Proposed Project Title: Wearable Biosensing Using mm-Scale Medical Implants

Principal Supervisor: Professor William Scanlon           Second Supervisor: Dr Gareth Conway

Project Description:

Micro miniature wireless sensing has great potential for application in many domains including medical diagnostics and treatment. Current implanted (under the skin) sensing systems are simply too power hungry and too large to be practicable in medical applications, yet there are many clinical requirements for in-situ (in-body) monitoring of parameters such as pH or oxygen tension. The aim of this project is to investigate the miniaturisation of wireless biosensors such that they can be small enough to inject into the human body, directly avoiding invasive surgery. This will bring many challenges, particularly given the mm-scale size constraints and complicated bioelectromagnetic environment of the human body.

The QUB Centre for Wireless Innovation has an excellent pedigree in this area with two decades of research into wearable communications and medical implants. The group has state-of-the-art facilities including internationally unique human body phantoms and wearable device measurement systems. The project would suit graduates of a wide range of disciplines including electronics, physics and biomedical engineering, although prior study of electromagnetics is essential. The project can be tailored to suit the skills, experience and aspirations of the candidate and there will be opportunities for genuine co-operation with clinical researchers including members of the Centre for Cancer Research & Cell Biology at Queens.

The main objectives of the project are to:

  • Use of novel bioelectromagnetic modelling techniques to investigate the design, performance and optimisation of microminiature sensors.
  • Development of appropriate radiowave propagation (channel) models and antenna systems for implanted biosensors
  • Application to novel clinical applications such as intra tumoural biosensing or GI-tract co-operative robots through co-operation with clinical partners.
