Epigem has developed a unique method for the manufacture of customisable fine-line microcircuitry, suitable for a wide range of applications.

The conducting microelectrode elements, typically about 5um thick and anything down to about 15 um wide, are embedded in a transparent resin layer. This is then transferred onto either a rigid or a flexible carrier surface.

Key Features

Planar top surface – conducting element coplanar with exposed resin surface

Conductor material: nickel with an optional gold ‘flash’

Conductor thickness typically 5 um

Track gaps and widths down to around 15 um

Flexible (typically PET) or rigid (typically acrylic) substrates

Overall circuit dimensions up to approx. 300 mm square

More About Microelectrodes

The microelectrodes can be combined with our microfluidic devices to deliver embedded patterned circuitry designed to interact with and influence the flow of liquids within the devices – see Electrical-microfluidic Hybrid Devices.

Microcircuit-based components and devices are supplied to customers globally and incorporated by them into a range of analytical and test equipment.

Typical applications of our microelectrode products include:

  • Interdigitated electrodes for DEP (dielectrophoresis) microfluidic components
  • Transparent electrode systems for microscopy-based biomedical analysis
  • Transparent conducting elements (with superior properties to ITO) for photovoltaic cells

We can manufacture components in both small volumes (for development projects and prototyping) and higher numbers to support full product manufacture and sales. Our engineers have many years’ experience in the design of circuitry for different applications and will be happy to discuss all relevant options for your own application.
