(a) Schematic diagram of the LS-mode TENG with displacement x=0 and x=xmax. (b) The CEO with load resistance R=100 MΩ. The total cycling charge QC was marked and the inset shows the operation circuit. (c) The steady-state of CEO with various load resistances. (d) The CMEO with load resistance R=100 MΩ, with the maximum total cycling charge QC=QSC,max. The insets show the corresponding status of the switch in circuits during different steps. (e) The CMEO with various load resistances. The vertices of the CMEO with infinite load resistances are marked.
