Abstract: A stretchable circuit board has stretchability as well as flexibility of the flexible substrate and retains mechanical and electrical properties even under larger deformation such as bending, twisting, etc. The liquid metal pattern can exhibit stretchability almost to same to that of the polymer substrate due to that the liquid metal is fully wetted on the substrate with metal patterns based on the wetting behavior of the liquid metal. Therefore, the stretchable circuit board can achieve both mechanical and electrical properties even under physical deformation such as bending, stretching and twisting. It is demonstrated that the stretchable circuit board can be effectively applied to wearable tactile interfaces, stretchable solar cell arrays, stretchable displays, and wearable electronic devices.

Abstract translation: 可伸缩电路板具有柔性基板的拉伸性和柔性，并且即使在诸如弯曲，扭转等的较大变形下也保持机械和电气性能。由于液态金属图案的拉伸性几乎与聚合物基材的拉伸性几乎相同， 液态金属基于液态金属的润湿性能，以金属图案完全润湿在基底上。 因此，即使在诸如弯曲，拉伸和扭曲的物理变形下，可拉伸电路板也可实现机械和电气性能。 可以证明，可拉伸电路板可以有效地应用于可佩戴的触觉界面，可拉伸的太阳能电池阵列，可拉伸的显示器和可佩戴的电子设备。
