Cardiovascular disease is the leading cause of death in Australia, killing one Australian nearly every 11 minutes. The World Health Organisation estimates that by 2030 almost 23.6 million people worldwide will die from cardiovascular disease, mainly from heart disease and stroke.

To assist in both the rapid diagnosis and long-term monitoring of heart attacks and stroke, our researchers are developing ambulatory solutions using impedance imaging, bio-impedance and bio-potential monitoring with a particular focus on the areas of neurology, cardiology and nutrition.

New instrumental methods that measure electromagnetic impedance are being trialled to enable rapid diagnosis at the scene. A portable Electronic Impedance Tomography Spectroscopy (EITS ) device – which measures tissue impedance to create an image of the tissue impedance distribution – could be used for monitoring stroke, epilepsy, and for detecting cancer. Recent advances in electromagnetic impedance-based methods are uniquely suitable due to their portability, safety, relatively low cost and fast acquisition speed.

Related bioelectronics hardware and algorithms will measure and classify biological signals, such as ECG, EMG, EEG, 3D position and location, skin conductivity, and blood oxygenation.

Impedance technologies are being investigated to track the body composition in newborn babies, firstly to identify those at immediate risk of malnutrition and secondly, to better understand the Barker hypothesis – the possible relationship between nutrition in utero and the development of cardiovascular disease in later life.
