The aim of this project is the theoretical study, design and characterization of implantable antennas dedicated to in-body telemetry. The latter is used to transmit sensor data from an implanted module to a base station located out of the body, and receive instructions (for drug delivery for instance) from the same base station. The applications we have in mind for this project are far field telemetry, where sensor communications with base stations relatively far from the body (up to 10-15 meters) are considered. This relatively large communication range is very valuable not only for patient’s quality of life, and also in the situation in vivo tests in animals, as it avoids the manipulation of animals and thus lowers their stress. Communication with body worn base stations will also be considered as a mean of performance comparison.
In the frame of this project, we plan to study the effect of a complex dielectric environment on the antenna characteristics (radiation efficiency, bandwidth, etc.) and elaborate new theoretical limits on what can be obtained, in other words the relation between the volume of the antenna, the characteristics of the tissue in which it is embedded, the radiation efficiency and the bandwidth. We will also study the suitability of well known antenna design and the relevant miniaturization techniques in the context of a lossy dielectric antenna environment and elaborate appropriate antenna optimization tool. A third objective of this project is to consider the adequacy of standard antenna measurement procedure for the in vitro testing of our antennas : it is indeed suspected that the lossy liquid surrounding the radiator will enhance the spurious cable effects well known in electrically small antenna characterization, and we will propose adequate measurement and or calibration setups to circumvent this effect. Finally, we will test the theoretical developments described above by designing ultra miniature implantable antennas that will be used in the i-IronIC project.
