Figure 5. Characterization of electromechanical conversion of different piezoelectric films. (A) Schematic illustration of a custom-made piezoelectric test station; (B) electromechanical conversion in terms of applied force vs. output voltage of films normalized with 10-μm thickness; and (C) changes in output voltage over 5000 cycles using a repeated force of 0.2 N.
