For electrochemical sensing applications, working electrodes typically require a minimum electrical conductivity of around 1 to 10 mS/cm to ensure effective performance.

While there isn't a strict, universally applicable minimum conductivity value, a generally accepted guideline is that the working electrode should have a conductivity of at least 1-10 mS/cm. This ensures that the electrode can effectively transfer electrons between the analyte solution and the external circuit, which is crucial for accurate electrochemical sensing.
