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. Using this technology, the project plans to initially design and test a single optrode ....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. 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

The project aims to explore methods to significantly expand global internet data rates, by using emerging ultra-dense optical technologies. The project plans to discover how novel existing and emerging tiny photonic chip devices may enable the use of new, unused optical spectral bands, and then enable 1000s of channels to be supported by exploiting newly available parallelism in both wavelength and space. Success in the project aims may enable speeds of up to 100 times greater than achievable today, in a variety of fibre optic systems. Connectivity is key to our society, so benefits may arise in both future-proofing key Australian data infrastructure, and in providing a roadmap to support exponential capacity growth over the coming decades.Read moreRead less

This project aims to develop technologies for imaging through a multimode fibre that controls and measures each property of light; amplitude, phase, polarisation, wavelength and space as it propagates through an optical fibre. This will be pursued through the development of three prototype systems, where each system targets a particular property of light. The outcomes would ultimately enable multimode fibres to act as ultracompact, general-purpose optical conduits into the body through which a wide array of biomedical techniques can be performed in a minimally invasive fashion not currently possible.
