Article Abstract
Personal protective equipment pays attention exclusively to external safety protection and ignores the internal thermoregulation of physiological state in association with sweating. Herein, a super-hygroscopic calcium-doped poly(sodium 4-styrenesulfonate) and superhydrophobic metal-organic-framework-overlayed wearables (Ca-PSS/MOF) integrated cooling wearable is proposed for special personal thermal management (PTM). Compared to the pristine fabric, the superhydrophobic MOF wearables exhibit anti-fouling and antibacterial capabilities, and the antibacterial efficiency is up to 99.99% and 98.99% against E. coli and S. aureus, respectively. More importantly, Ca-PSS/MOF demonstrate significant heat index changes up to 25.5 °C by reducing relative humidity dramatically from 91.0% to 60.0% and temperature from 36.5 to 31.6 °C during the running test. The practical feasibility of the Ca-PSS/MOF cooling wearables is well proved with the protective suit of the fireman. Owing to these multifunctional merits, the sandwich-structured cooling Ca-PSS/MOF are expected to provide new insights for designing the next-generation multifunctional apparel for PTM.

Purpose: The environmental conditions in open water swimming (OWS) can impair thermoregulation. Here we explored and discussed four interrelated topics concerning the disruption of thermal homeostasis, in parallel with the underlying physiological mechanisms, during OWS competitions in hot climates: (i) potential health risks; (ii) possible impacts on performance; (iii) technical feasibility of core temperature (Tc) measurement; and (iv) cooling strategies applicable to this context.
Methods: An integrative review was conducted.

Ionic thermoelectric (i-TE) materials show promise for flexible energy harvesting and self-powered sensing due to their high ionic Seebeck coefficients (S). However, achieving both high thermoelectric performance and mechanical stretchability, especially in n-type systems, remains a critical challenge. Herein, a poly(vinyl alcohol) (PVA)-based n-type i-TE hydrogel is presented that exhibits both large negative S (-38.

Solar thermoelectric generators (STEGs) have recently gained increasing attention. However, their widespread adoption has been limited due to the lack of high-efficiency thermoelectric materials and compact heat sinks for effective heat dissipation. To address these issues, we develop a spectral engineering and thermal management strategy that significantly increases STEG power generation by 15 times with only a 25% increase in weight.

Phase change materials (PCMs) are highly renowned for their substantial latent heat capacity, enabling efficient thermal management in applications such as buildings, wearable devices, and lithium-ion batteries (LIBs). However, conventional PCMs suffer from mechanical rigidity, leakage, and low thermal conductivity. In this study, multifunctional, flexible, and leakage-proof phase change composites (PCCs) are developed to overcome these limitations and enable dual-mode thermal regulation for all-climate LIBs.
