Mr. Matthew Magill, Postgraduate Research Student
In recent years the use of implantable medical devices has increased as they allow improved monitoring and treatment of a wide range of medical conditions by providing real-time biotelemetric data. We’ve identified three main challenges with active RF implant communication systems:
We have devised a new, robust, implantable antenna that maintains its return loss and radiation performance in a broad range of tissue types, in a broad range of patients.
Our printed folded meandered dipole antenna (PFMD) has good radiative properties in all types of tissues, and is robust enough to withstand any environmental variations once implanted to allow link budgets to be pushed to their limit for maximum efficiency. This was verified through a range of measurements using accurate human tissue phantom test-beds that emulate the environments encountered in clinical applications. Our PFMD antenna will remove the current limitations of implantable medical devices and enhance future mobile health and medical wireless networks.
