Attempt is made in this paper to propose the use of galvanic skin response method to determine the level of emotion (stress), in case of normal activities. Special attention was put to develop measurement, which can minimize limiting of movements of a person, by implementing wearable sensor.
In this paper, we demonstrate enhancing of the paper-based packaging by printing structures with inkjet printer. The most popular substrate within the logistic or grocery market is paper. Such printer can manufacture electroconductive or dielectric areas on paper type substrate. Due to low cost and high recyclability it is the most desired substrate for making improvements. We report on a significant increase of the quality of mentioned printouts by using Peltier Cell. Such structures can be printed on surface of the package or on special layer of the hydrophilic paper. Such porous paper can be implemented into box and be combined into sensing areas.
In this paper, we demonstrate a combination of foil and InkJet printed structures in Lab-on-Paper device. Such a device can be used to analyze a concentration of salt in water (or any other substance) by measuring the impedance of the analyte. Lab-on-Paper can perform an analysis on a microscopic volume of substances. Their advantages is low price, small size or can be easy disposable or stored. In the paper was presented manufacturing and testing of device with colorimetric pH testers and impedance measurement.
In this paper, we demonstrate an automatic image analysis for Micro Total Analysis Systems (μTAS) or Lab-on-Paper (LoP). By placing fiducial markers on μTAS, application can crop image and remove bending distortions, also it can perform colorimetric analysis. With previously taken photo of μTAS device with applied reagents, user can determine ie. illness presence by uploading photo into the program. In the paper was prepared μTAS sheet, algorithm for finding fiducial points and software for colorimetric analysis written in Matlab.
In this paper, we demonstrate a manufacture of the Lab-on-Foil device used to analyze a composition or concentration of fluid by measuring an electrical capacitance of flowing analyte. Lab-on-Foil devices allow to perform a full-fledged action on a very small volume of the substance. Their popularity is due to the low production cost, small size and short production time. In the paper it will be presented technology of the manufacturing, testing and implementation of components in the complete device.
In this paper, we demonstrate a manufacture of the tapered optical fiber used to analyze the composition or quality of fluid by measuring the external refractive index of the desired analyte. They were made in two ways: using a laser plotter and professional station to do such a tapered fibers. The results prove that utilization of the tapered fiber is really useful to microfluidic domain.
In this article we present the preliminary studies for the flood embankment monitoring system based on the fibre Bragg gratings. The idea of the system is presented. The Bragg resonance shift is transformed to the change of the power detected by the standard InGaAs photodiode. The discrimination of the received power was executed by another fibre Bragg grating with different parameters. The project of the fully functional system is presented as well.
