piezoaktiivsed

Piezoaktiivsed refers to materials that exhibit the piezoelectric effect. This phenomenon involves the generation of an electric charge in response to applied mechanical stress, or conversely, the deformation of the material when an electric field is applied.

Materials that are piezoaktiivsed can be broadly categorized into natural and synthetic types. Natural piezoaktiivsed materials include certain crystals like quartz and Rochelle salt. Synthetic piezoaktiivsed materials are often ceramics, such as lead zirconate titanate (PZT), or polymers like polyvinylidene fluoride (PVDF). The choice of material depends on the specific application requirements, including sensitivity, operating temperature, and cost.

The applications of piezoaktiivsed materials are diverse. They are used in sensors to detect pressure, vibration, and acceleration. In actuators, they are employed to create precise movements, such as in inkjet printers, fuel injectors, and ultrasonic transducers used in medical imaging and sonar. They also find use in energy harvesting devices, converting mechanical vibrations into electrical energy. The study and development of piezoaktiivsed materials continue to be an active area of research, aiming to improve their performance and explore new applications.
