Lowering the cost of LED lighting

Our researchers are in a consortium solving problems that limit take-up of LED lights. Read more »

The Centre for Advanced Sensor Technologies was founded in 2006 and brings together expertise in microelectronics, optoelectronics and novel materials. Advanced sensors have wide-ranging impact in everyday life and are used to:

  • build new energy efficient lighting systems
  • develop cheap, fast and easy medical diagnostics, such as blood tests
  • Monitor pollution
  • measure cell damage in accident victims
  • make manufacturing more efficient.

The Centre's interdisciplinary research focuses on highly accurate sensors, devices and related technologies, including:

  • electronic circuit and systems
  • wide bandgap semiconductors
  • LEDs
  • devices for medical applications
  • implantable systems
  • sensor and actuator materials
  • nanotechnology
  • biosensors and chemical sensors.

Facilities

We run several well-equipped optical and electronic test laboratories, including:

  • A full suite of industry-standard circuit design software
  • An electronics test and measurement laboratory
  • A materials laboratory suite
  • A microfabrication laboratory
  • A chemical sample preparation and electrochemistry laboratory.

We also have full access to the David Bullett Nanofabrication Facility, which is dedicated to nanotechnology research.
