Resumen de: WO2025254973A1
A computational continuous glucose monitoring system is disclosed which integrates a biocompatible phosphorescence-based insertable sensor and a custom-designed phosphorescence imager (PI). This PI captures phosphorescence lifetime images of an insertable sensor through the skin where the lifetime of the emitted phosphorescence signal is modulated by the local concentration of glucose. The lifetime images acquired through the skin are processed by neural network-based models for misalignment-tolerant inference of glucose levels, accurately revealing normal, low (hypoglycemia) and high (hyperglycemia) concentration ranges. Using a 1-mm thick skin phantom mimicking the optical properties of human skin, in vitro testing of the PI using glucose-spiked samples yielded 88.8% inference accuracy, also showing resilience to random and unknown misalignments within a lateral distance of ~4.7 mm. Lateral misalignments beyond 5 mm prompted user intervention for re-alignment.
