Abstract: The device for detecting and/or determining the concentration of an analyte present in a tissue includes a sensor which is an optical fibre interferometer, and one interferometer arm being coated with an immobilised binding agent enabling selective binding of the analyte. The interferometer arm is mounted inside a guide enabling puncturing the tissue and performing an in situ measurement without the necessity to collect or prepare a sample. The guide is provided with a closed guide face, longitudinal perforations on sidewalls enabling the analyte to reach the binding agent, and an opening in the input end of the guide for introducing the interferometer with the arm into the guide. At the input end, the opening is sealed, enabling the isolation of the interior of the guide from the surroundings. The interferometer is mounted in a position in which the interferometer does not touch the inside walls of the guide.

Abstract: Machine-learned networks provide generative design. Rather than emulate the typical human design process, an inverse model is machine trained to generate a design from requirements. A simulation model is machine trained to recover performance relative to the requirements for generated designs. These two machine-trained models are used in an optimization that creates further designs from the inverse model output design and tests those designs with the simulation model. The use of machine-trained models in this loop for exploring many different designs decreases the time to explore, so may result in a more optimal design or better starting designs for the design engineer.
