Electro-triggered solidification of supercooled fusible alloys. Stiffness is typically considered a static property of a material. Traditionally, once the stiffness is specified, it is not expected to change during operation. This project aims to turn a problem (i.e., supercooling) into an opportunity for creating fusible alloy composites with electroprogrammable stiffness that can outperform state-of-the-art materials by offering all desirable properties. Expected outcomes are the rapid, contin ....Electro-triggered solidification of supercooled fusible alloys. Stiffness is typically considered a static property of a material. Traditionally, once the stiffness is specified, it is not expected to change during operation. This project aims to turn a problem (i.e., supercooling) into an opportunity for creating fusible alloy composites with electroprogrammable stiffness that can outperform state-of-the-art materials by offering all desirable properties. Expected outcomes are the rapid, continuous, large, and reversible change in stiffness of the composite through electrical control. This project will provide significant benefits by enabling an increasing number of emerging applications in areas such as robotics, manufacturing, and consumer wearables that require materials with tuneable stiffness.Read moreRead less
Integrated Piezoelectric Microsystems for Actuation and Sensing. Piezoelectric transducers provide the highest positioning accuracy of any known actuator and the highest dynamic force resolution of any known sensor. However, these capabilities are limited to macro scale applications since piezoelectric materials are not compatible with integrated circuit (IC) or Micro-Electro-Mechanical Systems fabrication processes. This project aims to extend the use of piezoelectric materials to the meso- and ....Integrated Piezoelectric Microsystems for Actuation and Sensing. Piezoelectric transducers provide the highest positioning accuracy of any known actuator and the highest dynamic force resolution of any known sensor. However, these capabilities are limited to macro scale applications since piezoelectric materials are not compatible with integrated circuit (IC) or Micro-Electro-Mechanical Systems fabrication processes. This project aims to extend the use of piezoelectric materials to the meso- and micro-scale by fabricating miniature piezoelectric positioning and sensor systems. These devices will include six-axis nano-positioners and ultra-high resolution accelerometers and gyroscopes. This technology will create a new market for devices that are lower cost than macro-scale systems but provide higher performance than silicon based microsystems.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

The electrical power industry in Australia is undergoing a massive revolution to an intelligent, low-carbon and sustainable smart grid environment. However, due to the heavy reliance on cyber infrastructure and the intermittence of renewables, smart grid will inevitably introduce new security issues, for example, cyber security. This project is to investigate emerging security issues together in a comprehensive framework where quantitative models and analysis methods will be explored for smart grid cascading failure analyses. Then innovative three-stage reinforcement strategies (three lines of defence) will be developed to enhance the resilience of smart grid against natural disasters and intentional attacks, and potential large blackouts.

This project aims to develop the theory and tools to address the control of complex interconnected systems. There is currently an enormous disconnect in decentralised control between the celebrated theoretical advances and the concepts that are used for implementation, or even for computation. The project expects to isolate the key reasons for this disconnect and develop ways to address the control of complex interconnected systems. The expected outcome is a tool which can observe information from only a small portion of a network but which may ultimately effect a large portion of the network. This includes smart building management, multi-vehicle systems and convoys, irrigation networks, large array telescopes, and the power distribution grid.Read moreRead less
