Testing Function
In the characterization of piezoelectric polymer, composite, and iontronic energy-harvesting systems, open-circuit voltage (Voc) and short-circuit current (Isc) represent the two fundamental intrinsic output figures of merit. Our testing platform evaluates dynamic voltage, current, and transferred charge under ultrasonic wave excitation (1 MHz), electrodynamic shaking (100–300 Hz), and cyclic motor loading (DC–20 Hz, 0.3–100 N), delivering rigorous fatigue degradation curves and power density plots.
