• current output. The piezoelectric potential generated in the ZnO nanosheets functions as an applied voltage, facilitating charge storage within the LDH layers, which act as capacitors. This mechanism leads to enhanced voltage and current pulses under mechanical stimulation. LDHs can also enhance the

• charge grows with increasing deformation, but the peaks of boundary electric charge do not appear at the cross-section endpoints. Thus, in order to effectively improve the performance of the ZNW nanogenerator, the effect of electrode configuration on the piezoelectric potential difference and output

• -axis; piezoelectric potential; semiconductor; zinc oxide (ZnO); Introduction An acoustic wave propagating in piezoelectric semiconductors usually stimulates electric fields that bring charge carriers into motion, and conversely, the carrier motion will produce an opposite effect on the electric fields

• vertically aligned ZnO nanowires [18][19][20][21][22][23][24][25][26][27]. The principle of nanogenerators is that the piezoelectric potential produced by the piezoelectric effect can produce a current in an external circuit when the ZNW is deformed. Specifically, a transversely applied force makes the
