Pzt Piezo Ceramic Plate For Humidification Beauty Application
Piezoelectric ceramic materials are electromechanical transducers: They can convert mechanical energy into electrical energy and vice-versa. Piezoelectric ceramic material from us are used in sensors, actuators, gas ignition and in power transducers for high-power ultrasonic applications.

Scientists refer to the number of vibrations per second as the
frequency of the sound, and its unit is Hertz (Hz). The frequency
of sound waves that our human ear can hear is 20Hz-20000Hz.
Therefore, we call sound waves with a frequency higher than 20,000
Hz as "ultrasonic waves." Ultrasound frequencies commonly used for
medical diagnosis are 1 MHz to 30 MHz.
Theoretical studies show that under the same amplitude conditions,
the vibration energy of an object is proportional to the vibration
frequency. When ultrasonic waves propagate in the medium, the
frequency of the medium particle vibration is very high, and
therefore the energy is very large. In the dry winter in northern
China, if The ultrasonic waves into the water tank, the violent
vibration will make the water in the tank broken into many small
droplets, and then use a small fan to blow the fog into the room,
you can increase the indoor air humidity, which is the principle of
ultrasonic humidifier. Such as pharyngitis, bronchitis and other
diseases, it is difficult to use the blood flow to the drug to
reach the site of the disease, the use of the principle of
humidifier, the liquid atomized, let the patient inhale, can
improve the efficacy. Utilizing the enormous energy of ultrasonic
waves can also cause the stones in the body to be broken by violent
vibration, thereby slowing the pain and achieving the goal of
healing. Ultrasound is widely used in medicine and can sterilize
items.
Usually the frequency limits of applications are ascertained through the resonances involved with the transducer design and its size and shape. For a piezoceramic sheet, there is no limit for inherent frequency. A sheet of PSI-5A material which is 2.85″ square, .0075″ thick has planar dilatation mode of about 14 KHz and of 13 MHz of thickness mode vibration in the neighborhood. Limiting factors can arise such as the resistive heating of electrodes when considerable current is gathered at large surface area parts during ultrasonic frequencies.
Due to charge leakage the Piezo transducers cannot be used for static force measurements. For transient force measurements they can be applied successfully for only0.1 second.
3.The expected life of piezoelectric material?
There are no tests yet that can determine the “fatigue life”. Our facility has had an operational piezo fan since 1982. Such calculations must involve voltages and mounting.
4.How does temperature effectpiezoceramic transducers?
The pyroelectric properties of piezoceramic are responsible for the appearance of voltage through the any piezo transducer electrodes due to temperature changes. Almost each and every property of piezoceramics is affected by temperature. There exists no general manner regarding it. In accordance to your experiment and calculations, the dependence must be looked upon in that context.
Company introduction:
Established in 1999, Beijing Cheng-cheng Weiye Science and Technology Co., Ltd is a professional manufacturer in ultrasonic transducers, ultrasonic equipment and piezoelectric ceramics.
Notably in 2004, we researched and developed our ultrasonic tubular transducer equipment into a new product that turns the extreme inconvenience brought about by pipeline and vacuum cleaning into an easy task.
