Bipolar - Platinum Iridium

Platinum-Iridium alloy is considered by many to be the “gold standard” for chronic recording and microstimulation due to its excellent electrochemical and mechanical characteristics.

Advantages

  • Platinum-Iridium possesses lower concomitant impedance, higher charge transfer capacity, and improved electrochemical stability compared to tungsten and stainless steel.
  • Offers excellent and versatile microstimulation performance, allowing safe stimulation to be performed with small probe sizes.
  • Iridium content of alloy greatly improves mechanical hardness and stiffness, providing electrodes with a degree of bend resistance that approaches tungsten.

Disadvantages

  • Greater cost than tungsten and stainless steel, making it less appropriate for acute recording or non-intensive chronic recording.
  • Can be vulnerable to corrosion and dissolution with some intensive stimulation protocols.
