Depending on material, these sensors can withstand and work at accelerations of several thousand g. For this reason, they are often used as transducers for sensing pressure-related physical parameters, which includes pressure itself, as well as its related manifestations: acceleration, impact, altitude (air pressure), and vibration. Since they have a crystalline structure, many piezoelectric materials are quite hard and can withstand a great deal of stress without changing their basic characteristics or failing. This spark ignites the gas and initiates a flame (but the current level is so low that there is no danger of shock). (Source: Seiko Epson Corp.)Įven a gas-fired grill can have a piezoelectric element, using a built-in crystal that generates a spark of several hundred volts when the user turns a knob and so squeezes the crystal. Piezo materials are also used as actuators that can be directed to move in precise nanometer-size steps, such as for micromotors in applications ranging from high-end scientific instruments down to autofocusing in mass-market consumer cameras.įigure 1: The piezoelectric effect has a dual nature: a) applying stress on a crystal causes it to generate a voltage while b) applying a voltage to the crystal causes it to deform, both in predictable and repeatable relationships.

In addition, if the piezo driver you are currently using cannot fully meet the needs of your project, or you have not found a suitable piezo driver, feel free to contact us and we will give you professional advice, or customize a piezo driver for your project.These two principles have been adapted to many applications the best-known one is use of quartz as a resonant element in an oscillator circuit. Several high voltage amplifiers launched by Analog Technologies at the same period can also be used as piezo drivers. This piezo driver is a medium voltage amplifier, with 5V DC input voltage, a wide output voltage range of −30V~300V, and an ultra wide operating frequency range of 0.1Hz~20kHz.
#Piezo crystal op amp generator
This piezo driver comes with a built-in signal generator that can generate standard signals such as sine waves, square waves, and triangle waves.

It is flexible and convenient to install in other devices. is enclosed in a metal shell that effectively shields noise interference, with a compact size. The piezo driver APZD300V2A developed and designed by Analog Technologies, Inc. The piezoelectric drive and control devices that have been developed mainly include ultrasonic motors, precision drivers, etc., and have been successfully applied in many fields, such as national defense, biomedicine, and optoelectronics. The piezoelectric crystal features fast response, high precision, and strong anti-interference capability, the driving and control device it involves in is simple in structure and quick in response, and can be used in a wide range of applications. The piezo driver uses the inverse piezoelectric effect to form a mechanical drive or mechanical control. Conversely, the process in which an external electric field forces the piezoelectric crystal to deform is called the inverse piezoelectric effect. The property of the electric potential difference between the two ends of the piezoelectric crystal's polar axis is called piezoelectricity, or piezoelectric effect. Piezoelectric crystal is a non-centrosymmetric crystal, deforming under the mechanical force, which causes the relative displacement of the charged particles, so that positive and negative bound charges are produced on the crystal surface.
