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

Multiscale Study on Biomechanical Roles of Soft Tissue on Bone Remodelling. The project aims to increase our knowledge of the processes of bone remodelling and the role of soft tissue in this process. Mechanical force is a key stimulus for regulating bone remodelling. A significant question in biomechanics is why orthodontics only use very small forces (1 Newton) to generate significant oral bone remodelling, whereas prosthodontics that apply three orders of magnitude higher forces (~1000 Newton ....Multiscale Study on Biomechanical Roles of Soft Tissue on Bone Remodelling. The project aims to increase our knowledge of the processes of bone remodelling and the role of soft tissue in this process. Mechanical force is a key stimulus for regulating bone remodelling. A significant question in biomechanics is why orthodontics only use very small forces (1 Newton) to generate significant oral bone remodelling, whereas prosthodontics that apply three orders of magnitude higher forces (~1000 Newton) do not move dental implants. This project aims to develop new multiscale modelling and remodelling techniques in computational mechanics to explore the roles played by connective soft tissue in bone adaptation. Expected project outcomes would increase our understanding in biomechanics and affect health care disciplines such as orthodontics, prosthodontics and orthopaedics.Read moreRead less
Real-time friction sensing, feedback and control for dexterous prosthetic and robotic manipulation. Prosthetic and robotic hands demonstrate poor dexterity during object manipulation, often dropping objects. Humans rarely allow objects to slip because we can sense when an object is slippery and adjust our grip. Exceptionally little research has been directed at replicating this ability to sense friction. This project aims to enable artificial hands to estimate frictional properties while graspin ....Real-time friction sensing, feedback and control for dexterous prosthetic and robotic manipulation. Prosthetic and robotic hands demonstrate poor dexterity during object manipulation, often dropping objects. Humans rarely allow objects to slip because we can sense when an object is slippery and adjust our grip. Exceptionally little research has been directed at replicating this ability to sense friction. This project aims to enable artificial hands to estimate frictional properties while grasping an object. Non-invasive methods to feed back this frictional information to an amputee will also be investigated. Finally, the friction-sensing system will be used to improve robotic gripper control. The outcomes of this research will significantly advance the fields of prosthetics, telesurgery, and service and manufacturing robotics.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
Nano-mechanical and nano-structural investigation of dentine: unravelling a novel nano-scale regulator of high durability of mineralised tissues. This project proposes that proteoglycans (PG) are key regulators of the high durability of dentine. PGs are primarily responsible for the structural organization of collagen in all vertebrates, however virtually nothing is known about their role on the biomechanics of mineralized tissues. This study aims to thoroughly address this question.
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
