The piezoelectric properties of a transducer are critical for its function in medical imaging. These properties allow the transducer to convert electrical energy into mechanical energy (sound waves) when transmitting, and then convert the returning mechanical energy back into electrical signals to create images. Improper handling of the transducer can lead to physical damage or material degradation that can compromise these piezoelectric characteristics. For instance, excessive force, exposure to extreme temperatures, or improper cleaning methods might disrupt the molecular arrangement of the piezoelectric material, leading to a loss in performance.

Understanding the piezoelectric properties' significance highlights how they must be preserved to keep the transducer operational. In contrast, while other properties such as stability, electrical impedance, and rigidity are essential, they may not be as directly affected by handling as the piezoelectric properties.
