Connecting man to machine: Wireless brain-machine interface. This project aims to enable direct wireless transmission of brain signals leading to reliable thought control of computers, wheelchairs, exoskeletons and vehicles. Such technology is currently limited by the fidelity, reliability, safety and longevity of the electrodes used to record signals from the brain. Partner organisation, SmartStent, has developed a novel stent-based electrode array which allows the extraction of high fidelity n ....Connecting man to machine: Wireless brain-machine interface. This project aims to enable direct wireless transmission of brain signals leading to reliable thought control of computers, wheelchairs, exoskeletons and vehicles. Such technology is currently limited by the fidelity, reliability, safety and longevity of the electrodes used to record signals from the brain. Partner organisation, SmartStent, has developed a novel stent-based electrode array which allows the extraction of high fidelity neural information without risky brain surgery and implant rejection. The project aims to combine SmartStent's stent-electrode technology with the diamond materials technology developed by the research team for hermetic encapsulation of electronics.Read moreRead less
Surface Engineered Biomaterials to Control Inflammation. The overarching aim of this project is to provide a mechanistic understanding of how surface nanotopography affects inflammatory responses. Experimental evidence demonstrates that engineered surface nanotopography in combination with surface chemistry downregulates the expression of proinflammatory cytokines from primary macrophages. The significance of these findings is that it may be possible to engineer the nanotopography of a biomedica ....Surface Engineered Biomaterials to Control Inflammation. The overarching aim of this project is to provide a mechanistic understanding of how surface nanotopography affects inflammatory responses. Experimental evidence demonstrates that engineered surface nanotopography in combination with surface chemistry downregulates the expression of proinflammatory cytokines from primary macrophages. The significance of these findings is that it may be possible to engineer the nanotopography of a biomedical device surface in a manner which leads to a desired and predictable level of inflammation and subsequent foreign body reaction (FBR) medical implants and tissue engineering constructs.Read moreRead less

Novel antimicrobial surface coatings for biomedical applications. There are currently no effective biomaterial coatings to reduce device related infections. Such materials are needed to address the high rates of infection that can occur. The melimine technology proposed here has the potential to significantly reduce rates of infection, reduce health care costs and advantage the Australian biomaterials industry.
Smart Matrix™ approaches towards neo vascularisation in bone repair. Bone injuries cost Australia more than $1 billion annually. The development of a medical device combining novel pro-angiogenic technology, Smart Matrix™, with polymer scaffolds for treatment of bone defects by this project, will facilitate rapid development of a blood supply within the defect, aiding bone growth and reducing overall costs compared to current treatments.
Nanoengineered gradient substrata as a novel approach for understanding infection mechanisms. This project will advance our understanding of how bacteria colonise surfaces and will also inform the development of novel antibacterial coatings and diagnostic tools for device-associated infections, which have a significant impact on patients and are a huge burden to the healthcare system.
Biological determinants of the safety and stability of neuroprosthetic stimulation electrodes. Performance of cochlear implants and the quality of sound perceived by patients is strongly related to electrode impedance. Electrode impedance fluctuates relative to the implant electrical activity, but the mechanisms which cause this are not clear.

Performance of cochlear implants and the quality of sound perceived by patients is strongly related to electrode impedance. Electrode impedance fluctuates relative to the implant electrical activity, but the mechanisms which cause this are not clear. This project aims to investigate the role of protein adsorption in electrode performance, including impedance and material dissolution. To enable these investigations a new biomimetic analogue of the perilymph (cochlea fluid) is intended to be developed. Additionally, the project aims to investigate two strategies to minimise impedance changes: small pulse electrode cleaning and antifouling coatings. Understanding and control of factors influencing electrode stability aim to facilitate next-generation implant designs.Read moreRead less
