Lead zirconate titanate (PZT) microwires with applications in sensors, actuators, and energy harvesters are produced using hydrothermal synthesis. The synthesized microwires are relatively large with an average length of about 450 microns and an average width of 4 microns. Each of these individual PZT microwires can be integrated in smart systems as an active phase or be used as an independent smart material. In this paper, the synthesis procedure and characterization of these large microwires is demonstrated. The converse piezoelectric properties of the microwires are measured using digital image correlation after clamping and adding electrodes at each end of the microwire. It has been shown in the literature that digital image correlation can be used as a precise tool for rapid characterization of piezoelectric materials. Here, it is demonstrated that this technique can be applied to characterize the actual response of piezoelectric materials at the micron scale.
