北卡罗来纳州立大学的工程研究人员创造了一种超薄,可拉伸的,可透气的电子材料。 透气性可使材料呼吸,使其穿着更舒适。研究人员设计了专门用于生物医学或可穿戴技术的材料,在这种技术中,透气性使汗液和挥发性有机化合物从皮肤上蒸发掉。

透气功能使可穿戴电子设备在长期佩戴时更加舒适。研究人员说,相对于早期的可拉伸电子产品,透气性是一个很大的进步。这些团队说,他们开发的材料很重要,因为这是一个易于扩展的简单过程。研究人员使用了一种称为呼吸图法的技术来制造具有均匀孔分布的可拉伸聚合物薄膜。

通过将薄膜浸入含有银纳米线的溶液中进行涂层,然后对材料进行热压,将纳米线封住。研究人员表示,这种薄膜在导电性、光学透光性和水蒸气渗透性方面表现出了良好的组合。由于银纳米线正好嵌入到聚合物表面以下,该材料在汗水的存在下也具有稳定性。

团队创建的材料很脆弱,只有几微米厚。穿戴式电子设备的透气性对舒适性非常重要,因为如果不透气,则会引起皮肤刺激。团队创建的第一个原型是可安装在皮肤上的干电极,用作电生理传感器。这种传感器具有多种潜在应用,包括ECG和EMG测量。
