Ultrasonic waves propagate in a straight line. The frequency is the higher , the diffraction ability is the weaker, but the stronger the reflection ability. For this reason, ultrasonic sensors can be made using this property of ultrasonic waves. In addition, the propagation speed of ultrasonic waves

With the technological advancement of MEMS, laser technology, high-tech materials, etc., the research and development of ultrasonic sensors is showing a diversified trend. Some application biological materials are to simulate human skin and innovate on the tactile sense of ultrasonic sensors; some M

Ultrasonic transducer sensors developed using the characteristics of ultrasonic waves. Ultrasonic is a mechanical wave with a higher vibration frequency than sound waves. It is generated by the vibration of the transducer chip under the excitation of voltage. It has high frequency, short wavelength,

When is designing a special test instrument for the control unit in the car, the company trusted the force and torque sensors. As one of the components of the tester, the ultrasonic distance transducer has proved its advantages such as high accuracy and automatic quality control, and it meets the re

Ultrasonic distance measurement sensor has a series of advantages, but there are many factors that affect measurement accuracy, so it is difficult to achieve higher accuracy. Based on the principle of ultrasonic distance measurement, temperature, and humidity compensation program of ultrasonic trans

Due to the strong directivity of ultrasonic waves, slow energy consumption, and long distances in the medium, ultrasonic waves are often used for distance measurement. For example, ultrasonic rangefinders and level measuring instruments can be realized by ultrasonic waves. Ultrasonic testing is ofte

Indoor positioning is an application that has been proposed in recent years. How to use ultrasonic transducers for indoor positioning? Take a recent university experiment with the DYA-21-G ultrasonic transducer as an example, here is a brief introduction.

Robot autonomous positioning and navigation of ultrasonic level sensor is simple, but it needs to be based on the combination of map data + algorithm to achieve true automatic automatic navigation; robot navigation can be divided into three parts, including positioning, mapping and motion control. W

Augmented reality / virtual reality (AR / VR) systems are being increasingly used in various fields, such as entertainment, education, healthcare, and other industrial applications. With these technologies, users can simulate complex tasks or surgical operations in a virtual space. Sensing technolog

Smart home appliances are home appliance products formed by introducing microprocessors, ultrasonic sensor technologies, and network communication technologies into home appliances. The intelligentization of home appliances should respond automatically according to the surrounding environment withou

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

In the process of piezoelectric ceramics, if pressure is applied to the piezoelectric crystal piezoelectric transducer, this will directly generate a potential difference, otherwise, when a voltage is applied, mechanical stress will be generated (called the inverse piezoelectric effect). If the pres

The technology of ultrasonically degrading organic pollutants in sewage can be used alone or by ultrasonic cavitation effect, and the ultrasonic degradation technology can be combined with other treatment technologies to degrade and remove organic pollutants. The combined technology has the followin
