This paper introduces an implantable pulse oximeter to measure continuously SpO2 in patients suffering from a chronic respiration disease. We cover the design and the prototyping of the main building blocks, namely the wireless power and data link and the photosensor front-end circuits. The implant measure and transmits the SpO2 data to a host computer for analysis and storage. A rechargeable battery charged through a resonant link is utilized to supply the implant. The implant has a diameter of less than 3 cm.
