The sound vector transducer is composed of a traditional non-directional sound pressure sensor and a dipole-directed point vibration velocity sensor. It can simultaneously measure the sound pressure at a point in the sound field and several orthogonal components of the particle vibration velocity. T

Piezoelectric materials have an excellent ability to convert mechanical force into electrical charge and vice versa. Piezoelectric ceramics such as lead zirconate titanate, lead magnesium niobate-lead titanate, etc. have been widely used in sensors, actuators, transducers and energy harvesters. Howe

Piezoelectric shock absorption system The piezoelectric damping system can be divided into passive damping and active damping. Passive vibration reduction is to prepare a layer of resistive film on the surface of piezoelectric ceramics. The piezoelectric ceramic converts vibration or noise into elec

The cost of single-layer piezoelectric ceramics is very competitive, and its series resonance point is relatively high, which can exceed the megahertz level, and the vibration strength and output working capacity of the single-layer piezoelectric ceramics at the series resonance point are Quite larg

The piezoelectric ceramic sheet is a key component of the laser positioning system in the working process. When in use, it mainly uses the piezoelectric conversion characteristics of the piezoelectric ceramic. When in use, the length of the laser cavity is adjusted by adjusting the voltage to ensure

Piezoelectric ceramics are often used in the field of biomedicine for their wear resistance, long life and biocompatibility, but it is more than that. It is concluded that piezoelectric ceramics have great prospects in the medical device industry. In recent years, the medical device industry has con

The piezoelectric hydroacoustic transducer is an underwater detection device that can work as both a driver and a sensor. Accurate prediction of its acoustic characteristics in a noisy underwater environment is very important for the design of a robust and durable transducer. The finite element meth
