Stretchable electronics have attracted much more attention in recent years due to their excellent conformability to non-planar objects and potential applications in wearable electronics, flexible display and bioengineering. In this work, a fast and efficient method has been developed for fabrication of stretchable electrodes with complex pattern by printing assisted vacuum filtration. The linewidth of the patterned Ag NWs electrodes is down to 50 μm, and the enlarged SEM image shows the Ag NWs line with well defined sharp edge. The microelectrode array on the silicon substrate has excellent uniformity of resistance, and the stretchable electrode is also very stable under repeated strain condition. It is shown that the resistance increases only 40% when the tensile strain is doubled. The buckling structure of Ag NWs/PDMS composite layer results in the resistance stability under strain condition. Also demonstrated is the stretchable lighting circuit integrated on textile for wearable application.
