An ultrasonic sensor or a probe generates sound waves, and the reflections of the sound waves produce clear images of body tissues and organs, which is an important part of the ultrasound system. The following are the three most common ultrasonic probe types: Linear Probes As the name suggests, there is a linear piezoelectric structure. The beam shape is rectangular, and the near-field resolution is higher than average. Depending on the clinical application, the frequency, footprint, and application of the linear probe are likely to vary. The probe used for 2D imaging has a wide coverage range, and its broadband frequency is 5-20 MHz. It is used to examine the breast, thyroid, tendons and blood vessels, and to measure the thickness of carotid artery disease. Convex ultrasound probe Also commonly called a curved probe, there is a curved piezoelectric crystal arrangement, and the beam is convex. The probe used for 2D imaging has a wide coverage range, and its broadband frequency is about 2.5 MHz-7.5 MHz, which can be used for abdominal and vaginal examinations. The probe used for 3D imaging has a wide field of view, and its broadband frequency is 3.5 MHz-6.5 MHz. 3D bending probes usually use electromechanical moving parts in the head, and are usually used to diagnose pregnancy abnormalities. Phased array ultrasound probe The phased array ultrasound probe is so named because the crystals are arranged in a "stacked" structure. The beam is very narrow, close to a triangle, and the near-field resolution is poor. This kind of probe has a small footprint and a broadband frequency of 2-6 MHz. It is mainly used for cardiac and transcranial examinations. Other types of ultrasound probe Such as the pencil type, intracavity type and transesophageal type, all have a specific purpose: to check blood flow, internal cavity and heart respectively. Some probes, such as laparoscopic probes, are specifically designed for surgical procedures.

There are two methods of classification of transducer and classification according to the marking method of the USG transducer symbols. One is classified by the working principle, and the other is classified by the amount of detection. According to the working principle, there are strain transducers, capacitive transducers, inductive transducers, piezoelectric transducers, magnetoelectric transducers, pyroelectric transducers and photoelectric transducers. In addition to the common classification methods of the USG transducer, there are various classification methods based on transducer material, transducer structure, energy conversion fraction, etc. All of them have their advantages and limitations. 1. The medical USG transducer can be distinguished by detection According to detection, the medical USG transducer can be divided into displacement transducer, flow transducer, temperature transducer, speed transducer, pressure transducer, etc. As for pressure transducers, there are metal strain gauge pressure transducers, semiconductor pressure transducers, capacitive pressure transducers and other USG transducers that can detect pressure. In terms of the temperature transducer, there are thermistors, thermocouples, PN junction temperature transducers and other USG transducers that can detect temperature. 2. The transducer in medical can be classified according to the human senses that can be replaced The USG transducer can be classified according to the human senses that the USG sensor can replace. For example, vision transducers include various optical transducers and other USG transducers that can replace vision functions. Auditory transducers include various pickers, piezoelectric transducers, capacitive transducers, and other USG transducers that can replace auditory functions. Olfactory transducers include various gas-sensitive transducers and other USG transducers that can replace olfactory functions.

1. Introduction of the wireless ultrasound transducer The ultrasonic waves emitted by the wireless ultrasound transducer are also known as mechanical waves, which have good directionality, strong penetrating ability, and the ability to spread in water and air. The wireless ultrasonic transducer can be used for distance measurement, speed measurement, cleaning, welding, stone crushing, sterilization, disinfection, etc. Based on the vibration excitation mode, transducers commonly used in ultrasound can be divided into magnetostrictive transducers and electrostrictive transducers. At the beginning of the 20th century, the development of electronics enabled people to make various electromechanical transducers by using the piezoelectric effect and magnetostrictive effect of certain materials. In 1917, people made sandwich-type ultrasonic transducers with natural piezoelectric quartz and used them to explore submarines on the seabed. With the continuous development of ultrasonic applications in various military and economic sectors, magnetostrictive transducers with greater ultrasonic power have emerged, as well as various types of ultrasonic transducers with different purposes such as electric, electromagnetic, and electrostatic transducers. 2. Application of the wireless ultrasound transducer in medical treatment The application of the wireless ultrasound transducer in medical treatment is mainly divided into medical testing and medical treatment. As you commonly see in hospitals, medical instruments that we can commonly see such as B-ultrasound, color doppler ultrasound, ultrasonic holography technology, ultrasound scalpel, and ultrasound crushing technology all use the wireless ultrasound transducer to work. The working principle of medical ultrasound is similar to that of sonar. When the ultrasonic wave emitted into the human body will be reflected and refracted when they encounter interfaces, and it will be absorbed and attenuated by the human body so that there is no harm to human body tissues. The wireless ultrasound transducer is used in different medical devices with different purposes. Also, the wireless ultrasound transducer is widely used in the medical industry because it is not harmful to the human body.

