Biomedical engineering

Innovating medical devices and capabilities for improved health

Our biomedical engineering research teams work across a range of application areas such as prosthetics, obstetrics, imaging and orthodontics to enable better health outcomes for our society.

Our industry partners: The Institute of Clinical Neurosciences at the Royal Prince Alfred Hospital

Liz Magdas (Macquarie University) developed a wireless device to measure patient walking trajectory during galvanic electrical stimulation of their vestibular apparatus, to provide a low-cost method of identifying vestibular problems. More robust communications hardware has improved the reliability of the link in congested hospital environments. Master of Philosophy student Amanda Stead has been developing hardware and software to examine some of the subtleties of gait during periods of vestibular stimulation.

Our industry partners: Gynaecology and Neonatology at the Royal Prince Alfred Hospital

Sarah McDonald has developed a second generation wireless device to monitor intrapartum activity. The device was designed to better understand uterine activity, the contraction profile and variations between individuals. The team continues to look at how they can improve the physical interfaces for the birth simulator to improve the midwives’ learning experience.

Weirong Ge has initiated a new project to instrument an Arabin cerclage pessary to allow the forces on the cervix to be monitored in real time.

Our partners: Professor Stuart Grieve and Dr Fraser Callaghan from Charles Perkins Centre

Our work on acoustic gating for triggering Magnetic Resonance Imaging (MRI) scans has improved the filtering process to separate cardiac sounds from those generated by the MRI before using a Bayesian classifier to identify differences between the S1 and S2 sounds. These are essential to ensuring correct triggering.

Work on low-cost prosthetic arms continues with University of Sydney student Aidan Kerr developing a new hand and forearm driven by twisted-string actuators with flex sensor angle feedback. Twisted string actuators provide high-linear force, which is ideal for tendon-based hand prosthetics.

We have led the development of a portable non-invasive hydration measurement device for athletes. It is operated by measuring bio impedance from wrist to wrist across the body. We examined micro-doppler signatures of long-distance runners in order to identify their fatigue levels.

A new project has been initiated to monitor the penetration of infrared radiation (NIR) from therapeutic light-emitting diode (LED) and laser sources through gum and jaw tissue into newly vacated tooth sockets. This research serves as a precursor to determining light efficacy in the healing process.
