Abstract

The human body must stay within a certain temperature range for comfort and safety. However, challenges for thermoregulatory clothing exist for harsh application scenarios, such as full day/night cycles, frigid polar regions, and space travel. We developed a flexible and sustainable personal thermoregulatory clothing system by integrating a flexible organic photovoltaic (OPV) module to directly acquire energy from sunlight and bidirectional electrocaloric (EC) devices. The flexible OPV-EC thermoregulatory clothing (OETC) can extend the human thermal comfort zone from 22°–28°C to 12.5°–37.6°C with a fast thermoregulation rate. The low energy consumption and high efficiency of the EC device allows for 24 hours of controllable and dual-mode thermoregulation with 12 hours of sunlight energy input. This self-powered wearable thermoregulatory platform has a simple structure, compact design, high efficiency, and strong self-adaptability with sunlight as the sole energy source.

仅利用阳光就能自我维持的个人全天候体温调节服

人体必须在一定的温度范围内才能保持舒适和安全。然而，在昼夜循环、极地严寒和太空旅行等严酷的应用场景中，体温调节服面临着挑战。我们开发了一种灵活且可持续的个人体温调节服系统，该系统集成了可直接从太阳光中获取能量的柔性有机光伏（OPV）模块和双向电致发光（EC）装置。柔性 OPV-EC 体温调节服（OETC）可将人体热舒适区从 22°-28°C扩展到 12.5°-37.6°C，并具有快速的体温调节速率。EC 设备能耗低、效率高，只需 12 小时的阳光能量输入，即可实现 24 小时的可控双模式体温调节。这种自供电的可穿戴体温调节平台结构简单、设计紧凑、效率高、自适应能力强，以太阳光为唯一能源。
