Tungsten

Tungsten is a versatile and widely-used microelectrode material that offers a good balance between performance and cost.

Advantages

  • Extremely strong and stiff metal provides probes with exceptional rigidity.
  • Great for acute and chronic recording due to biocompatibility and lower cost.
  • High corrosion resistance offers consistent long-term performance.

Disadvantages

  • Does not provide the same degree of electrochemical performance or stability as platinum-iridium alloy, making it a poor alternative for microstimulation.
  • Lower charge transfer capacity of tungsten will result in larger, potentially unsafe interfacial potentials when applying the same stimulation current as to a platinum-iridium electrode.
  • Certain pH or stimulation conditions can lead to tungsten corrosion.
Tungsten Tip Profile

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.

Blunted Tip Profile

B - BLUNTED TIP PROFILE

Our blunted electrodes are engineered to have a more rounded, bullet-shaped tip. For many applications the blunted tip can offer superior stimulation performance.
