This award supports the purchase of a thermal manikin custom-built for indoor and outdoor research studies in extreme heat conditions. This advanced instrument measures how much heat a human body receives and mimics the thermoregulatory system’s response in different situations. Use of this instrument will avoid the dangers of exposing humans to extreme heat while measuring how heat impacts human health and performance. Such measurements can help find better ways for individuals and organizations to cope with increasingly common and severely hot weather. More specifically, the benefits of this research may include fewer heat illnesses and deaths, improved societal well-being and productivity, improved urban planning, and reduced energy use required for air conditioning of buildings. To advance these topics, the manikin will be paired with a state-of-the-art mobile weather station developed at Arizona State University. These combined instruments will be used to simultaneously characterize the local environment and its impact on human thermal comfort, core and skin temperature response, and sweating. These processes will be measured in various settings (e.g., desert paths, old mobile homes, etc.) and allow testing of traditional and new cooling strategies. The research will be collaboratively performed by a diverse group of students and faculty from engineering, physical sciences, architecture, fashion, public health, nutrition, and sports sciences. The new thermal manikin will expose diverse and underrepresented student populations to new, interdisciplinary STEM research, thus promoting the participation in these fields. With recent instrumentation advancements and custom modifications requested of the manufacturer, the acquired thermal manikin system will be the first in the world to be easily moveable, compatible with high heat, and utilized to conduct multi-site outdoor and indoor measurements. Such experimentation will produce advanced information on the mimicked human thermoregulatory response presently unavailable from simulations, human trials, or current thermal manikins. The instrument will be used to 1) develop novel experimental methods and modeling approaches to quantify evaporative, conductive, convective, and radiative human heat exposure on 35 human body-zones and 2) to evaluate and improve indoor/outdoor thermal exposure and physiologic models and indices under oppressive heat across climate types and personal contexts. The manikin will also be used to accelerate development of a broad range of human-centric adaptations for coping with extreme heat.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项支持购买为极端高温条件下的室内和室外研究定制的暖体假人。这种先进的仪器可以测量人体接收到多少热量，并模拟体温调节系统在不同情况下的反应。使用该仪器将避免在测量热量如何影响人体健康和性能时将人体暴露在极端高温下的危险。这些测量可以帮助个人和组织找到更好的方法来科普日益常见的酷热天气。更具体地说，这项研究的好处可能包括减少中暑和死亡，改善社会福祉和生产力，改善城市规划，减少建筑物空调所需的能源使用。为了推进这些主题，人体模型将与亚利桑那州立大学开发的最先进的移动的气象站配对。这些组合仪器将用于同时表征当地环境及其对人体热舒适性、核心和皮肤温度响应以及出汗的影响。这些过程将在各种环境中进行测量（例如，沙漠小路、旧的移动的房屋等）并允许测试传统和新的冷却策略。该研究将由来自工程，物理科学，建筑，时尚，公共卫生，营养和体育科学的不同学生和教师团队合作进行。新的暖体假人将使多样化和代表性不足的学生群体接触到新的跨学科STEM研究，从而促进这些领域的参与。随着最近仪器的进步和制造商要求的定制修改，所获得的暖体假人系统将是世界上第一个易于移动，与高热兼容，并用于进行多地点室外和室内测量的系统。这样的实验将产生先进的信息模拟人体体温调节反应目前无法从模拟，人体试验，或目前的热假人。该仪器将用于1）开发新的实验方法和建模方法，以量化35个人体区域的蒸发，传导，对流和辐射人体热暴露，2）评估和改善室内/室外热暴露和生理模型以及在各种气候类型和个人环境下的压迫性热量下的指数。人体模型还将用于加速开发各种以人为中心的适应性措施，以应对极端高温。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
