The Cochlear implant is an Australian invention (first prototype 1978), leading to the formation of Cochlear Ltd. to commercialise it. Cochlear Ltd. has now delivered implants to over 60,000 people in 70 nations across the world. Copycat companies have arisen overseas, but Cochlear Ltd. remains the market leader, due to their commitment to ongoing R&D. The present project involves magnetic resonance imaging and finite element analysis to study the current leakage pathways in the cranial cavity for the purpose of optimizing the design and placement of the return electrode. The obvious benefit of this is longer battery life. Better understanding of current leakage over other intracranial nerves is the other anticipated benefit.Read moreRead less
Novel antimicrobial surface coatings for Cochlear implants. The objective of this project is to develop new antimicrobial coatings for materials used to manufacture biomedical devices. 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.

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

This is significant to the community from prevention of pain, to the health care system that spends billions of dollars combating this modern day ailment and towards the industry where the low back pain is the single largest reason for sick leave in Australia. It will also give rise to employment of skilled technical people and an opportunity to increase high-value exports from Australia.Read moreRead less
Chip-scale implantable bionics for next generation therapeutic neural prostheses. Australia has an unmatched reputation as a world leader in neuroprostheses. Most notable of these is the bionic ear and, more recently, leading edge research towards a bionic eye. This project will combine the research strengths and experiences from both the hearing and visual bionics fields to address the main obstacles that prevent the number of electrical stimulation channels (equating to the number of frequenci ....Chip-scale implantable bionics for next generation therapeutic neural prostheses. Australia has an unmatched reputation as a world leader in neuroprostheses. Most notable of these is the bionic ear and, more recently, leading edge research towards a bionic eye. This project will combine the research strengths and experiences from both the hearing and visual bionics fields to address the main obstacles that prevent the number of electrical stimulation channels (equating to the number of frequencies heard by the deaf, and the number of spots of light seen by the blind) from increasing. The study will improve our understanding of the electrode-tissue interface, the life-long implantablity, and electrical circuitry that will allow future bionic devices to significantly improve their performance.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.

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
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.

Benefit can be had from collaborative research between these non-competing scientific fields. Microelectrodes is an area wherein overcoming the unique requirements of one field offers new opportunities in the other. We aim to enhance Australia's leadership in cochlear implants by applying decade-long research on electrode fabrication techniques for the bionic eye into 3D shapes for the cochlea. Furthermore, we aim to further improve the effectiveness, safety and reliability of the cochlear implant while facilitating increased electrode numbers.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
