High Efficiency Pzt Piezo Ceramic Plate For Humidification Beauty

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.

APPLICATION ANSWER

1.The frequency limit of apiezoceramic sheet and some properties?

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.

2.Is there any truth to piezo transducers being used as static and dynamic force sensors?

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.
