Special Issue Information

Dear Colleagues,

Polymeric systems for personal thermal and moisture management have drawn increasing attention in the past decade due to their great potential for various applications, including wearable thermoregulation, building energy-saving, stimuli-responsive cooling and warming, and tunable liquid moisture management. Personal thermal and moisture management is the controlled transport of heat, vapor, and liquid from the skin surface to the environment through the fabric clothing and microclimate region. It is of considerable importance for optimizing comfort and maximizing the performance of human beings in different environments and climates. Advances in wearable technology and smart materials have enhanced portability and reduced the weight of the polymer-based thermal and moisture management systems. Moreover, the regulation of thermal (i.e., cooling and warming) and moisture conditions of buildings consume large energy, e.g., approximately 15% of all energy used in the United States. The development of personal thermal and moisture management systems enables the expansion of air-conditioning setpoints of buildings, resulting in significant energy saving.

This Special Issue will deliver new insights, achievements, and reports on recent progress in the field of polymeric systems for personal thermal and moisture management, including materials, devices, systems, models, and simulations. It not only provides solutions for existing problems but also new ideas for future generations. In particular, this Special Issue invites original full articles, communications, and reviews in the following areas:
• Wearable thermoregulation devices
• Responsive textiles and clothing for personal cooling and warming
• Next-generation wearable thermal and moisture sensors
• Smart functional materials for thermal and moisture management
• Biomimetics for thermal and moisture management
• Energy generators for thermal and moisture management
• Controllable heat and liquid transport
• Modeling and simulation of personal thermal and moisture transport

Skin wetness and body water loss are important indexes to reflect the heat strain of the human body. According to ISO 7933 2004, the skin wetness and sweat rate are calculated by the evaporative heat flow and the maximum evaporative heat flow in the skin surface, etc. This work proposes the soft textile-based sensor, which was knitted by stainless steel/polyester blended yarn on the flat knitting machine. It investigated the relationship between electrical resistance in the weft/warp directions and different water absorption ratio (0–70%), different sample size (2 cm × 2 cm, 2 cm × 4 cm, 2 cm × 6 cm and 2 cm × 8 cm). The hydrophilic treatment effectively improved the water absorption ratio increasing from 40% to 70%. The weft and warp direction exhibited different electrical behaviors when under dry and wet conditions. It suggested the weft direction of knitted fabrics was recommended for detecting the electrical resistance due to its stable sensitivity and linearity performance. It could be used as a flexible sensor integrated into a garment for measuring the skin wetness and sweat rate in the future instead of traditional measurements. Full article
