未来的电子产品预计将发展成可穿戴形式，并且考虑到人体中发生的各种运动，对于即将到来的可穿戴电子产品需要足够的拉伸性。沿着可拉伸性，透明性可以增加未来可穿戴电子产品的功能性和美学特征。在这项研究中，我们证明，第一次，一个高度可拉伸和透明的电磁干扰屏蔽层的可穿戴电子应用与银纳米线渗透网络的弹性聚（二甲基硅氧烷）基板。所提出的可拉伸且透明的电磁干扰屏蔽层即使在高拉伸应变条件下也显示出高的电磁波屏蔽效率。基于银纳米线逾渗网络的电磁干扰屏蔽层有望超越传统的电磁干扰屏蔽材料，将其应用范围扩展到生物系统、人体皮肤、可穿戴电子等需要光学透明或非平面表面环境的各种领域。
Future electronics are expected to develop into wearable forms, and an adequate stretchability is required for the forthcoming wearable electronics considering various motions occurring in human body. Along with stretchability, transparency can increase both the functionality and esthetic features in future wearable electronics. In this study, we demonstrate, for the first time, a highly stretchable and transparent electromagnetic interference shielding layer for wearable electronic applications with silver nanowire percolation network on elastic poly(dimethylsiloxane) substrate. The proposed stretchable and transparent electromagnetic interference shielding layer shows a high electromagnetic wave shielding effectiveness even under a high tensile strain condition. It is expected for the silver nanowire percolation network-based electromagnetic interference shielding layer to be beyond the conventional electromagnetic interference shielding materials and to broaden its application range to various fields that require optical transparency or nonplanar surface environment, such as biological system, human skin, and wearable electronics.
