs) on a thin gold wire, targeted towards implantable neuromuscular applications. The patterned wire is flexible and can be brought in contact with the targeted area with ease unlike traditional MEAs. The key contribution here is the demonstration of wire patterning, followed by electro chemical deposition of PEDOT (Poly 3,4-Ethylene Dioxy Thiophene)/Functionalized Multi walled Carbon Nanotubes (FMWCNT) hybrid nano-composite material in selected areas that resulted in biocompatible, high charge storage capacity (CSC) and lower electrode interface impedance MEA on wire.
