We are developing a miniature subdermal implant for biosensing. Once injected few millimetre under the skin, this implant will sense vital health parameters such as concentration of glucose, lactate, Na+, and K+ without painful procedure of drawing blood samples. The ultimate goal is to enable a routine process for continuous monitoring of these vital parameters in patients requiring critical care (e.g. ICUs or post-operation monitoring).

Through dense integration of silicon microelectronics and small photovoltaic cells optimized for near-IR spectrum (in collaboration with UNSW SPREE), the implant will only measure 1 x 3 mm in size. The device will harvest power and communicate using light with an external reader (e.g. using the camera and LED light on a smart phone) in a manner similar to reading a RFID tag.

Medical implant | Electronics | Biosensing

This is a team project involving several researchers, graduate students, research assistants and thesis students, spanning Biomedical Engineering, Electrical Engineering, and School of Photovoltaic & Renewable Energy Engineering (SPREE).

The ToR project will involve at least designing, build and testing printed circuit boards for CMOS integrated circuit testing, some FPGA digital synthesis, and potentially wet-bench testing of the devices. You should have a background in electrical engineering or mechatronics, and comfortable with working on circuit boards.
