Development and biological assessment of optical-electrode ‘optrode’ transducers for recording electrical activity in the body.

Body Text

Competitive advantage

  • Multi-disciplinary team working at the interface of biology and engineering
  • A patent portfolio covering industrial and biomedical aspects of technology


  • MOAs overcome the limitation of current recording systems by using light to carry bioelectric signals. This work will lead to the next generation of brain-computer interfaces.
  • It enables high-density, high channel count recording from neural and cardiac tissue
  • Application for brain-machine interfacing and prostheses
  • Application for cardiac diagnostic systems
  • The underlying technology of MOAs can also be applied in acoustic sensing networks to have many applications including:
  • Ocean monitoring (distributed sonars)
  • Mineral prospection (geoseismic exploration)
  • Environmental protection (leak detection in water distribution networks)

Successful applications

  • Demonstrated ability to map electrical activation in hearts in animal models
  • Demonstrated ability to record peripheral nerve responses in animal models

Capabilities and facilities

  • Biomedical microfabrication facility
  • A range of electrophysiology, animal surgery, and microscopy setups for biological assessment of technology
  • Access to engineers and infrastructure at the Australian National Fabrication Facility
