Figure 2. Mechanical activation of circuits prepared from the liquid metal slurry. (A) Schematic diagram of the mechanical activation mechanism of circuits consisting of numerous stacked liquid metal particles; (B) Optical image of unactivated liquid metal traces and their scanning electron microscope (SEM) image. Scale bar: 5 mm, 50 μm; (C) Optical image of liquid metal traces activated by scratching and SEM image of their surface topography. Scale bar: 5 mm, 100 μm; (D) Optical image of liquid metal traces activated by stretching and SEM image of their surface topography. Scale bar: 5 mm, 50 μm. SEM: Scanning electron microscope.
