“…On the one hand, special PPE with ventilation and cooling can be customized for healthcare workers. Some studies [ 28 , [51] , [52] , [53] , [54] ] have tried to install fans on the PPE for cooling and ventilation to alleviate thermal discomfort. On the other hand, cooling vest with phase change materials (PCMs) or ice can be included underneath the PPE.…”

“…The results indicated that, during a surgical procedure, the surgeon's body was subjected to thermal load. Some studies have focused on the impact of protective clothing design and material composition on human thermal comfort [ [27] , [28] , [29] ]. For example, Troynikov et al [ 27 ] discussed the performance properties related to the thermal physiology and comfort of the wearer in relation to the function of protective clothing, along with comprehensive testing and analysis of the constituent materials and thermal manikin testing of experimental surgical clothing.…”

“…With the constant progress made by studies on contagious viruses, e.g., human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV), it is critical to maintain life safety and the health of the frontline workers via protection, control, correspondence, and investigation. Specifically, prevention is the most effective measure to block the spread of contagious viruses, and, therefore, advancement of suitable protective clothing becomes the priority [ 1 , 2 ]. Serving as an important barrier against the cross infection between patients and medical staff, medical protective clothing has been extensively studied.…”

Medical protective clothing is the first line of defense for medical staff, which makes the acquisition of protection and multiple function challenging. When it comes to contagious diseases, the physical properties of protective clothing are deemed the top priority and, subsequently, they have significant meaning for the structural design, production cost evaluation, convenient production, and innovation. In this study, nonwoven technology is employed to produce matrices in which mechanical properties are supported by Tencel fibers and recycled Kevlar fibers. Next, the electrostatic spinning is conducted to generate breathable and waterproof films. The nonwoven fabrics and membranes are combined to have diverse functions, forming lay-up compound matrices for medical protective clothing. Moreover, measurements are conducted to characterize the lay-up compound matrices in terms of the tensile strength, tearing strength, bursting strength, puncture resistance, stiffness, air-permeable property, surface resistance, comfort performance, sub-micron particulate filtration efficiency, and the penetration of synthetic blood. As for the nonwoven fabrics, the mechanical properties are significantly improved after Kevlar fibers are incorporated. The tensile strength is (62.6 ± 2.4) N along the machine direction (MD) and (50.1 ± 3.1) N along the cross machine direction (CD); the tearing strength is (29.5 ± 1.6) N along the MD and (43.0 ± 1.7) N along the CD; the bursting strength is (365.8 ± 5.0) kPa; and the puncture resistance is (22.6 ± 1.0) N. Moreover, the lay-up compound matrices exhibit a stiffness of (14.7 ± 0.2) cm along the MD and (14.6 ± 0.1) cm along the CD, a surface resistance of (2.85 × 109 ± 0.37 × 109) Ω, an air-permeable property of (45.4 ± 2.3) cm3/s/cm2, and sub-micron particulate filtration efficiency of over 98%. In the measurement for penetration of synthetic blood, the K40/PAN/TPU group prevents the synthetic blood from penetration. Hence, the incorporation of recycled Kevlar fibers and lay-up compound technique creates good physical properties, an appropriate comfort attribute, and functions, which suggests that this study provides a greater diversity and new concepts for the production of medical protective clothing.

The main challenge that the researchers have been facing these days is the thermohydraulic management of electrical and electronic devices since it plays a very crucial role in the efficiency of these devices. The same cause has been affecting the performance of automotive and space batteries. The temperature rise in the batteries has been affecting the life of the battery as well. For better performance and a long-life battery, the necessity of battery thermal management is important. In this paper, we are proposing a method to manage the high temperature with the help of Peltier cells attached to the battery. The cooling side of the Peltier cell will control the heat dissipated from the battery and the heating side of the Peltier cell will be optimized by the hydraulic pipes. As TECs (Thermoelectric Cooler) is a viable use in this technological growing world, we have been using them as our main thermal manager by using the cold side of the module. The Peltier cells are also been using in the formation of ice in the refrigerator and other applications where major low temperatures are required. With the effective usage of the Peltier cells, this paper proposes a method to manage the heat emitting from the battery.
