“…The fact of the matter is that there are many difficulties in measuring the temperature of the wire due to its small diameter and the condition surrounding the wire. Therefore, the heat transfer analysis [37] of the wire was carried out using the heat transfer equation for convection with a mass coefficient and Brinson's model to describe the thermomechanical behavior of the SMAs, as the convection determines the equation of the heat transfer model and the average value of heating and cooling [37]. It is worth noting that the main parameters in this equation are applicable in engineering calculations and can also be easily determined by typical engineering experiments.…”

<span lang="EN-US">People with broken bones suffer from symptoms of muscular atrophy as a result of a lack of movement, so it was necessary to find effective solutions due to the relative pain they cause and the difficulty of movement after healing. In this paper, we proposed a smart splint made of nickel-titanium shape memory alloys (SMA) wires. These alloys have unique properties compared to other materials, the most important of which is maintaining the original shape during manufacturing at a certain temperature. Temperature, pressure, as well as humidity, were analyzed and monitored while the patient wore the splint to reach the best possible results by using a microcontroller. The results showed that there was a significant improvement for the muscles in a short time when using the proposed splint, as the percentage of qualified muscle recovery increased by more than 70% when using the usual splint. The wires used had an effective role in rehabilitating these muscles by performing a permanent local massage. due to the different diameters of these wires, a different response to temperature change was recorded.</span>

“…Non-invasive methods can now measure blood sugar, body temperature, and heart rate [26]. This patient-friendly approach to glucose monitoring meets the urgent need for better disease management, improved treatment adherence, and ultimately, a higher quality of life for diabetics [27]. While non-invasive glucose monitoring has some margin of error, validation through comparative analysis with invasive methods is crucial [28], [29].…”

Optical sensors offer a painless method of monitoring blood glucose levels using various light technologies to analyze blood characteristics without penetrating the skin. The literature review part reflects the progress in optical sensor technology evaluates its potential in blood glucose monitoring by overcoming the limitations of conventional methods and recognizes the challenges and future prospects in this rapidly developing area of research. The results of empirical studies are then presented. The methodology is presented as a non-invasive method of blood glucose monitoring based on near-infrared spectroscopy. To precisely evaluate blood glucose concentrations, spectroscopy techniques involving absorption and reflection are employed at wavelengths 450, 900, 1350, and 1800 nm. After absorption and reflection of glucose molecules, light is generated. An experimental study of different samples revealed a linear relationship between the final output voltage and sugar concentration. The results demonstrate a correlation between blood glucose level and signal intensity after transmission.

“…The particle-to-fluid ratio is lower and therefore the particle-particle force is neglected [20]. Since in this simulation blood is assumed to be fluid and particle and the highest percentage of blood is plasma (approximately 54% of human blood volume as a whole) [21], the properties of plasma are assumed to be the properties of the base fluid.…”

Bloodstream infections have a high mortality rate with >80,000 deaths per year in North America. The inability to detect pathogens quickly in the early stages of the infection causes high mortality. Such inability has led to a growing interest in developing a rapid, sensitive, and specific method for identifying these pathogens. The rapid detection of bloodstream infections requires the rapid and efficient separation of bacteria from the blood. But the problem is that the number of bacteria is much lower than other blood components. The blood culture step needs to be accomplished first for bacteria identification and antibiotic susceptibility testing. As the blood culture is time‐consuming, a method based on the insulator‐based has been presented that increases the number of bacteria by combining the blood culture method and increasing the concentration. In this model, the dielectrophoresis technique was utilized in a curved microchannel with a constriction for sorting three particle sizes including 9, 7–4 μm, as well as smaller than 3 μm. The results showed that the applied voltage and the channel dimensions affect separation efficiency. Suppose these values are properly selected (for example, a voltage of 110 V that was causing the maximum electric field of 200 V/cm). The proposed model can completely (100%) separate larger than 9 μm and smaller than 3 μm particles. The proposed model has simple geometry and is considered an appropriate technique for sorting all bacteria separation in bloodstream infection.
