Research at WiMed

Macquarie University WiMed Research Centre hosts a multi-disciplinary team of researchers from Engineering, Medicine and Science working together to develop future wireless implant medical devices and their applications.

With the ever-growing interest for more sophisticated medical devices and biological sensing of various kinds, the WiMed Research Centre was formed to provide practical solutions in wireless technology as applied to these problems. The WiMed Research Centre is a highly collaborative research environment, anchored by Macquarie University’s Department of Engineering rich history and cutting-edge contributions in wireless electronics and communications but highly collaborative across the University’s emerging strengths. Majority of the activities leverage the growing body of work at the Faculty of Medicine and Health Sciences.

Implant Radio Platforms, Program Leader: Prof. Karu Esselle

This research program aims to develop a series of flexible wireless implant platforms that can be optimised for specific neurological and cardiovascular applications. Current research includes shorter-term activities (1-2 years) to develop implant platforms operating at 400MHz and 900 MHz aimed at animal and human telemetry; and a longer-term activity (5 years) to develop an implant platform operating at higher ultra-wideband frequencies aimed at a wider range of implant applications.

Cardiovascular Devices, Program Leader: Prof. Itsu Sen

Our cardiovascular research focuses on the study of the characterisation of cardiovascular haemodynamics and optimal design of medical devices for cardiovascular/cerebrovascular disease treatment and diagnosis. Wireless technology is potentially being available for application in new generation medical devices, including implantable cardiovascular-assistance and endovascular treatment devices.

Biocompatible Materials & Sensors, Program Leader: Prof. Candace Lang

This research program’s focus is on developing and fabricating materials and micro-devices. Projects involve nanoparticles for chemical and optical detection of molecules, materials and fabrication methods as well as electrical, mechanical and optical detection methods for particles, molecules and physiological states such as rare cells, blood glucose, and blood pressure.

Neurological Devices, Program Leaders: Dr David Inglis and Prof Ann Goodchild

This research program aims to develop implant technologies tailored for neurological applications. The current focus is on developing an implantable microelectrode drug delivery array for management of neurological disorders.

Medical Imaging Technologies, Program Leaders: Prof. Yves De Deene

Our Medical imaging research is focussed towards the quantitative mapping of physiological parameters such as cellular densities, cell size distributions, acidity (pH), oxygen and metabolite concentrations. This multi-disciplinary research involves the development of new software and hardware. In order to boost the sensitivity of MRI with several orders of magnitude, our research group is also developing hyperpolarized MRI techniques which opens up new horizons of molecular, metabolic and cellular imaging. We also organize workshops on magnetic resonance imaging (MRI) physics and technology.

Radiotherapy Technologies, Program Leaders: Prof. Yves De Deene

Our research in radiotherapy technology is focussed towards the development of radiation dosimeters that provide the radiation dose distribution in three dimensions. These 3D dosimeters can be cast in an anthropomorphic shape and have proven to be very useful in safeguarding the entire radiotherapy chain of cancer patients, especially with the introduction of imaged gated treatment modalities. This research is highly multi-disciplinary and involves chemistry, optics, radiation physics, mechatronics, mechanics and medical imaging.

Orthopaedics Devices, Program Leaders: A/Prof. Desmond Bokor and A/Prof.Richard Appleyard

Our research is looking to develop micro sensors for use internally to monitor and evaluate the stresses developed in joint replacements as patients go about their daily activities with the aim to detect early failure. Other sensors we are interested in include temperature and motion. Other research projects include developing surface monitoring devices to 4-dimensionally track patient arm motion, compliance with rehabilitation programmes, development of a surgical robotic system for ENT surgery and electrical stimulation. Electrical stimulation is used to treat many debilitating diseases and conditions including spinal cord stimulation for pain relief and deep brain stimulation. We are interested in improving the clinical performance of these devices which are currently limited in the number of stimulating electrodes. By using ‘current steering’ methods, we hope to improve current electrode positions and configurations, hence minimising cross-talk.
