A Multi-Optrode Array for Closed-Loop Bionics. We will design, implement and characterise a disruptive multi-channel optrode array (MOA) to record and stimulate excitable living tissue. The MOA will be a combination of individual optical electrodes (optrodes) that either comprise a new class of liquid crystals, used to passively sense extracellular biopotentials, or microphotovoltaic cells that will be used for electrical stimulation of excitable tissue.

We will design, implement and characterise a disruptive multi-channel optrode array (MOA) to record and stimulate excitable living tissue. The MOA will be a combination of individual optical electrodes (optrodes) that either comprise a new class of liquid crystals, used to passively sense extracellular biopotentials, or microphotovoltaic cells that will be used for electrical stimulation of excitable tissue. By employing light for communication with optrodes, this new approach alleviates many of the wiring, packaging and encapsulation issues associated with existing devices. Computational modelling and in vitro testing in cardiac tissue and retinal neurons will demonstrate the utility of the MOA to sense and control electrical activity.Read moreRead less
Design of an optrode for next generation brain-machine interfaces. The project plans to use a new class of liquid crystals – deformed helix ferroelectric (DHF) liquid crystal – to sense extracellular biopotentials. 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.

The project plans to use a new class of liquid crystals – deformed helix ferroelectric (DHF) liquid crystal – to sense extracellular biopotentials. 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. The final design would be a higher density sensor array using a fibre optic source and multiple optical couplers. This may support the development of new ways to implant sensing and diagnostic devices in the body.Read moreRead less

This project aims to determine the role of common glass constituents on desired optical properties. More than 50 major research groups and numerous commercial start-ups worldwide are pursuing ultrafast laser inscription, an enabling manufacturing platform used to create complex three-dimensional optical circuits inside transparent blocks of glass. However, although successfully used, we still don’t understand why similar glass types react differently, and we are limited to using generic glasses tailor-made for other purposes. This project will guide future choice of glasses and reveal how to engineer materials that complement this fabrication platform.Read moreRead less

This project will investigate the interaction between electromagnetic waves and mechanical motion in structured media. Enhancing this interaction will improve a number of modern technologies, such as nano-scaled motors, traps for biological samples and optical wrenches. Modern fabrication techniques will link the electromagnetic and mechanical properties of media, so that the electromagnetic forces will greatly increase, making such devices able to manipulate larger objects. Structured materials can also change their properties dynamically, enabling material properties to be altered in real time. This mechanism will form the basis of advanced tunable components to control waves at visible, infrared, terahertz and microwave wavelengths.Read moreRead less

This project will focus on a goal of engineering novel plasmonic metamaterials for manipulating light at the nanoscale. In particular, it will employ curved anodized alumina templates as well as 3D hybrid structures to explore light bending and strong resonances at the visible spectral range. Plasmonic metamaterials offer a unique ability to control subwavelength light propagation, for achieving unprecedented sensing sensitivities and emerging nanophotonics phenomena. However, fabrication challenges and high losses hamper their application in the visible spectral range. Engineering these plasmonic structures in a scalable manner should strengthen Australia’s economy, lead to new industrial companies in the emerging field of plasmonics, attract international investments and create job opportunities.Read moreRead less
