Current and Voltage for a Series-Parallel Configurations of Piezoelectric Transducers Dataset

The piezoelectric elements used are arranged in two test configurations for the experiments: a series electrical connection of two units and a parallel electrical connection of two units, while remaining mechanically isolated. It is important to emphasize that although the elements are electrically connected, they are not mechanically coupled. Data collection focuses on two input variables—oscillation frequency and load resistance—with the output being the voltage across the piezoelectric elements and the current through the load. The experiments involve frequency sweeps from 0 to 200 Hz in 1 Hz increments and load resistance sweeps, fixed at 5 kΩ and ranging from 10  kΩ  to 300 kΩ.
