Abstract
This work addresses system aspects of implantable medical sensor devices. Different concepts for power supply and communication are compared and discussed. State of the art systems mainly rely on one common frequency for both wireless data and energy transmission. This publication highlights the specific pros and cons of different frequency ranges. The proposed Split Frequencies Concept (SFC) uses two separate frequency bands: One for energy harvesting and the second for data transmission. Hence the advantages of HF and UHF frequencies can be combined into a single system.
