During mechanical ventilation, the humidification of dry air delivered by ventilator is recommended. Among several solutions, heated wire humidifiers (HWHs) have gained large acceptance to be used in this field. The aim work fabricate a measuring system based on fiber Bragg grating (FBG) for simultaneous monitoring gas relative humidity (RH) and temperature, intended providing feedback HWHs' control. This solution can implemented using an array two FBGs having different center wavelength....
There is a growing demand of comfortable and unobtrusive wearable systems for monitoring variety physiological parameters in particular the respiratory frequency ( f <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">R</sub> ). The most popular techniques cannot be used several clinical applications unstructured environment. These issues have fostered dramatic growth interest devoted to monitor . In this arena, fiber Bragg grating (FBG) sensors...
Plants are primary resources for oxygen and foods whose production is fundamental our life. However, diseases pests may interfere with plant growth cause a significant reduction of both the quality quantity agriculture products. Increasing agricultural productivity crucial poverty food security improvements. For this reason, 2030 Agenda Sustainable Development gives central role to by promoting strong technological innovation advancing sustainable practices at level. To accomplish aim,...
The importance of humidity control is spreading through a broad spectrum applications, from food and pharmaceutical industries to biomedical chemical fields. During the last decades, growing interest in fiber Bragg gratings (FBG) led new approaches applications for measurement by means deposition hygroscopic materials on gratings. influence coating material its features such us thickness (tk) concentration (wt%) static dynamic metrological properties have been investigated this paper. In...
Stereoregular polymerization of (p-nitrophenyl)acetylene (pNPA) was performed using [Rh(norbornadiene)Cl]2 and [Rh(cyclooctadiene)Cl]2 catalysts to give poly((p-nitrophenyl)acetylene) (PpNPA), with a cis−transoid form under mild conditions. The polymer underwent isomerization from the predominant cis trans when compressed at 200 kg/cm2 room temperature. polymers, obtained before after compression, were characterized IR, CP MAS 13C NMR, ESR, diffuse reflective UV methods. data suggest that...
Fiber Bragg grating (FBG) sensors have gained popularity in medicine for some valuable features, such as small size, immunity to electromagnetic interferences, and good metrological properties. Among several applications, this technology has been used the analysis of gases mechanical ventilation. In field, particular during invasive ventilation, gas delivered by ventilator must be warmed humidified order reach patients with optimal conditions (100% relative humidity 37 °C). The most popular...
In this work, we report novel relative humidity sensors realized by functionalising fibre Bragg gratings with chitosan, a moisture-sensitive biopolymer never used before for kind of optic sensor. The swelling capacity chitosan is fundamental to the sensing mechanism. Different samples were fabricated, testing influence coating design and deposition procedure on sensor performance. sensitivity was measured in an airtight humidity-controlled chamber using saturated chemical salt solutions....
