Fabrication process and morphology characterization of the micropatterned electrodes on the Polydimethylsiloxane (PDMS) substrates. (a) Fabrication process of the PDMS electrode with the Ag-embedded pyramid structure; (b) scanning electron microscopy (SEM) image of the electrode with a one-dimensional pyramid structure showing high uniformity; (c) Laser confocal image of the electrode pattern; (d,e) SEM image of the micropatterned electrodes on the PDMS substrates after replication from the same Si mold.
