Summary
Synchrotron-based modelling of the deformation and fracture mechanism in normal and osteoporotic femurs under multiaxial loading cycles. The femur is a light-weight structure designed to best perform in life. However, the complex tissue architecture, microstructural organisation and its complex loading regimens make it difficult to understand how the femur can deform and fracture. This project studies femoral fractures by modelling the proximal femur with a micrometric level of detail. Synchrotr ....Synchrotron-based modelling of the deformation and fracture mechanism in normal and osteoporotic femurs under multiaxial loading cycles. The femur is a light-weight structure designed to best perform in life. However, the complex tissue architecture, microstructural organisation and its complex loading regimens make it difficult to understand how the femur can deform and fracture. This project studies femoral fractures by modelling the proximal femur with a micrometric level of detail. Synchrotron femur images are taken in loaded and unloaded conditions. Cortical strain and fracture are measured, replicating possible multiaxial loads. Micro finite-element models will be used to study the contribution that the bone tissue architecture, tissue structure and activity types make to the fracture. The resulting knowledge will have future orthopaedic applications.Read moreRead less

Broad spectrum nanomedicine for Meningitis treatment. Brain inflammatory diseases are among the top ten infectious causes of death. The project aims to provide Australian doctors with a superior alternative of treating infections that do not respond to conventional antibiotics. The nanomedicine developed will reduce the burden of hospital and boost Australia economy in the biomedical sector.
Advanced micro-architecture and nanotopography for enhanced tissue growth in scaffolds. Tissue engineering scaffolds offer an urgently needed synthetic biomaterials solution to overcome disease transmission from donor transplants. This work will combine biomaterial chemistry and designed surface topography to trigger bone formation within a scaffold for the first time in the world. Collaboration with national research leaders on stem cell and animal testing of the new scaffolds will provide the ....Advanced micro-architecture and nanotopography for enhanced tissue growth in scaffolds. Tissue engineering scaffolds offer an urgently needed synthetic biomaterials solution to overcome disease transmission from donor transplants. This work will combine biomaterial chemistry and designed surface topography to trigger bone formation within a scaffold for the first time in the world. Collaboration with national research leaders on stem cell and animal testing of the new scaffolds will provide the necessary interdisciplinary approach to generate a new product for patients in need of bone regeneration. Australia will benefit from the contribution to medical science, the development of a new device for rapid prototyping tissue engineering scaffolds, retain biomaterials research expertise, and generate new biomedical products.Read moreRead less
Functional Electronic Stimulation of Muscles - Development of a Model for Sensory Feedback to Amputees and Vision for the Blind. Electrical stimulation of nerve fibres is an emerging physiological technique with great promise towards rehabilitation.

Electrical stimulation of nerve fibres is an emerging physiological technique with great promise towards rehabilitation. The field lacks techniques for detailed, focal application of stimuli to recruit specific fibres for fine muscle control or conveying useful neurosensory information. The investigator has developed microtechnology for delivering stimuli to 100 sites, conceivably facilitating recruitment of specific fibres within a given bundle. Effects of muscle stimulation are readily measured and shall be used to model and refine techniques for generic high-resolution fibre recruitment. Benefits include, improved muscle control in functional electrical stimulation, sensory perception for amputees and patterned vision from optic nerve stimulation.Read moreRead less

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
Large-scale Parallelization of Neural Stimulation in a Visual Prosthesis. Over time, engineers have been able to treat a large number of disorders through new technologies. For example, the deaf can now hear again through cochlear implants. Similar efforts to provide vision to the blind, however, have met with difficulties owing to the high quantities of sites that must be stimulated to provide 'useful' vision. This study addresses the important issues relating to the delivery of large quantitie ....Large-scale Parallelization of Neural Stimulation in a Visual Prosthesis. Over time, engineers have been able to treat a large number of disorders through new technologies. For example, the deaf can now hear again through cochlear implants. Similar efforts to provide vision to the blind, however, have met with difficulties owing to the high quantities of sites that must be stimulated to provide 'useful' vision. This study addresses the important issues relating to the delivery of large quantities of electrical stimulations to surviving nerves in the eyes of blind patients in an effort to devise a beneficial visual prosthesis or 'bionic eye'. The outcomes of this study could substantially enhance Australia's already prominent reputation in neurostimulation and provide much needed treatments to vision disorders.Read moreRead less

This project aims to develop chemistries and fabrication approaches through innovative materials evaluation to develop ultra-low fouling active electrode surfaces. Development of ultra-low fouling surfaces will have significant impact in a range of applications where system or device failure is attributed to fouling. The growing field of bionics, where implantable electronic devices interface directly with the nervous system, is one such device. The expected outcomes will be an understanding of the material requirements that lead to the elimination of protein and cell accumulation at surfaces that degrades the performance and lifetime of these implants. The findings will benefit any application where fouling is a problem.Read moreRead less
