    Abstract: Dialysis patients may be affected by renal failure and may be affected by other health conditions, such as hypertension. During and between dialysis sessions, it may be advantageous to monitor various characteristics of the patient and of the dialysis system. As such, a system and method for dialysis biomarker monitoring is provided.

    Abstract: A photonic integrated device comprising: a photonic integrated chip (PIC) adapted to investigate blood flow at a portion of tissue of a user, said PIC comprising: a laser having an optical output, or waveguide for guiding an optical output from an external laser, the optical output being split into a first optical component and a second optical component; wherein the first optical component is arranged to be transmitted to and generate speckle at the portion of tissue of the user; the photonic integrated device further comprising: one or more detectors, each detector configured to receive the speckle generated by the first optical component at the portion of tissue; and one or more optical splitters optically coupling the second optical component to one or more respective input(s) of the one or more detectors; wherein the photonic integrated device is further adapted to measure interference at the one or more detectors between a sample arm formed by the first optical component and a reference arm formed by the second optical component.

    Abstract: An optical sensor for spectroscopic analysis of a sample, the optical sensor comprising: a photonic integrated chip (PIC) for providing light to the sample, the PIC comprising: one or more laser(s) designed to operate at one or more respective predetermined wavelength(s), each of the one or more laser(s) having an output that is optically coupled to an optical output of the PIC; and a monitor located on the PIC for determining the wavelength of the optical output; the optical sensor further comprising: a detector for collecting a spectrum from the sample; and one or more processors configured to: compare the wavelength of the laser(s) at the optical output with each of their respective predetermined wavelength(s); and if a deviation above a certain threshold is detected between the wavelength of the laser(s) and the predetermined wavelength(s), adapt the collected spectrum to generate a reconstructed spectrum; and use one or more datapoints from the reconstructed spectrum for the spectroscopic analysis.
