Research outputs pre 2011
Pacemakers are common biomedical devices used in the treatment of specific cardiovascular problems. Current research in biomedical engineering is investigating the use of so called brain pacemakers to regulate conditions such as Parkinson's and other neurological conditions. In this paper, we demonstrate the principle of acoustic communications and power harvesting, in vivo. The signals are intended to be used for fixed in vivo biomedical devices, such as pacemakers, were wired and wireless RF communications cannot be used. Results show the performance of the communications channel. The frequency response, transfer function and transient response (at resonance) of the communications channel were …

Theses : Honours
A photonic power system using a silicon or germanium based device as a photonic power converter was proposed. The properties of each device were investigated to determine the optimum structure, design, configuration and efficiency for power conversion. These included, but were not limited to, device geometry, doping concentration and the wavelength of the incident beam. Relevant inferences were made from the results obtained and compared to previous work. Currently, research into photovoltaic power converters is focused on the efficiencies of complex heterostuctures made from gallium-arsenide compounds. Here, the properties of a silicon device were investigated in detail as the predicted …
