Description

The abstract claims the coating’s water resistance maintains electrical stability, yet hydrophobic surfaces could theoretically impair the ionic conductivity needed for high-quality neural recordings. The mechanism reconciling these seemingly opposing requirements remains unexplained and is critical for probe design optimization.
