"six-layer, 1.5-inch square flexible display, in which the electrodes, interconnects, insulation, and encapsulation were extrusion-printed... potential in soft electronics and wearables, this one-pot methodology allows for other unique form factors beyond the typical 2D layout... maintained high electrical conductivities, such as silver-based inks for our electrodes. For the encapsulation, we used a common transparent and flexible polymer, PDMS, to coat the device on top"
