\n

The function of the ultrasonic transducer is to convert the input electric power into mechanical power (that is, ultrasound) and then transfer it out, and consume a small part of the power itself.<\/p>\n

Ultrasound transducer is widely used in industry, agriculture, transportation, life, medical treatment and military. According to the functions achieved, it can be divided into ultrasonic processing, ultrasonic cleaning, ultrasonic detection, detection, monitoring, telemetry, remote control, etc. According to the working environment, it can be divided into liquid, gas, organism, etc. According to the nature, it can be divided into power ultrasound, detection ultrasound, ultrasonic imaging, etc.<\/p>\n<\/div>

Ultrasound Weight Loss<\/h3><\/div>
<\/div>
\n

Using the cavitation effect of ultrasonic transducer and micromechanical vibration, the excess adipocytes under human epidermis are crushed and emulsified and discharged from the body to achieve the purpose of weight loss and shaping. This is a new technology developed in the 1990s. Zocch i, Italy, first used ultrasound degreasing in beds, and achieved success, pioneering plastic and cosmetic surgery. Ultrasound degreasing technology has developed rapidly at home and abroad.<\/p>\n

Electronic Sphygmomanometer<\/h3><\/div>
<\/div>
\n

Ultrasound transducer receives the pressure of blood vessel. When the balloon compresses the blood vessel, the pressure of blood vessel can not be felt by the ultrasonic transducer because the external pressure is higher than the diastolic pressure. When the balloon is gradually deflated and the pressure of the ultrasonic transducer on the blood vessel decreases to a certain value, the pressure of the two transducers reaches a balance, and then the pressure of blood vessel can be felt by the ultrasonic transducer. Pressure is the systolic pressure of the heart, which is indicated by the amplifier and the blood pressure is given. The electronic sphygmomanometer can reduce the labor intensity of medical staff because of the cancellation of stethoscope.<\/p>\n<\/div><\/div><\/div>

Ultrasound Breeding<\/h3><\/div>
<\/div>
\n

The appropriate frequency and intensity of ultrasound irradiation on plant seeds can improve the germination rate, reduce the mildew rate, promote the growth of seeds, and increase the growth rate of plants. According to the data, ultrasound can increase the growth rate of some plant seeds by 2-3 times.<\/p>\n<\/div><\/div><\/div>

Telemetry and Telecontrol<\/h3><\/div>
<\/div>
\n

In toxic, radioactive and other harsh environments, people can not get close to work and need remote control; TV sets, fans and electric lights and other electrical switches need remote control, can be equipped with ultrasonic transducers, through the remote transmission of ultrasound by the receiving transducer installed on the need control system to receive, the sound signal into electrical signals to make the switch operate.<\/p>\n<\/div><\/div><\/div>

Traffic Monitoring<\/h3><\/div>
<\/div>
\n

In modern traffic, it is very necessary to automatically monitor the traffic and counting of vehicles in order to grasp the operation of vehicles. If the traffic supervision station installs an ultrasonic transducer and its auxiliary equipment, when the vehicle passes, there will be a sound pulse to return, and the number of daily vehicles can be accumulated by counting. Installing a transducer for both sending and receiving at the rear of the car can prevent backing collision. The noise index can also be monitored by installing a receiving piezoelectric ultrasonic transducer on the highway.<\/p>\n<\/div><\/div><\/div>

Ultrasonic Leak Detection and Gas Detection<\/h3><\/div>
<\/div>
\n

(also known as Non-destroy Test or NDT)<\/p>\n

For the pressure system, the jet noise is caused by the pressure difference between the inside and outside of the pressure vessel at the leakage site. The noise spectrum is very wide. For the non-pressure system, an ultrasonic source can be placed in the closed system, and then received from the outside of the closed system. Generally, the signal amplitude measured without leakage is very small or not, and there is a sudden increase in the signal amplitude at the leakage site. Gas flow detection is also one of the important means in chemical industry. At present, there are many kinds of amplification in flow detection, such as float flowmeter. But the main advantage of using ultrasonic transducer is that it does not hinder the flow of fluid.<\/p>\n<\/div><\/div><\/div>

Ultrasonic Distance Measurement<\/h3><\/div>
<\/div>
\n

The ultrasonic distance measurement device is also called a sound ruler. It measures the pulse time interval through a dual-purpose transducer. The sound ruler can measure the distance within 10m, and the accuracy can reach several thousandths.<\/p>\n<\/div><\/div><\/div>

Information Acquisition<\/h3><\/div>
<\/div>
\n

In order to realize the functions of walking freely in space and recognizing objects, intelligent robots not only need to use ultrasonic transducer to measure distance and guide blindness, but also need image recognition. Therefore, we need a small ultrasonic transducer array to achieve a variety of functions, which will become an important research topic and attract many scientists to strive for it.<\/p>\n<\/div><\/div><\/div>
