The present invention relates to a personal health monitoring system including an implantable sensor and a monitoring device. The present invention further relates to a multiple user health monitoring system including a plurality of such personal health monitoring systems. The present invention further relates to a method of monitoring the biological parameters of at least one user.

Personal health monitoring system, multiple user health monitoring system, and method

A sensing system comprises a photonics integrated circuit partially encapsulated by an encapsulation material and the photonics integrated circuit comprising a first integrated sensor accessible to a target analyte and being positioned in a part of the photonics integrated circuit not being encapsulated by an encapsulation material, and a second integrated sensor accessible to a reference substance and being positioned in a part of the photonics integrated circuit that is encapsulated by an encapsulation material. The sensing system is further adapted to, when in use, comprise the reference substance but less or no target analyte between the second integrated sensor and the encapsulation material as compared to the amount of target analyte being present at the first integrated sensor.

Photonic embedded reference sensor

An implantable optical sensor () comprising a substrate () and at least one optical microstructure () for evanescent field sensing integrated with the substrate (), the at least one optical microstructure () being positioned to form an optical interaction area () on a part of a surface () of the substrate (), the optical assembly () further comprising a thin protective layer () covering at least the optical interaction area (), the thin protective layer () being in a predetermined material with corrosion-protection characteristics and having a predetermined thickness, so as not to affect the evanescent field sensing.

Implantable optical sensor

An implantable optical sensor comprises a photonic integrated circuit comprising a substrateand an optical microstructureintegrated with the substrate. The optical microstructure is positioned to form an exposed optical interaction areaon a part of a surfaceof the substrate. A cover capis sealed onto a part of the substrateadjacent to the optical interaction areaand by wafer-to-wafer bonding technology or another wafer-level hermetic packaging technique. At least one active componentis positioned in a sealed cavitywhich is formed between the surfaceand the cover cap. The substratecomprises at least one optical feedthrough, which is an embedded waveguide extending from the sealed cavityto the optical interaction area
