Piezoelectricity is a physical property exhibited by certain materials that produce an electric charge when subjected to mechanical stress. This phenomenon occurs due to the specific crystalline structure of piezoelectric materials, which enables the conversion between mechanical and electrical energy. The term originates from the Greek word “piezein,” meaning to press or squeeze, reflecting the direct relationship between applied pressure and electrical generation.
Materials demonstrating piezoelectric properties include quartz crystals, lead zirconate titanate (PZT) ceramics, and polyvinylidene fluoride (PVDF) polymers. The mechanism of piezoelectricity involves the displacement of electric dipoles within the material’s crystal lattice structure. When mechanical stress is applied, these dipoles shift position, creating a net electric polarization that produces an electric field across the material.
This process is reversible: applying an electric field to a piezoelectric material causes mechanical deformation. This bidirectional energy conversion capability has resulted in applications across multiple industries, including pressure sensors, ultrasonic transducers, precision actuators, and mechanical energy harvesting systems.
