Piezoelectric ceramic element, commonly known as piezo buzzer element . Piezo electric elements sheet is an electronic element that make sound. Piezoelectric ceramic dielectric material is placed between two copper circular electrodes. When AC audio signal is connected on the two electrodes, the piezoelectric sheet will vibrate according to the size and frequency of the signal and produce corresponding sound. Because of its simple structure and low cost, piezoelectric ceramics are widely used in electronic and electrical appliances , such as pronunciation electronic watches, electronic instruments, electronic clocks, timers,toys, etc.

The relationship between the applied force and the resuting response of the piezoelectric element depends on: the piezoelectric properties of piezoceramic, the size and shape of the sample, the direction of electrical and mechanical excitation.
By their nature, piezoelectric materials are anisotropic crystals. Figure 3 shows the different directions and orientation axes of the piezoelectric material. Axes 1, 2 and 3 are the corresponding analogs of the X, Y, Z axes of the classical orthogonal coordinate system, while the axes 4, 5, and 6 define the axes of rota- tion. The direction of axis 3 is the direction of polarization This direction is established during production by means of a high constant voltage that is created between the electrodes.
The relative dielectric constant is the ratio of the dielectric permittivity of the material (in this case E33T and E11T) to the dielectric permittivity of a vacuum
The natural frequency f0 of the plate by thickness calculated by the fllowing formula
The electromechanical coupling coefficients kp, k33, k15, kt and k31 describe the ability of the piezoelectric element to convert energy from electrical to me- chanical and vice versa.The square of the electromechanical coupling coefficient is defined as the ratio of the accumulated converted energy of one type (mechanical or electrical) to the input energy of the second type (electrical or mechanical). The index shows the relative directions of electrical and mechani- cal quantities and the type of oscillations. They can be associated with the mode of oscillations of a simple transducer
The elastic properties of piezoelectric materials are characterized by elastic compliance (elastic compliance) or elastic siffness (elastic siffness). Elastic com- pliance determines the amount of strain due to an applied mechanical stress. Due to the fact that under the infuence of mechanical stress, the ceramic gen- erates an electrical response, which counteracts the resultant strain, the effective Young's modulus for a short circuit of electrodes is less than open circuited.
Piezoelectric materials have found application in a wide range of areas, such as medical instruments. control of industrial processes, semiconductor manu- facturing systems, household electrical appliances, communication control systems, various measuring instruments, and other areas. Commercial systems that use piezoelectric materials - pumps, sewing machines, sensors (pressure, icing, angular velocities, etC.), optical instruments, laser printers, motors for autofocus cameras, and many others. In this case, the scope of these materials is constantly growing. Using a piezoelectric element is usually reduced to four categories: sensors, generators, power actuators, and transducers.
In generators, piezoelectric materials can generate a voltage suflcient to cause a spark between the electrodes, and thus can be used as electrodes to ignite the fuel, for gas stoves and for welding equipment. Altermatively, the electrical energy generated by the piezoelectric elements may accumulate. Such genera-tors are excellent solid batteries for electronic circuits.
In sensors, piezoelectric materials convert physical parameters such as acceleration, pressure, and vibrations into an electrical signal. In actuators, piezoelectric materials convert an electical signal into a precisely controlled physical displacement, clearly setting the accuracy of mechanical tools, lenses, and mirrors.
