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
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.
High-fidelity, long lasting, single-neuron brain machine interfaces. The ability to conduct stable, high resolution recording and stimulation within the brain is critically important to the development of technologies that interface electronics with the human body. Devices that interface directly with the brain are increasingly important in brain research, medical monitoring, treatment of neurological diseases or the enormous increase in brain-machine interface technologies. Carbon Cybernetics h ....High-fidelity, long lasting, single-neuron brain machine interfaces. The ability to conduct stable, high resolution recording and stimulation within the brain is critically important to the development of technologies that interface electronics with the human body. Devices that interface directly with the brain are increasingly important in brain research, medical monitoring, treatment of neurological diseases or the enormous increase in brain-machine interface technologies. Carbon Cybernetics have developed a high-density neural recording and stimulation array that employs fine carbon fibres as the electrode material. We aim to show that this array can record from the brain indefinitely, without loosing signal quality, and the same array can be used to stimulate the brain to recreate memories or sensations.Read moreRead less
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. This project aims to investigate the role of protein adsorption in electrode performance, including impedance and material dissolution. To enable these in ....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. 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
Conformal Bionics - addressing the challenges in bringing miniaturised implants to the site of therapeutic delivery. Smaller, more sophisticated, lifetime-implantable bionic devices capable of being placed at the site of therapeutic delivery will facilitate new or improved opportunities for treatment of disease. Three critical areas of research aim to be explored in pursuit of this goal will be addressed within this study: introduction of new fabrication materials that enable devices to conform ....Conformal Bionics - addressing the challenges in bringing miniaturised implants to the site of therapeutic delivery. Smaller, more sophisticated, lifetime-implantable bionic devices capable of being placed at the site of therapeutic delivery will facilitate new or improved opportunities for treatment of disease. Three critical areas of research aim to be explored in pursuit of this goal will be addressed within this study: introduction of new fabrication materials that enable devices to conform to the anatomy of the targeted site of therapeutic delivery; improved means of addressing the data and energy transfer needs of devices implanted in confined spaces; and innovation of novel sensors for testing and monitoring of atmospheric conditions within the implant to anticipate and safely manage issues relating to a breach of hermetic encapsulation barriers.Read moreRead less
Biomimetic blood bag materials for prolonged platelet storage. Platelet storage is limited to five to seven days before there is a reduction in viable platelets. This results in a continual mismatch between supply and demand resulting in patients in remotes areas or those that have rare phenotypes missing out on platelets. It also results in the wastage of platelets because they expire before they can be used clinically. This project aims to extend the platelet shelf life beyond seven days by de ....Biomimetic blood bag materials for prolonged platelet storage. Platelet storage is limited to five to seven days before there is a reduction in viable platelets. This results in a continual mismatch between supply and demand resulting in patients in remotes areas or those that have rare phenotypes missing out on platelets. It also results in the wastage of platelets because they expire before they can be used clinically. This project aims to extend the platelet shelf life beyond seven days by developing biomimetic blood bag materials that reflect the natural molecular structures of blood vessels through the use of novel synthetic and biological materials. With the realisation of longer platelet storage times, this project aims to have significant impacts on the health and economic benefits of Australians.Read moreRead less

Infection associated with the use of biomaterials such as biomedical implants, catheters and orthopaedic prostheses is a major barrier to the use of these devices. The coatings that the project plans to develop are based on novel antimicrobials which have been shown to prevent adhesion and colonisation of biomaterials by bacteria in vivo. This strategy has the potential to prevent device-related infections and revolutionise the biomaterials industry.Read moreRead less
