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.
A - STANDARD TIP PROFILE
Our standard tip profile features a sharp yet robust point that offers versatile performance and an effective balance between penetration and durability.
