Heart sound is the shock vibration to the chest wall during the heartbeat. The mechanical vibration of heart sounds can be recorded by instruments such as polyvinylidene fluoride (PVDF) piezoelectric ultrasonic transducer , which is called a phonogram. When detecting simulated human heart sounds, th

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 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, a single temperature ultrasonic transducer , humidity compensation scheme

Piezoelectric sensorThe application of piezoelectric sensors for sensing and excitation extends to many areas. This article mainly introduces the induction of some physical intensities, namely acceleration, vibration, oscillation and pressure, which can be considered similar from the perspective of

Piezoelectric ceramics sensors are ultrasonic sensors made by using the piezoelectric effect produced by certain dielectrics. The so-called piezoelectric effect refers to the phenomenon that certain dielectrics undergo deformation (including bending and stretching deformation) due to the polarizatio
