What does the reverse piezoelectric effect refer to?

Sound is made from electrical energy

Mechanical deformation of materials

Change in shape of piezoelectric materials when voltage is applied

The reverse piezoelectric effect describes the phenomenon where piezoelectric materials undergo a change in shape when an electrical voltage is applied to them. This effect is central to the operation of ultrasound transducers. In these devices, the application of an electrical voltage causes the piezoelectric crystals to deform, leading to the generation of sound waves. This deformation is directly linked to the material's piezoelectric properties, which allow it to convert electrical energy into mechanical energy, resulting in sound production.

Understanding the reverse piezoelectric effect is critical for grasping how ultrasound machines create and transmit sound waves into the body, enabling the visualization of internal structures. This principle is foundational in the design and functionality of various medical imaging technologies.
