Thin-Film Microfabricated Electrodes

Thin-Film Microfabricated Electrodes

Thin-Film Microfabricated Electrodes represent a powerful class of research-grade electrochemical sensors engineered using high-resolution thin-film deposition techniques. Fabricated on glass wafers and encapsulated with SU-8 or PI resins, these sensors feature micro- to sub-millimetre precision, enabling reliable and reproducible performance in advanced analytical applications.

These electrodes are typically constructed with gold or platinum thin films (≈150 ± 15 nm thickness) deposited on glass substrates via photolithography and vacuum-based deposition processes. Their compact form factor (typically 10 × 6 × 0.7 mm) and integrated electrochemical cells (2 or 3.5 mm Ø) allow for ultra-low sample volume requirements—just 1–10 µL.

Thin-film electrodes are widely used in microfluidic platforms, biosensors, electrochemical impedance spectroscopy (EIS), lab-on-a-chip systems, and diagnostic devices. The integration of reference and auxiliary electrodes on the same chip minimises alignment issues and streamlines experimental workflows. Optional configurations include single-electrode (SE), interdigitated electrodes (IDE), microelectrode arrays (MEA), interdigitated arrays (IDA), and radial ring geometries (IDRA)—each suited for specific applications like redox cycling, conductivity measurement, or multiplexed biosensing.

ScienceGears supplies these sensors throughout Australia and New Zealand, offering compatibility with MicruX’s All-in-One (AIO) electrochemical platforms, including flow-cell and batch-cell modes. Researchers can easily interface these sensors with potentiostats using TF-CABLE or IDE-CABLE connectors, ensuring plug-and-play convenience across laboratory setups.

Features such as high sensitivity, precision patterning, reusability, and minimal pre-cleaning make thin-film electrodes an essential tool in academic research, biomedical development, and analytical chemistry.

Whether you're designing next-generation biosensors or performing impedance analysis in confined volumes, ScienceGears offers tailored access to the full MicruX thin-film sensor range for research institutions across Australasia.
