NI 6070E functions as an interface between hardware component and software LabVIEW was used to acquire, process, and store the data. Fig. 10 presents a schematic of the data acquisition setup.The initial load applied on the transducer was 5 N, then was increased to 100 N in a step increment of 5 N. The linear calibration curve obtained from the compression load and sensor output(average of three trials) are shown in Fig. 11. The result was used to obtain the effective piezoelectric coefficient along the longitudinal direction, i.e. d33 eff, as around 6.48 pC/N.
