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.

香港城市大学于欣格团队 | 通过剪纸技术实现用于温度调节的柔性共形电子

本研究论文聚焦通过剪纸技术实现用于温度调节的柔性共形电子。在节约能源与保证生活质量的同时, 将热电设备 (TEDs) 应用于个性化的体温调节具有非常大的吸引力。直接贴附在皮肤上的热电设备能够显著降低因冷却整个环境而产生的能量浪费。然而, 面对人体皮肤呈现的极端动态的几何形状和应变, 传统的热电设备无法贴合人体轮廓以达到最佳的体温调节效果。因此, 本文基于剪纸技术设计了一种具有出色的透气性、柔性和共形性的可穿戴式热电设备。数值分析和实验结果均表明, 本文开发的热电设备能够承受各种类型的大程度的机械变形, 且不会导致电路断裂。上述成果和所提出的简便方法不仅推动了可穿戴式热电设备的发展, 还为各种需要高度共形性的电子设备提供了创新机遇。
