a Schematics of the fabrication process (from top to bottom): laser patterning of rGO on a glass substrate, deposition of an Au layer leading to the formation of rGO/Au heterostructures, transfer of rGO/Au to a PDMS elastomer, and assembly of rGO/Au/PDMS MSCs with a PVA/H2SO4 gel electrolyte. The photos show examples of MSCs printed in digital images and demonstrate their wearability by means of embedding on a long-sleeved glove or a mug and their use to power a digital watch or a blue LED. b Top-view (left) and tilted-view (right) scanning electron microscopy (SEM) images and photos (insets) corresponding to three fabrication schemes: rGO/glass, Au/rGO/glass, and rGO/Au/PDMS. Scale bars: 300 μm (top views), 30 μm (tilted views), and 5 mm (insets)
