This paper presents a comprehensive experimental study on photoluminescent oxygen indicators and a rapid prototyping approach to manufacture biocompatible polymer films for future implantable sensors. Combining single photon avalanche diodes (SPADs) in a complementary metal-oxide-semiconductor (CMOS) technology, post-CMOS micro light-emitting diodes (μLEDs), and a photoluminescent layer allows for precise integrated oxygen detectors. To optimize the phosphorescent component, this paper provides extensive data by comparing different indicators, light sources, concentrations, and manufacturing technologies, tailored to the application in patient-specific implants.
