IEEE APS CHAPTER LECTURE - Prof. Leena Ukkonen - Backscattering-based wireless communication and power transfer to small biomedical implants

Share

In this presentation, we will focus on different aspects of backscattering-based wireless communication and power transfer to small biomedical implants. We will present different antenna topologies for data and power transfer through tissue, in vitro and in vivo studies on implantable intracranial pressure (ICP) sensors and give insight and analysis on wireless link reliability in tissue environment. We will also present radio frequency identification (RFID) -based implant platform and communication method. Moreover, we will focus on differences and challenges of in vivo environment compared to laboratory phantoms and tissue models. In our studies, different types of implantable antennas have been tested to investigate reliability, accuracy and sensitivity of the brain implants: a hybrid near field-far field system with a piezoresistive sensor for ICP monitoring, a UHF band spilt-ring resonator system and LC tank based miniature implantable antenna. This presentation will explain these implant antennas and wireless power transfer in tissue environment present in human head.
