Porous Gold Surfaces for Implantable Neural Electrodes
Neural electrodes used for measurements of action potentials in brain cells are often made of gold. These electrodes need to be suciently small to cover only one brain cell, but this induces the problem of increased impedance since impedance scales inversely with surface area. This means that if the surface area is too small, only noise will be measured. One way to overcome this problem is to try
