a, b Digital photograph and analog signal transmission of 6-channeled organogel-based or hydrogel-based PCBs connected to conventional rigid PCBs through ZIF connectors. c Digital photograph of CP-PVA organogel-based digital wristband containing 8 pairs of electrodes for electrophysiological signal recording. sEMG signals recorded with the organogel-based digital wristband during the performance of four different gestures (gestures I, II, III, V) (d); sEMG maps corresponding to the four-hand gestures were generated by calculating the root mean square (RMS) amplitude for each channel (e). Digital photograph of reconfigurable organogel-based EL devices (f) and LED bands (g): The EL devices and the LED bands were powered by an alternating current voltage of 100 V at 1 kHz and a direct current of 20 mA, respectively. h Digital photograph of a stretchable circuitry model based on an organogel PCB for audio playing, consisting of resistors, capacitors, switches, an LED, a speaker, and an FLM038A integrated circuit (IC). The audio player circuitry model was highly soft and operable upon strain. Unless otherwise specified, CP-PVA organogels with a solid content of ~50 wt% (relative to the total mass of organogels) and CP’s content of 22 wt% (relative to the total mass of CP and PVA) were used for the experiments here.
