Microbiological, chemical and sensory spoilage analysis of raw Atlantic cod (Gadus morhua): towards an integrated optical sensor for monitoring food quality Universiteit Gent
Near-infrared bulk optical properties of goat wound tissue and human serum: consequences for an implantable optical glucose sensor KU Leuven Universiteit Gent
Near-infrared (NIR) spectroscopy offers a promising technological platform for continuous glucose monitoring in the human body. Moreover, these measurements could be performed in vivo with an implantable single-chip based optical sensor. However, a thin tissue layer may grow in the optical path of the sensor. As most biological tissues are highly scattering, they only allow a small fraction of the collimated light to pass, significantly reducing ...
Fabrication and characterization of porous tissue-mimicking optical phantoms as a tool for optical sensor validation KU Leuven
This paper presents porous polydimethylsiloxane (PDMS) optical phantoms with tunable microstructural and optical properties to mimic porous biological tissues (e.g., fruit) during the design and optimization of novel optical setups. A well connected salt network formed using salt particles of various size distributions was used to obtain porous PDMS phantoms of different porous features including porosity, pore size distribution, pore number ...
Comparison of different polymers and printing technologies for realizing flexible optical waveguide Bragg grating strain sensor foils Universiteit Gent
Waveguides with Bragg gratings realized on a flat polymer foil are promising candidates for advanced strain sensors since such a planar approach allows precise positioning of multiple sensors in various well-defined directions, in the same foil. As such, an optical version of an electrical strain gage can be realized. Herein, several parameters are discussed which define the behaviour of such sensor foils, in particular the grating design, ...
Aerospace-grade surface mounted optical fibre strain sensor for structural health monitoring on composite structures evaluated against in-flight conditions Vrije Universiteit Brussel
Optical fibre sensors are being investigated since many years as candidates of choice for supporting structural health monitoring (SHM) in aerospace applications. Fibre Bragg grating (FBG) sensors, more specifically, can provide for accurate strain measurements and therefore return useful data about the mechanical strain state of the structure to which they are attached. This functionality can serve the detection of damage in an aircraft ...

FFR pressure wire comparative study for drift: piezo resistive versus optical sensor Universiteit Hasselt
Background: This study aimed to assess the stability of pressure derived fractional flow reserve (FFR) measurement and the handling performance of the OptoWire Deux with an optical pressure sensor relative to the PressureWire X with piezo resistive pressure sensors. Methods: This multicenter centre observational study included 50 patients between June 2017 and November 2018 undergoing a diagnostic coronary angiography with FFR measurement of ...
FFR pressure wire comparative study: piezoresistive versus optical sensor Universiteit Hasselt
Background This study aimed to assess the reliability of pressure derived fractional flow reserve (FFR) measurement and the handling performance of the OptoWire Deux with an optical pressure sensor relative to both the PressureWire X and the Verrata Pressure wire with piezoresistive pressure sensors. Methods This single centre study included 80 patients between October 2016 and May 2017 undergoing a diagnostic coronary angiography. The ...
