The Piezoelectric Effect: Technology Generates Functional Benefits

# Anyone not familiar with it might immediately ask: What is the piezoelectric effect? It describes the various processes of electricity generation using a piezoelectric material.   Technically, the piezoelectric effect is described as the linear electromechanical interaction between the mechanical and electrical state in crystalline materials that have no inversion symmetry.   APC International

Piezo Materials for High Power Applications Made in the USA!

Piezoelectric ceramics manufactured from "hard" piezo materials are characterized by having higher mechanical quality factors (Qm) and lower dissipation factors (dielectric losses, tanD) relative to soft PZT's. Ceramic components produced from these "hard" compositions are less susceptible to depolarization from heating under high duty cycles and/or stress. Generally, a lower

After Manufacturing 5: A Brief Introduction to Air Transducers

# In our last several articles we have been delving into the anatomy of single and multiple element transducers as part of our "After Manufacturing" series of articles written to explore the multiple uses for piezoceramics once they are manufactured. Over the next several issues, we will explore some individual transducer

Anatomy of Multiple Element (Stack) Transducers

Last month, we discussed briefly transduction in general and the anatomy of single element transducers and their applications. This month, we will be movin.on to multiple element transducers. Where single element transducers are cost effective, useful for low power applications, operate at the ceramic element's resonance,

After Manufacturing Part 3: Anatomy of a Single Element Transducer

# Transduction, in general terms, means to convert energy from one form to another. In terms of piezoelectric transducers, it means the conversion of electrical to mechanical energy and/or vice-versa. This can take place in a variety of mediums (air, liquid, etc.) using a variety of transducer designs. To simplify our discussion,

After Manufacturing 2: Powering Piezo Devices

# This month we will be discussing how to power piezo devices for transmitting or displacement applications using standard equipment available from APC. Custom power amplifiers and impedance circuits are also available upon request. First things first. When powering a piezo device, it is important to briefly review the frequencies and the
