Ceramic sheet is the most common shape for piezoelectric components, easy to process and control in size. They are typically used in applications where they can operate under non-resonance conditions, such as sensors and energy harvesters, as well as in high-frequency resonant states, such as ultrasonic transducers.

The piezoelectric plate is particularly advantageous in applications that require unidirectional force or displacement. 

The piezoelectric disc provides radial symmetry, enabling uniform stress distribution.
