Fig. 4: The flexibility and filtering performance of 7-ACPECs.

a Photos of 7-ACPECs twisted and bent at different angles, such as, 0°, 60°, 120°, 180°and 360°, the scale bar is 2 cm. b Photo of 7-ACPECs being bent and worn on the wrist like a bracelet. c CV curves of 7-ACPECs under different deformation states (scan rate: 10 V s−1). d Plots of phase angle versus frequency of 7-ACPECs under different deformation states. e The filtering performance of 7-ACPECs under different deformation states. f The comparison of fluctuation amplitude of the output signals for 7-ACPECs under different deformation states with the commercial AEC. Inset shows the fluctuation signals of 7-ACPECs (0°) and AEC (47 μF/ 16 V, CHONGX, China). g The stability of the 7-ACPECs at the initial state (0°) for 15,000 cycles, and under bending at the angle of 180° for 20,000 cycles, then restoring to the initial state (0°) for 15,000 cycles.
