Why Thin Film Platinum IDEs?

Interdigitated electrodes consist of an array of interlaced “fingers” that can provide enhanced sensitivity and responsiveness in electrochemical applications. Here’s why platinum is the ideal material:

  • Superior Conductivity: Platinum offers excellent electrical conductivity, ensuring efficient and accurate measurements.
  • Corrosion Resistance: It remains stable in harsh chemical environments, making it ideal for challenging applications.
  • Catalytic Properties: Platinum excels in electrochemical sensing due to its catalytic efficiency.
  • Thermal Stability: Platinum remains stable across a wide range of temperatures.
  • Biocompatibility: Suitable for biomedical applications due to its non-reactivity and compatibility with biological tissues.

Our Thin Film Fabrication Advantages

At Platypus Technologies, we pride ourselves on delivering high-quality thin film platinum electrodes fabricated via e-beam evaporation. This thin film coating method offers the following benefits:

  • High Purity (99.999%): We ensure consistent electrical properties by using only high-purity platinum, minimizing the impact of contaminants.
  • Low Surface Roughness: Our precise fabrication process provides a smooth surface essential for high-sensitivity applications, ensuring accuracy and repeatability.

Through our expertise in photolithography, wet etching and lift-off, we can fabricate custom patterns on the platinum thin films

Whether you need a specific layout design, or substrate material, we have the expertise and equipment to tailor the design to your specifications. We work with you to design the perfect layout, finger spacing, and substrate material to meet your needs.