Steel fiber reinforced concrete (SFRC) is a kind of heart-shaped composite material with excellent performance and wide application. Steel fiber retards the crack development of matrix concrete, which makes it tensile and flexural. Compared with ordinary concrete, the shear strength is significantly improved, and its impact resistance, fatigue resistance, toughness, and durability after cracking are also greatly improved. In recent 20 years, a lot of research has been done on the mechanical and structural properties of steel fiber reinforced concrete at home and abroad, and it has been applied to variousteel_fiber_for_concrete_reinforcement.p , ngs projects such as roads, bridges, tunnels, water conservancy, oceans, buildings, and refractory structures. Reinforcement effect of steel fiber in concrete, The main function of short fibers randomly distributed by steel fibers in concrete is to hinder the propagation of micro-cracks in the concrete and to retard the occurrence and development of macro-cracks. Therefore, it can obviously improve its tensile strength and shear, bending, and torsional strength mainly controlled by principal tensile stress. When the fiber content (volume ratio) is in the range of 1%-2%, the tensile strength increases by 25%-50%, the bending strength increases by 40%-80%, and the shear strength measured by direct double-sided shear test increases by 50%-100%.

Fatigue resistance of steel fiber compared with ordinary concrete, the flexural and compressive fatigue properties of steel fiber reinforced concrete are greatly improved. For example, when the bending fatigue life is 106 times, the stress ratio of steel fiber reinforced concrete with 1.5% fiber content is 0.68, while that of ordinary concrete is only 0.51. When the stress ratio is 0.7, the bending fatigue life of steel fiber reinforced concrete exceeds 105 times, while that of ordinary concrete is only 850 times. Another example is: when the compressive fatigue life of steel fiber reinforced concrete with 2% fiber reaches 2*106 times, the specific force can reach 0.92, while the stress ratio of ordinary concrete is only 0.56. It can be seen that the use of steel fiber reinforced concrete can significantly improve its fatigue life in projects bearing fatigue loads such as pavement and pier.

The Working Principle of Steel Fiber Fibers reinforce in three dimensions throughout the entire concrete matrix. Fiber performance is based on the combination of the tensile strength, aspect ratio(length/diameter) and anchorage. The distributed fibers restrain micro- cracking and redistribute accumulated stress caused by applied loads and shrinkage. The sooner the crack is intercepted and its growth is inhibited, the less chance the crack will occur. FAQs of Steel Fiber What is steel fiber reinforced concrete? Fiber reinforced concrete is comprised of hydraulic cements containing fine and course aggregatea and fiber. A super-plasticizer is ofter used to enhance the mix workability. Fiber products are available in a variety of types and sizes. The underlying principle however on all fiber reinforced concrete is to provide discoutinuous reinforcement and effective crack control. How do fiber work? Fibers reinforce in three fimensions throughout the entire concrete matrix. Fiber performance is based on the combination of the tensile strength, aspect ratio(length/diameter)and anchorage. the distributed fibers resrain micro- cracking and redistribute accumulated stress caused by applied loads and shrinkage. The earlier a crack is intercepted and its growth inhibited, the less chace it will have develop. What are the types of steel fibers used in concrete ? 1.Straight 2.hooked 3.Crimped.4.Double duoform 5.ordinary duoform 6.paddied 7.enlarged ends 8.irregular 9.indented. Is there a difference between Micro and Macro Synthetic Fiber? Macro synthetic fibers are intended to carry a load and therefore, can be used to replace traditional reinforcement. Typical applicationss are: slabs on ground, shotcrete, precast and composit metal deck applications. Macro synthetic fibers are also used to eliminate both early and long term cracking. Micro fibers are generally utilized to minimize early age plastic shrinkage cracking and aggregate settlement that can occur within the first 24 hours.
