The market for transparent conductive films is expected to increase to $3.39 billion in 2020


  • New approach to producing conductive transparent films by inkjet printing
  • Alternative to brittle indium tin oxide (ITO) and fluorinated tin oxide (FTO) layers
  • Provides simple, low-cost alternative to current processes

Our Innovation

Novel method for inkjet printing transparent layer composed of rings of conductive nanoparticles for use in optoelectronic and electronic devices




Key Features

  • Can be used on a variety of  substrates, both flexible and rigid
  • Suitable for many optoelectronic devices that require transparent conductors
  • Allows transmittance of visible, UV, IR, and NIR wavelengths
  • Not brittle like ITO – better for flexible electronics
  • A simple printing process that can use a variety of conductive inkjet inks

Development Milestones

Seeking funding for utilization in optoelectronic and electronic devices , and for up-scaling of printable surface area


The Opportunity

  • Increasing numbers of optoelectronic devices such as flexible displays for touch screens, smart windows require transparent conductors that can be fabricated by low cost processes.
  • The process requires very little amount of material, and is performed by a direct printing process which is suitable for a variety of substrate and at large format.
