This project aims to establish a new approach to enable a reliable and accurate prediction of precision surface grinding. Precision grinding is often the final step in the manufacturing chains for a broad range of metal, ceramic, optical glass and semiconductor components, which must have ultra-high surface integrity and accurate dimensions. To date, the surface integrity of a ground component cannot be predicted due to the involvement of many random factors and variables in a precision surface grinding process, resulting in high failure rates and processes requiring repeated surface measurements. The novel approach for surface integrity prediction developed by this project will make a vital step forward in advancing the discipline of precision surfacing, establish a new knowledge base and bring about significant technological impacts to the manufacturing industry.Read moreRead less

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

In response to an applied electrical field, it has been shown that DHF crystals can modulate a polarised light source with extraordinary sensitivity and linear response down to the microvolt range. Using this technology, the project plans to initially design and test a single optrode device on the bench, before in vitro testing and characterisation using two-photon microscopy.
