Abstract
This paper presents an innovative and versatile selective liquid-metal plating (SLMP) process to realize a transparent stretchable circuit board (TSCB) with the capability of large deformation and self-healing. The TSCB consists of polydimethylsiloxane (PDMS) thin films and non-toxic liquid-metal patterns that are embedded into the PDMS substrate. Complex liquid-metal patterns with various aspect ratios are achieved by using the selective wetting behavior of the reduced liquid metal on the Au/Cr patterns of the PDMS substrate. The smallest liquid-metal pattern is approximately 3μm in width. The TSCB integrated with a light-emitting diode exhibit stable performance, even though it is twisted more than 180° or is stretched up to ∼60% 6000 times. To evaluate the feasibility of the SLMP process, an electrical filter was fabricated on the PDMS substrate and the current–voltage (I–V) characteristics are successfully demonstrated under various conditions. The experimental results reveal that the proposed idea has the potential to enable advanced electronics such as wearable computers, wall-scale displays, electronic paper, and other stretchable electronics.
