PIEZOELECTRICS Meaning and
Definition
-
Piezoelectrics refers to a specialized class of materials that exhibit the piezoelectric effect, which is the ability of certain materials to generate an electric charge in response to applied mechanical stress or deformation. This unique property arises from the inherent crystal structures of piezoelectric materials, which possess an asymmetry that allows for charge separation when subjected to mechanical force.
When a piezoelectric material experiences mechanical deformation, such as compression or bending, it causes positive and negative charges on opposite faces of the material to shift relative to each other. This charge separation leads to the development of an electric field or voltage across the material. Conversely, when an electric field is applied to a piezoelectric material, it impacts its shape or causes a mechanical response.
Piezoelectric materials find application in various fields such as sensors, actuators, and transducers due to their ability to convert mechanical energy into electrical signals and vice versa. They are utilized in devices such as ultrasound transducers, inkjet printers, vibration sensors, sonar devices, acoustic emission detectors, and more.
Crystals like quartz, tourmaline, and ceramics like lead zirconate titanate (PZT) are commonly used as piezoelectric materials due to their high piezoelectric coefficients and stability. Research continues to explore new materials and improve existing ones in order to enhance the efficiency and range of applications for piezoelectric materials in emerging technologies such as energy harvesting, biomedical devices, and electronic devices.

Etymology of PIEZOELECTRICS
The word "piezoelectric" has its roots in two Greek words: "piezo" meaning to squeeze or press, and "electric" referring to electricity. This term was coined in 1880 by French physicists Jacques and Pierre Curie to describe a phenomenon where certain materials generate an electric charge when subjected to mechanical stress or pressure. The word combines these two concepts to describe the interaction between mechanical forces and electrical charge, characteristic of piezoelectric materials.
