Principle of piezoelectric ceramic transformerPiezoelectric ceramic transformer is a new type of chip device that realizes low voltage input and high voltage output through the secondary energy conversion of electrical energy --- mechanical energy --- electrical energy. I

Sonar transducer and underwater acoustic transducers are two kinds of detection devices that are often heard. Many people think that these are a kind of ultrasonic sensor. What is the difference between these two transducers?The sonar transducer directly detects and recognizes the objects in the und

I. IntroductionIn the process of real-time obstacle avoidance and path planning for autonomous mobile robots, the robot must rely on the acquisition of external environmental information, sense the presence of obstacles, and measure the distance of obstacles. At present, robot obstacle avoidance and

Detecting the position of the piston in the cylinder is essential for accurately monitoring and controlling various machines and systems-from pneumatic control on the production line to hydraulic cylinders on excavators, to dumping parts on trucks. Traditional solutions usually modify the cylinder i

Detect, collect and locate target objects through ultrasonic transducerIn the automated systems, there are many ways to detect, collect and locate target objects. You can use magnetic fields, dielectric constants (properties of matter), light and sound waves to detect metals, non-metals, magnets, so

Ultrasonic wind speed transducer and wind direction are one of the important meteorological elements. Especially in the construction of navigation and emergency vehicle-mounted automatic weather stations, mobile wind speed and wind direction measurement systems are required. In addition, environment

In the special piezo ceramic industry, there are also some "flavoring agents". Although the amount added in the piezo ceramic formula is very small, it has a very important role in improving the processing performance of special piezo ceramics and improving the performance of special ceramic product

Barium titanate is the basic raw material of electronicpiezoceramics and the pillar of the electronic ceramics industry. Barium titanate has high dielectric constant and low dielectric loss characteristics as well as excellent ferroelectric, piezoelectric, withstand voltage and insulation properties

Ultrasonic welding transducer is an energy conversion device, and its performance description and evaluation require many parameters.The characteristic parameters of the transducers include resonance frequency, frequency bandwidth, electromechanical coupling coefficient, electroacoustic efficiency,

After 76 days of "closing the city",Finally WuHanis unblocked on April 8th. With the efforts of the whole people, it lasted more than two months. The domestic epidemic situation can be said to have been "controlled." The overseas epidemic situation is still severe (the number of newly diagnosed over

Application and characteristics of focused ultrasound:The low-frequency concave-convex piezoelectric ceramic transducer has been theoretically and finite-element-analyzed. The transducer has the characteristics of low resonance frequency, small impedance, high emission voltage response, small 360-de

NDT is the abbreviation of Non-destructive Testing.NDT refers to a test method that does not damage or affect the future performance or use of materials or workpieces.By using NDT, defects in the interior and surface of materials or workpieces can be found, geometric characteristics and dimensions o

Touch screen (also known as "touch screen", "touch panel") is an inductive liquid crystal display device that can receive input signals such as contacts. When a graphic button on the screen is touched, the The haptic feedback system can drive various connected devices according to a pre-programmed p

Abstract: Summarize the defects and possible non-destructive testing methods used in the manufacture and use of automobiles and railway tankers, including radiation, ultrasound, magnetic particles, penetration, magnetic leakage, acoustic emission, and magnetic memory testing, etc., and introduce eac
