Extended Data Fig. 3: SEM images of the AgNWs-coated origami.
From: Active mechanical haptics with high-fidelity perceptions for immersive virtual reality
SEM images of AgNWs coated on the surface of a PET film under initial (a), outward (b), and inward (c) bending at low (up) and high (bottom) magnitude. The scale bars are 2 μm (in yellow) and 1 μm (in red), respectively. Outward bending shows loosely packed structure, while inward bending shows densely packed structure, as compared with the initial state, indicating resistance increase for outward bending and decrease for inward bending.
