    Properties of piezoceramics

    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 piezoelectric element is characterized by the following properties:

    a) Relative dielectric constant b) Resonance frequency c) Electromechanical coupling constant d) Elastic constant

    a) Relative dielectric constant

    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

    b) Resonance frequency

    The natural frequency f0 of the plate by thickness calculated by the fllowing formula

    c) Electromechanical coupling constant

    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

    d) Elastic constant

    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.

    Applications for Piezo Ceramic Element

    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.

      Piezo Element quality identification: A mechanical multimeter can easily detect whether the piezoelectric element is good or bad. The method is as follows: Set the multimeter to 25V, gently pinch the two sides of the piezoelectric plate with your left thumb and index finger, and hold two test pens in your right hand. Press it down, then relax, and the piezo element will generate two voltage signals with opposite polarities successively, so that the pointer swings to the right - back to zero - left - back to zero, with a swing of about 0.1~0.15V. If you re-test after changing the position of the test leads, the sequence of pointer swing is left swing - zero return - right swing - zero return. Under the same pressure, the larger the pointer swing, the higher the sensitivity of the piezoelectric element. If the pointer does not move, it means that the acoustic element is leaking or damaged. The appearance should be free of scratches and fingerprints. The ceramic sheet is not eccentric. The ceramic sheet and the substrate are bonded perfectly without overflowing glue,

    • 35mm 2.6KHZ frequency external piezo ceramic element


      Can the piezo element sound alone? many customer ask this kind of questions,but we answer as below:the piezo film is made into a very thin original film, and the sound cannot be produced without a resonant cavity. Even the sound is small and can only be heard in a very quiet environment. And only when the piezoelectric honeycomb has a resonant cavity, it can make a loud sound after power-on, even in a noisy environment. For example, the piezo sounder and the shell can be turned into a buzzer or an alarm, which can emit different sounds as required by customers. Therefore, it is not meaningful to say the volume of the sound emitted by the buzzer alone, and the volume must be determined with the cavity. But generally speaking, the bigger the internal type piezo element and the bigger the shell, the louder the sound! This information comes from FBelec's engineering department

      Common problems of piezoelectric diaphragms: Today, let's talk about the common quality problems of buzzer films, so as to facilitate your purchase and distinguish the quality. 1. Part of ceramic disc of buzzer film falls off: First: there is a problem with the glue of buzzer tablet. The glue quality is poor or the amount of epoxy resin adhesive is not enough Second: copper or steel sheet, nickel alloy sheet bending deformation. Third: when the ceramic sheet and substrate are bonded, the curing temperature and time are not enough or too much. 2. piezoelectric ceramic disks has no sound: First: piezoelectric ceramic vibrating plate (silver plate) is not polarized Second: the piezoelectric ceramic vibrating plate (silver plate) is dark cracked, and the positive / negative pole of the silver plate is short circuited. Third: the piezoelectric ceramic vibrating plate (silver plate) is not bonded and cured well with the metal plates. FBelec avoid above problem in order to guarantee the quality for customers.

  • Diâmetro 20milímetros 6.5KHz elemento cerâmico piezo de latão


    Piezoelectric element is a piezoelectric ceramic plate which is pasted on the vibrating metal plate after high pressure extreme pressure. When the ac voltage is added, the piezoelectric effect will cause mechanical deformation, stretching and contraction, and the use of this feature to make the metal sheet vibration and sound. 1. Peripheral support mode - the outer diameter edge of the buzzer piece is fixed in the resonance cavity. Generally, no feedback piezoelectric sensor is adopted, and the Piezoelectric Disk must be matched with the frequency of the resonance cavity to have a high sound pressure output, and the external oscillation circuit generates a driving signal to make the buzzer sound. 2. Node support mode - the buzzer plate is fixed in the annular structure of about the same size as the diameter of ceramic plate. If the resonator cavity is properly designed and matched with the correct frequency feedback piezoelectric diaphragms and positive feedback circuit, the sound pressure and correct frequency can be generated.
