This interdisciplinary and intersectoral research project builds on the collaboration between the IETR laboratory of CNRS and the BodyCAP company. Our group at IETR interfaces fundamental, computational, and experimental approaches to elucidate the interaction of electromagnetic fields and biological media, to quantify it, and to develop novel biomedical applications. BodyCAP company develops miniaturized wireless physiological monitoring solutions for the healthcare, research, and high-performance sport.
Background and Mission
Emerging in-body biosensors offer powerful capabilities for medicine, clinical research, and basic science. Apart from direct application in ingestible and implantable biotelemetry (pH, T°, glucose sensors, wireless endoscopes, etc.), they are also useful for neural interfaces and electroceuticals. The sensing capabilities of in-body devices are severely limited by miniaturization and power-budget constraints. This postdoctoral project proposes to study the application of miniature antenna(s) of an in-body device for environment sensing via the near-field coupling with surrounding tissues.
The qualified candidate will further develop and contribute to testing of a wireless ingestible biotelemetry capsule with near-field sensing capabilities. He/she will focus on 1) studies of the near-field coupling with surrounding bio-tissues and optimization of in-body antennas for controlled sensitivity; 2) development, testing, and miniaturization of the associated RF measurement circuit; 3) contribution to the design, packaging, and testing of the final wireless system. To achieve these goals, the successful candidate will have access to unique interdisciplinary know-how of IETR in the field of complex radiating structures as well as to practical experience of BodyCAP in full-cycle development of wireless biotelemetry capsules. Last generation of high-performance workstations with GPU accelerators and advanced numerical solvers will be used to handle electromagnetic analysis and optimization. State-of-the-art manufacturing and measurement facilities will help with the prototyping and testing. The final wireless system will be characterized in tissue-equivalent models as well in vivo through established collaborations of IETR and BodyCAP. Finally, the successful candidate will be expected to present results of the work in high-profile journals and conferences.
