A flexible thermal protective system is highly desirable for maintaining the safety of human body or spacecraft with complex profiles. However, it still challenging to attain high deformability and rapid cooling, especially intense chemical fire aerodynamic heat. Inspired by sweat gland skin, herein an adaptive two-layered skin developed based on inner hollow porous TPU/PVC fibers embedded in silicone water transportation outer PET spacer fabric storage transpiration. The were optimized good superhydrophilicity, porosity 79%, excellent (∼303%). (∼5 mm) shows biaxial (∼150%) attains a comfortable temperature (∼46 °C) under heat flux (420 kW/m2) within 1 s. Finite element simulation reveals that thickness 9 mm can reduce 1000 °C surface 20 0.7 We believe this paves effective way achieve cooling body, robotics, extreme environments.

Abstract The increasing heat flux in microelectronic device challenges traditional cooling methods. Thermoelectric coolers (TECs) offer effective hotspot management through direct integration with components. However, their efficiency is limited by thermoelectric properties, resulting high power consumption and additional thermal loads. This study introduces a 3D finite element model to optimize micro‐TEC variable cross‐sections. Key parameters, including cross‐sectional area ratio ( s ), packing density p d leg center width w height l external conditions (ambient temperature T m , load Q c ) are systematically analyzed. At = 90 °C 1 W, 120 legs cm − 2 0.5 mm identical TE volume, the novel design reduces from 1.97 W designs 1.56 reduction of 20.8%. Further optimization achieved minimum 1.43 at °C, 528 0.2 mm, 6.85. These findings provide framework for reducing TEC material costs, advancing efficient microelectronics.

Purpose The purpose of this paper is to determine the effect clothing fabrics, sizes and air ventilation rate on volume thickness gap under garments (AVGs). Design/methodology/approach geometric models human body were obtained by using a 3D scanner. Then distribution for four fabrics three rates (0L/S, 12L/S 20L/S) calculated Geomagic software. Finally, more suitable fabric was selected from analysis compare entrapped (S, M, L XL) rates. Findings results show that influence obvious than sizes. higher rate, thicker entrapped, evenly distributed gap. It can be seen in chest does not change significantly with changes rates, sizes, while waist affected significantly. Originality/value This research provides better understanding ventilated garments, which help designing optimal dimensions thus provide basis reference design AVGs.
