Protective Coatings

Definition

Protective coatings are specialized materials applied to surfaces of neural interfaces to prevent degradation and maintain functionality over time. These coatings serve to shield the sensitive electronic components from biological factors such as moisture, ions, and proteins, which can lead to corrosion and loss of performance. The effectiveness of protective coatings is crucial for ensuring the long-term stability and reliability of neural interfaces, ultimately enhancing their viability in clinical applications.
