Novel RF Controlled Electromechanical Microvalve. The significance of the proposed microvalve is its potential use in exciting biomedical applications such as in drug delivery and fertility control. For human body implantation, it must be batteryless, wireless and be made of a biofriendly-polymer. We propose to meet all three criteria, based on novel use of surface acoustic waves (SAWs) as the actuation mechanism in a polymer material.

We propose to meet all three criteria, based on novel use of surface acoustic waves (SAWs) as the actuation mechanism in a polymer material. Energy for actuation will be supplied by a radio frequency (RF) signal. We propose to model, design and demonstrate the device in laboratory conditions. This will enable development of application specific designs in future programs, such as ARC linkage.Read moreRead less

Summary
Feedback control as a tool for enhanced neuroprosthetic stimulation. The aim is to use control theory tools to find optimal stimulation parameters to use in a bionic implant. This project will lead to improvements in understanding of mechanisms underlying electrical stimulation and to improvements in medical bionics technologies.
Model-based estimation methods for improved classification of electroencephalographic data: application to monitoring depth of anaesthesia. This project will use advanced computing methods applied to electrical brain wave recordings to track how the brain changes as a person undergoes general anaesthesia during surgery. This will lead to better anaesthesia monitoring devices and reduce the chances of people experiencing pain during surgery or IQ deficits after the anaesthesia.

Nervous tissue stimulation using Multi-Junction Silicon Photodiodes. Currently, in order to stimulate different areas in nervous tissue, brain-machine-interfaces (BMIs) usually rely on multi electrode arrays where each electrode is connected to a wire, that connects to other electronics, all of which has to be safely encapsulated, thus increasing the size of the devices and complicating the surgical procedure for implanted devices. This project aims to develop a silicon multi-junction photodiode ....Nervous tissue stimulation using Multi-Junction Silicon Photodiodes. Currently, in order to stimulate different areas in nervous tissue, brain-machine-interfaces (BMIs) usually rely on multi electrode arrays where each electrode is connected to a wire, that connects to other electronics, all of which has to be safely encapsulated, thus increasing the size of the devices and complicating the surgical procedure for implanted devices. This project aims to develop a silicon multi-junction photodiode that can provide a photovoltage high enough to efficiently excite nervous tissue. A BMI based on this approach could be much smaller and could be powered optically via thin fibres, thus in the long run enabling smaller and safer implants for restoring function in disabled people.Read moreRead less
Individually addressable, active, multipoint electrodes for bio-potential recording and electrical impedance imaging. We will develop non-invasive devices based on biosignal and impedance monitoring. They will be highly portable and based on comfortable electrode patches that can be applied quickly in emergencies. The technology may be used to save lives and reduce disabilities by monitoring strokes and heart attacks and stimulate Australia's biomedical industry.
Engineering the Next Generation of Terahertz Laser Imaging Systems. This project aims to develop terahertz imaging systems based on quantum cascade lasers suitable for characterisation of skin, with major implications for early skin cancer detection. Despite advances in treatment regimes, the most significant predictor of skin cancer survivability remains early detection. The project’s approach uses the semiconductor laser in the optical-feedback interferometer configuration, and is designed to ....Engineering the Next Generation of Terahertz Laser Imaging Systems. This project aims to develop terahertz imaging systems based on quantum cascade lasers suitable for characterisation of skin, with major implications for early skin cancer detection. Despite advances in treatment regimes, the most significant predictor of skin cancer survivability remains early detection. The project’s approach uses the semiconductor laser in the optical-feedback interferometer configuration, and is designed to afford significant advantages over conventional terahertz imaging platforms. The project plans to explore new semiconductor physics of a quantum cascade laser under optical feedback, engineer the semiconductor laser-based platform for medical diagnostic applications, and develop supporting numerical techniques.Read moreRead less
