Abstract

The peak output voltage (VL) of polyvinylidene fluoride (PVDF) piezoelectric devices has been investigated as a function of load resistance (RL). Two identical piezoelectric devices were mounted, back to back, on a vibrating cantilever giving almost similar VL. Using RL values in the range of 4.6 KΩ to 1 MΩ, it was observed that VL was doubled when the devices were connected in parallel but it did not change when the devices were connected in series. For single, parallel and series configurations, VL increases linearly with increasing RL. These results are explained well by modeling the device as a discharging capacitor with internal source of charge generation.
