PIEZOELECTRICITY Meaning and
Definition
-
Piezoelectricity is a phenomenon or property exhibited by certain materials that have the ability to generate an electric charge when mechanical stress or pressure is applied to them. The term comes from the Greek words "piezo" meaning to squeeze or press, and "electrify" referring to the creation of an electric charge. In other words, when a piezoelectric material is compressed or deformed, it generates an electrical charge or voltage.
This unique property is attributed to the arrangement and structure of the crystal or ceramic lattice of piezoelectric materials, such as quartz, certain ceramics, and even some biological substances like bone and DNA. Within this lattice, positive and negative charges are distributed unequally, creating an imbalance. When mechanical stress is applied, the lattice is distorted, causing a displacement of the charges and the creation of an electric field. This electric field can induce a voltage across the material, which can be harnessed for various applications.
Piezoelectricity finds numerous practical applications across a wide range of industries. It is used in sensors and transducers to convert mechanical energy, such as pressure or vibration, into electrical signals. This is exploited in devices like microphones, ultrasound machines, and accelerometers. It is also utilized in actuators, which convert electrical energy into mechanical motion, such as in piezoelectric motors and inkjet printers. Piezoelectric materials are further employed in energy harvesting systems to generate electricity from ambient vibrations or movements. Overall, piezoelectricity plays a vital role in modern technology and continues to drive advancements in various fields.

Etymology of PIEZOELECTRICITY
The word "piezoelectricity" is derived from two Greek words: "piezo" (πιέζω), meaning "to press" or "to squeeze", and "electricity" (ἤλεκτρον), referring to the phenomenon of electric charge or electricity. The term was coined by French physicists Jacques and Pierre Curie in 1880 to describe the electric polarization of certain crystals when subjected to mechanical stress.
