Centre for Advanced Sensor Technologies
Tel: +44 (0) 1225 386330
The Centre for Advanced Sensor Technologies carries out research into highly accurate sensors and devices. These have a range of uses, including:
- New energy efficient lighting systems
- Cheap, fast and easy medical diagnostics, such as blood tests
- Monitoring of pollution
- Measuring cell damage in accident victims
- Making manufacturing more efficient
We are also interested in nanotechnology, microelectronics and optoelectronics.
What are we working on?
Our centre provides a focus for existing interdisciplinary research into advanced sensors and related technologies.
We are also involved in sensor-related research in several areas, including biomedical engineering, advanced semiconductors and the interface between the two.
One of our group's members, Professor Wang Wang, founded NanoGaN in 2008. The company produces Gallium Nitride wafers, a material that is important for a number of applications including blue-ray DVDs and advanced lasers.
CAST is a University research centre founded in 2006 with the principal aim of bringing together expertise in microelectronics, optoelectronics and novel materials.
Our research covers a wide range of areas such as electronic circuit and systems, wide bandgap semiconductors, LEDs, devices for medical applications, implantable systems, sensor and actuator materials, biosensors and chemical sensors.
