In recent years, with the increasingly prominent problems of environmental pollution and climate change, environmental monitoring has become a very important issue. Environmental monitoring is an important means to protect public health and human living environment. However, traditional environmenta

In this spring of 2020, Wuhan Piezohannas Technology Co., Ltd. completed a new challenge-with the accumulation of strong piezoelectric ceramic technology, it successfully converted high-performance piezo disk transducer products into piezoelectric ceramics for mask machines.Wuhan Piezohannas Technol

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

Do you know the amount of electricity on a piezoelectric ceramic chip and how to calculate it?Capacitance and comparison of piezoelectric ceramic chip 1. Can piezoelectric ceramic crystal be called a buzzer?The piezoelectric ceramic crystal can be vibrated and sounded by the AC electric field after

Piezoelectric ceramic is a kind of functional PZT piezoceramics material that can transform mechanical energy and electrical energy. In addition to piezoelectric properties, piezoelectric ceramic transducer also have dielectric properties and elasticity, which are widely used in medical imaging, aco

Sound wave is a kind of longitudinal wave that can be felt by the human ear. Its frequency range is 16Hz~2KHz. When the frequency of sound waves is lower than 16 Hz, it is called infrasound wave, and when it is higher than 2 kHz, it is called ultrasonic wave. Generally, sound waves are having a freq

Compared with traditional two-dimensional ultrasound ultrasound piezoelectric ceramics, three-dimensional ultrasound imaging has an intuitive image display and can be accurate measurement such as volume and area, and the time is required to shorten the diagnosis of doctors.Three-dimensional ultrasou

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

the grains of piezoelectric ceramicsWith the increasing of Mn doping, the grains of piezoelectric ceramics increase first and then decrease, the grain distribution uniformity and grain strength of piezoelectric ceramic transducers are getting worse. Except Mn,it is dominat
