Fiber Bragg Grating-Based Smart Garment for Monitoring Human Body Temperature

"Body temperature gives an insight into a person's physiological condition and body temperature changes," says a human health scientist. At a 0. 5 Hz vibration rate, FBG sensors had good vibration resistance, and the wavelength changed about 0-u20131 pm. Hot melt glue was applied to the garment and the optical fiber by the electric iron and the hot press machine, joining the FBG sensor, the optical fiber, and the garment. The sensor can reach the human armpit temperature in about 10 minsu201315 min with the upper arm close to the torso, according to experiments on human body temperature.

The Application of Biomechanics Combined with Human Body Structure in Volleyball Technical Analysis

"With the growth of volleyball, the growth of traditional school volleyball has been gaining importance. " The aim of this paper is to apply biomechanics' experience to investigate serving technology and attacking volleyball's technologies. This paper discusses the human body's finite element modeling approach in the area of biomechanics. The upper limbs of volleyball players are designed and tested, and four good teams have been selected for video analysis of volleyball offensive skills.

Contactless Electrocatheter Tracing within Human Body via Magnetic Sensing: A Feasibility Study

"Real-time estimation of a metal lead within the patient's body is obtained by radiographic imaging during surgical procedures. " Although fluoroscopy uses reduced radiation intensity, the overall X-ray dose administered during prolonged exposure times poses dangers to patient and physicians' wellbeing. In principle, it is possible to trace the lead's location by making a weak current flow through the lead and monitoring the associated magnetic field generated outside the body. The lead's small coil with a ferrite core was carried along a grid of points over a plastic sheet and placed just above the lead to measure the spatial amplitude distribution of the magnetic field produced by the lead. The main coil axis of the plane was oriented along the x and y axes of the plane for each measurement point to determine the magnetic induction field's associated parts.

Diagnostic biomarker kinetics: how brain-derived biomarkers distribute through the human body, and how this affects their diagnostic significance: the case of S100B

"Abstract Blood biomarkers of neurological disease are often used to rule out or confirm the presence of significant intracranial or cerebrovascular pathology or for the differential diagnosis of conditions with similar characteristics. " Our incomplete knowledge of the kinetic properties, release patterns, and excretion of molecules derived from the brain has hampered more widespread use of biomarkers related to brain health. S100B partition into peripheral organs, and cell permeability of S100B in astrocytes are among the key variables that influence biomarker levels in blood or saliva: blood or saliva: blood or saliva, blood-u2013brain barrier permeability, the S100B partition into peripheral organs, and the cellular levels of S100B. After an episode of BBB disruption, this open-source model can also mimic other indicators, such as GFAP or NF-L's kinetic behavior.

Computer-Aided Depth Video Stream Masking Framework for Human Body Segmentation in Depth Sensor Images

"For such a challenge, three-dimensional depth images or image sequences can be used, which represent the object's location information in a 3D scene retrieved from depth sensors. " This paper gives a framework for designing foregroundu2013background masks from depth images for human body segmentation. The framework can be used to accelerate the manual depth image annotation process with no semantics known beforehand, and it can use segmentation using a sophisticated algorithm, but the user only controls the parameters, or corrects the automatic segmentation results, or gives it suggestions by drawing a boundary of the desired object.

A Uniform Magnetic Field Generator Combined with a Thin-Film Magneto-Impedance Sensor Capable of Human Body Scans

"The system consists of both a uniform magnetic field generating unit capable of the inserting of a whole human body as well as a high-sensitivity magnetic sensor array embedded in the strong magnetic field. " The aim of the system, which was developed in this study, is to nondestructively detect a cluster of magnetic nanoparticles in a human body and to measure the location and concentration of the clustered magnetic particles. A prototype system involving a magnetic field generator with a radius of W500 mm u00d7 L200 mm and a single magnetic field of 370 Gauss is described in this paper. The sensor chip, which was also installed in the system, found the detection of 2 mm ellipsoidal magnetic chips at a distance of 27 mm from the sensor element, according to the company.

Modeling di (2-ethylhexyl) Phthalate (DEHP) and Its Metabolism in a Body’s Organs and Tissues through Different Intake Pathways into Human Body

"To explore the mechanisms behind the accumulation of PAEs in different tissues or organs such as the liver and lungs as a result of indoor PAE exposure in different phases, including oral digestion, dermal adsorption, and inhalation, a whole-body physiologically based pharmacokinetic model for PAEs is used to characterize the dynamic process of phthalates by various intake routes, including oral digestion, cutaneous adsorption, and inhalation. " The gastrointestinal blood, urine, the liver, the thymus, the pancreas, the pancreas, the spleen, the heart, and kidney were simulated for various intake scenarios based on the estimated parameters. The simulation findings revealed a diverse accumulation profile of DEHP and MEHP in organs and tissues, revealing that the different intake routes would result in different accumulation profiles of DEHP and MEHP in organs and tissues, which may lead to different health outcomes.

Ionic Gelatin-Based Flexible Thermoelectric Generator with Scalability for Human Body Heat Harvesting

thermoelectric conversion has the characteristics of quietness and continuity among WEH's most popular choices due to its freedom of light condition or the wearer's movement. " TEG has therefore become a good option for harvesting low-grade heat energy such as human body heat. Optical thermoelectric gel has the benefits of a large Seebeck coefficient, clearly defined shape and size, low processing cost, wide material sources, and simple encapsulation, etc. Through a series of characterization experiments, the optimal compound quantity of SiO 2 NPs is found, and the optimization process is explored. The LTEG converted energy in a capacitor and directly drove a calculator without a DC-u2013DC booster, since storing the converted energy in a capacitor.
