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
Ultra-low fouling active surfaces. 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.

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

Summary
New dimensions in organic bionics. The advent of the next generation of medical bionic devices is critically dependent on advances in multifunctional organic materials that, like living systems, provide spatial and temporal control. These advances will provide a platform to revolutionise medical treatments such as nerve and muscle regeneration, with impact on neural prosthetics.
Structural design of third generation biomaterials. This project will design third generation biomaterials for heart valves, cartilage and bones that guide the formation of new tissue whilst being dissolved inside the human body. As a result, it is anticipated that painful and costly revision surgery will become obsolete. Major benefits will be achieved in paediatric health as implants will have the ability to grow with the child.
Formation of bone-like materials for bone repair and regeneration. A successful outcome for this project would lead to the production and application of new bone-like calcium phosphate materials. Enhanced bioactivity of this material would lead to higher but controlled rates of calcium phosphate release. An understanding of the formation process of these materials and the controlled release of calcium phosphates has the potential to slow the development of metabolic diseases such as osteoporosis ....Formation of bone-like materials for bone repair and regeneration. A successful outcome for this project would lead to the production and application of new bone-like calcium phosphate materials. Enhanced bioactivity of this material would lead to higher but controlled rates of calcium phosphate release. An understanding of the formation process of these materials and the controlled release of calcium phosphates has the potential to slow the development of metabolic diseases such as osteoporosis. The WHO reports that osteoporosis is the second largest health care problem world-wide. In 2002, 44 million people in the USA were estimated to be at risk. This and similar figures in Australia and around the world emphasize the urgency of understanding and appropriately combating weak bone degenerative diseases.Read moreRead less
