Recently, the international journal "Science" published online the latest research result of the research team at Nankai University - all-weather self-sustaining human thermal management clothing driven solely by sunlight. A research team consisting of Professor Chen Yongsheng from the School of Chemistry at Nankai University, Professor Ma Rujun from the School of Materials Science and Engineering, and Professor Liu Yongsheng from the School of Chemistry has designed and prepared a flexible and sustainable personal temperature regulation system. This system can quickly respond to temperature changes in various extremely complex environments. Through flexible solar devices, the system can use the energy of sunlight to drive efficient electric card thermal management devices, expanding the thermal comfort zone of the human body from 22 ℃ -28 ℃ to 12.5 ℃ -37.6 ℃. It also has the characteristics of low energy consumption and high efficiency, requiring only 12 hours of solar energy input to achieve 24-hour controllable and dual-mode temperature regulation. A relatively constant body temperature is one of the important conditions for maintaining normal life activities in the human body. Clothing plays an important role in regulating human body temperature and maintaining thermal comfort. In areas with significant temperature differences between day and night or harsh living environments, how to safely, conveniently, and efficiently use clothing to keep body temperature within an appropriate temperature range is a worthwhile research topic. In recent years, researchers have developed various temperature regulation systems. However, due to the high energy consumption and low efficiency of these temperature regulation systems, they cannot operate for a long time without additional energy input. Moreover, its limited energy supply cannot support all-weather and self-sustaining thermal management regulation. "If it is possible to achieve cooling under the scorching sun, keep warm on cold nights, and utilize the ubiquitous solar energy to achieve the aforementioned all-weather and self-sustaining human thermal management, the living space of humanity will be greatly expanded," said Chen Yongsheng. Based on the progress made in flexible solar energy, electric cards, and thermal management in the early stage, the research team designed and prepared flexible solar cell modules and flexible electric card thermal management modules. Researchers have organically integrated the two and developed a new flexible and wearable active solar thermal management system, achieving bidirectional active human thermal management. By cooling the human body under sunlight (high temperature) and keeping warm in darkness (low temperature), the temperature range in which people can live has been increased by more than three times. At the same time, this new type of solar thermal management system can fully leverage the flexible characteristics of organic solar cells and electric card thermal management devices. Use it on clothing without affecting the wearing experience. In addition, the team has developed an efficient and proactive bidirectional human flexible thermal management system based on previous research accumulated in organic solar energy and electric cards. This management system has shown potential application prospects in the field of temperature regulation, but there are also some important scientific and technological issues that need to be solved, such as further improving energy efficiency, developing more efficient solar and card material devices, and optimizing integrated device structures. Chen Yongsheng said, "We will further optimize and improve the performance of our temperature regulation system, and make more contributions to improving the quality of human life in extremely harsh environments such as polar regions and space."
