Since 1880, French physicists P. Curie and J. Curie have discovered the Piezoelectric effect piezo element.The current piezoelectric effect materials can be roughly divided into three categories,it is piezoelectric single crystals, including ferroelectric Piezoelectric discs transducer,non-ferroelec

The ultrasonic transducer is a sound pressure-electrical conversion device that can convert the surface acoustic energy and electrical energy.Since 1917, the French scientist Paul Langevin discovered the inverse piezoelectric effect, it is using quartz crystals as piezoelectric materials.The first p

What are the distance methods for ultrasonic distance transducer?In the ultrasonic distance transducer,distance methods generally have a single-shot dual-receiving type, and it is also a sonic logging method. In terms of composition, there are mainly three sound systems, sound insulators and electro

1.Applications in medical and beauty products.Ultrasonic beauty is generated a high frequency alternating current by generator , which make the piezoelectric chip to generate ultrasonic waves. It mainly uses the mechanism of ultrasonic waves on human skin and superficial tissues. In the medical, the

1.Piezoelectric ceramics, can the voltage be generated to illuminate luminous diode or a flashlamp ?The voltage of piezoelectric ceramics is generated is so small ,which can only reach the micro-ampere level, for the luminous diode or or a flashlamp ,its voltage and current is 2.5V/0.02A, so it can

About piezoelectric ceramics, piezo ceramics generate the DC or AC ? In addition, is it generically a piezoelectric polycrystal?Piezoelectric ceramics produce the direct current, not alternating current. In addition, it belongs to inorganic piezoelectric materials, and this kind material can be divi

1.When is using the piezoelectric ceramic sheet to make a buzzer, why the wire can't be soldered on the piezoelectric ceramic sheet? In addition, capacitance of the piezoelectric ceramic sheet is the same as the ceramic capacitor?The piezoelectric ceramic is used to make the buzzer. If this problem

The equivalent circuit of the complex stator of traveling wave type ultrasonic motor near the resonance frequency is shown . Each parameter of piezoelectric ceramics has the following meaning: the white is the equivalent with static capacitance, which is determined by the dielectric constant of the

Thermocouples of piezoelectric material piezos discs transducer can withstand the large differences in the temperature and heat output. A thin-film thermocouple is consisting of two ITO piezo ceramic by hot electrodes (with different charge carrier concentrations) .which can operate below 1 200 °C;

The high temperature thin film thermometer includes a thin film thermocouple and a resistance temperature detector (RTD). Thin-film thermocouples can be used at 1 000 °C, but the thermocouples drift due to the oxidation of germanium in the thin film. A layer of alumina protecti

Should Fixing piezo disc element Take 3 Steps

PZT piezoelectric element ceramic have conditions of dielectric constant and dielectric loss curve under the the temperature and frequency conversion. The temperature of dielectric constant can be seen. the dielectric constant increases very slowly which the temperature is below 250°C. That is, the
