What is piezoelectric efffect?5 answersThe piezoelectric effect is the ability of certain materials to generate an electric charge in response to applied mechanical stress, or to deform in response to an applied electric field. It was first discovered by Pierre and Jacques Curie and has since been observed in various materials, including solid-phase materials such as quartz and ionic crystals like alpha-quartz. The direct piezoelectric effect refers to the production of charge upon the application of force to a material, while the converse piezoelectric effect refers to a change in the material's dimensions upon the application of a potential. The effect is based on the induction of dipole electric moments in the crystal structure, resulting in polarization charges. Piezoelectric materials play a crucial role in microelectronic devices and have applications in sensor and actuator technologies.
