Stretchable dual-capacitor sensor composed of AgNW electrodes and PDMS insulators. (a) Schematic view of the fabrication processes of dual-capacitor sensor which has two capacitors stacked vertically. (b) The schematic view of dual-capacitor sensor during curvature sensing when the sensor is in convex shape with the curvature radius of r. Photographic image of 5 × 5 array type dual-capacitor sensor (c) bent in convex shape and (d) stretched by hand.
