1. An imaging device, comprising:
a two-dimensional array of piezoelectric elements, each piezoelectric element including:
a piezoelectric layer;
a bottom electrode disposed on a bottom side of the piezoelectric layer; and
a first top electrode disposed on a top side of the piezoelectric layer; and
an application-specific integrated circuit (ASIC) chip comprising an array of driver circuits for driving the two-dimensional array of piezoelectric elements, each of the driver circuits being electrically coupled to a corresponding piezoelectric element;
wherein the two-dimensional array of piezoelectric elements is arranged into columns of piezoelectric elements, a first column includes a portion of the piezoelectric elements of the two-dimensional array, and the first column is activated by simultaneously turning on a portion of the driver circuits that control the portion of the piezoelectric elements in the first column of the two-dimensional array.
