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. The growing field of bionics, where implantable electronic devices interface directly with the nervous system, is one such device. The expected ou ....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. 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
Numerical investigation of signal mechanotransduction of bone cells - application to bone remodeling. The understanding of signal mechanotransduction of bone cells is directly related to mechanical activation of bone remodeling processes, i.e., resorption and formation of bone tissue. Understanding of bone remodeling is essential for the development of new bone implants, the prognosis of osteosporosis, and studies related to changes in microgravity (e.g. space flight) to name a few key applicati ....Numerical investigation of signal mechanotransduction of bone cells - application to bone remodeling. The understanding of signal mechanotransduction of bone cells is directly related to mechanical activation of bone remodeling processes, i.e., resorption and formation of bone tissue. Understanding of bone remodeling is essential for the development of new bone implants, the prognosis of osteosporosis, and studies related to changes in microgravity (e.g. space flight) to name a few key applications. This research proposal closely aligns with one of the major national research priorities, i.e., promoting and maintaining good health (ageing well, ageing productively). The research project is aimed to understand how mechanically induced loading may activate remodeling of bone.

Fundamental theoretical and experimental investigation of cartilage mechanics. Arthritis and chronic joint symptoms are one of the leading causes of disability in the community, yet a fundamental understanding of joint mechanics has yet to be realised. The aim of this project is to develop a new state-of-the-art mathematical model describing cartilage behaviour in humans. The model will explain how activities like walking maintain healthy cartilage by transferring growth factors through the tiss ....Fundamental theoretical and experimental investigation of cartilage mechanics. Arthritis and chronic joint symptoms are one of the leading causes of disability in the community, yet a fundamental understanding of joint mechanics has yet to be realised. The aim of this project is to develop a new state-of-the-art mathematical model describing cartilage behaviour in humans. The model will explain how activities like walking maintain healthy cartilage by transferring growth factors through the tissue, and quantitatively explain how wear is minimised in cartilage through weeping lubrication. This model will progress our understanding of cartilage mechanics in health and disease, and so help Australians age well and productively.Read moreRead less

Summary
High-speed, three-dimensional, x-ray fluoroscopy for accurate measurement of human joint motion. This proposal addresses one of the most difficult and long-standing problems in the field of biomechanics: How can human joint motion be measured accurately and non-invasively during common activities such as walking, stair ambulation and running? Low-dose, high-speed, three-dimensional, x-ray fluoroscopy provides an excellent solution to this problem and, in so doing, can play a pivotal role in heal ....High-speed, three-dimensional, x-ray fluoroscopy for accurate measurement of human joint motion. This proposal addresses one of the most difficult and long-standing problems in the field of biomechanics: How can human joint motion be measured accurately and non-invasively during common activities such as walking, stair ambulation and running? Low-dose, high-speed, three-dimensional, x-ray fluoroscopy provides an excellent solution to this problem and, in so doing, can play a pivotal role in healthcare, through clinical gait analysis and gait rehabilitation (diagnosis, prevention and treatment of movement disorders); in sports, through the development of personalized training programs for elite athletes; and in entertainment, through the creation of physics-based animations for the video/digital games industry.Read moreRead less

Scaffolds for bone tissue regeneration and use in orthopaedic applications. Damaged joints do not repair spontaneously, often leading to arthritis. Bone defects resulting from congenital defects or disease processes are challenging to regenerate and represent a major financial burden to our health system. Bone graft treatments are widely used but have considerable drawbacks. This created a need for scaffolds to provide temporary support for new bone. However they lack the combined physical/biolo ....Scaffolds for bone tissue regeneration and use in orthopaedic applications. Damaged joints do not repair spontaneously, often leading to arthritis. Bone defects resulting from congenital defects or disease processes are challenging to regenerate and represent a major financial burden to our health system. Bone graft treatments are widely used but have considerable drawbacks. This created a need for scaffolds to provide temporary support for new bone. However they lack the combined physical/biological properties necessary for bone repair. We developed new scaffolds with improved mechanical/biological properties to mimic bone which will lead to new treatments for bone damage.Read moreRead less

Summary
Diamond cybernetics: nanocrystalline diamond for interfacing bionic devices with the human nervous system. Bionic devices will soon be used to treat disorders such as epilepsy, Parkinson's and depression. We will use diamond to create high resolution, permanent electrical connections between devices and the human nervous system. These diamond connections will preserve nerve health and make bionic devices more effective and able to last a lifetime.
