AI Technical Summary
Technical Problem
Existing stretchable interconnects struggle to combine high stretchability and high conductivity, and their complex and costly manufacturing processes limit their application under high strain conditions.
Method used
A water-soluble PVA fiber is wound around a hydrophobic polymer core. A stretchable spiral cavity structure is created by dissolving the fiber, and a conductive medium is filled using vacuum negative pressure to form a continuous conductive interconnect.
Benefits of technology
It enables the efficient and low-cost manufacture of interconnects that combine high stretchability and high conductivity, making them suitable for mass production.

Abstract
本发明公开了一种可拉伸互连线的制造方法。该制造方法具体为：首先，使用倒模法制造出憎水性的高分子聚合物(如PDMS，Ecoflex等)内芯；接着，使用水溶性的PVA纤维对聚合物内芯按照一个方向，对内芯从一端到另一端进行缠绕，形成多圈匝线；然后，将PVA纤维缠绕的聚合物内芯放置于另一个大尺寸的模具中，使用同样的高分子聚合物进行灌注；等聚合物固化后，将整体浸润到水中，将水溶性PVA纤维溶解，留下连续的匝线空洞；最后，利用负压将液态金属、碳纳米管分散液等导电介质压入空洞中，形成连续导电的互连线。本发明结合实际情况，可以调节拉伸范围，具有很强的泛用性。该方法高效、成本低、简单、制备方法满足大规模生产的需求。
