a The VOC and ISC of i-eMEH with different area. b The VOC of i-eMEH array with different serial number. Each i-eMEH unit is 1 × 1 cm. c The ISC of i-eMEH array with different parallel number. Each i-eMEH unit is 1 ×1 cm. d Voltage-time curve of commercial capacitors (4 F) charged by 4 × 2 i-eMEH arrays (4 in series and 2 in parallel) under quasi-continuous output (10 s/20 min). Inset exhibits the circuit connection diagram and the enlarged voltage-time curve in single cycle of quasi-continuous output. The inset axes share the units of the main figure. e Optical image of the commercial electric fan (JISULIFE LA19) actuated by a lithium battery LIR1025 charged by 7×6 i-eMEH arrays. Scale bar: 3 cm. f Optical image of the flexible circuit composed of a resistance, capacitor (220 μF), four i-eMEH units (0.25 cm2) connected in series, and an LED light bead. Scale bar: 1 cm. g The voltage-time curve of the capacitor (220 μF) on flexible circuit charged by 4 × 1 i-eMEH array (1 cm2). Inset depicts the LED light in the off and on states, respectively.
