A cantilever structure in 3D printed based on a fiber Bragg grating (FBG) sensor embedded in polymer material is proposed. The FBG sensor was embedded in 3D printed coating and was tested under three physical parameters: displacement, temperature and vibration. The sensor was tested in displacement in two different regions of the cantilever, namely, on its midpoint and end point. The maximum displacement...
A sensor based on Fabry-Perot interferometry with a hollow microsphere cavity embedded in a 3D printed structure is proposed. The sensor was tested for lateral loading and temperature, showing promising results. By imprintring the sensor on the structure, the dynamic range of application is severely increased enabling the application of the sensor in harsh environments.
Undernutrition has been associated with longer length of hospital stay (LOS). However, an analysis that investigates the association of recommended undernutrition diagnostic and screening indicators with LOS conducted in patients with a varied spectrum of pathologies and considering confounders would help to clarify their clinical value.We aimed to quantify the association of being undernourished...
