Abstract

The application of thermoelectric devices (TEDs) for personalized thermoregulation is attractive for saving energy while balancing the quality of life. TEDs that directly attach to human skin remarkably minimized the energy wasted for cooling the entire environment. However, facing the extreme dynamic geometry change and strain of human skin, conventional TEDs cannot align with the contour of our bodies for the best thermoregulation effect. Hence, we designed a kirigami-based wearable TED with excellent water vapor permeability, flexibility, and conformability. Numerical analysis and experimental results reveal that our product can withstand various types of large mechanical deformation without circuit rupture. The stated outcome and proposed facile approach not only reinforce the development of wearable TEDs but also offer an innovative opportunity for different electronics that require high conformability.

通过叽里格米实现用于体温调节的柔软贴合人体的电子器件

应用热电设备（TED）进行个性化体温调节，对节约能源和平衡生活质量具有吸引力。直接附着在人体皮肤上的 TED 可显著减少用于冷却整个环境的能源浪费。然而，面对人体皮肤极端动态的几何形状变化和应变，传统的 TED 无法与人体轮廓保持一致，从而达到最佳的体温调节效果。因此，我们设计了一种基于叽里格米的可穿戴 TED，它具有出色的水蒸气渗透性、柔韧性和顺应性。数值分析和实验结果表明，我们的产品可以承受各种类型的巨大机械变形，而不会发生电路断裂。所取得的成果和提出的简便方法不仅加强了可穿戴 TED 的发展，还为需要高保形性的不同电子产品提供了创新机会。
