A copper tape was first loaded in a paper-cutting machine (Silhouette CAMEO 3). The electrical circuits were first designed with computer-aided design and loaded to the machine via Silhouette Studio software. After completion of the cutting, the copper tape was placed on a flat acrylic plate and unwanted parts were carefully peeled off. Two additional conductive wires were soldered on the copper tape as two electrodes. An electrical generator (Instek PSB-2400L2, TEquipment) was used to apply controlled current around 2 to 5 A on the designed circuits. To ensure that the designed temperature was achieved, a thermal imager (Seek Thermal XR imager) was first used to measure the local temperature from the circuit (see fig. S9). By adjusting the current to control the designed temperature, the air-dried PVA hydrogel was placed on the targeted circuits for local heating. A gripper was used to ensure full contact between the PVA films and copper circuits.
