Piezoelectric Transducers: Advantages Piezoelectric transducers are transducers that can convert any form of pressure or mechanical stress into electrical energy. To begin this discussion of piezo transducers, we must first understand the components of such a…
Piezoelectric Stack Actuators Piezo elements are materials that can produce an electric charge when deformed. On the other hand, these elements conversely expand or contract when an electric charge is applied, generating force and linear…
What are Multilayer Piezoelectric Actuators? Multilayer piezoelectric actuators, also known as stack actuators, are exactly what they sound like – it’s a stack of multiple thin piezoelectric actuators. Due to several properties of piezoelectric crystals,…
In the last decade, piezoelectric bimorph applications worldwide have expanded dramatically. A new class of miniature, highly-specialized instruments, alarms and sound production devices, requiring very low power consumption, are needed in countless emerging applications. Piezoelectric…
What are Piezoelectric Bimorphs? Piezoelectric bimorphs, as the name suggests, involve two separate pieces of piezoelectric ceramic put together in such a way that when a voltage is applied, the piece bends (only actuators do…
What are Piezoelectric Transducers? Transducers are devices that convert one form of energy into another and can be categorized into many different kinds. Sensors and actuators are both kinds of transducers, with categorization being determined…
The Growing Piezoelectric Industry The piezoelectric effect isn’t something most are familiar with despite its prevalence in technology. Ask someone how their printer works, and most would fail to provide an answer, and if they…
What are Piezoelectric Sensors? Piezoelectric sensors are transducers that convert environmental conditions into readable and usable electrical signals. There are two types: active and passive. The former sends ultrasonic signals and waits for a response,…
Interesting Information on a New Class of Piezoelectric Actuators and Assemblies from Piezo Direct Many companies who are thinking about integrating piezoelectric components into future products often ask many questions regarding how piezoelectric actuators function…
The possibilities are endless for the future of piezo technology. Just last month, NASA announced a collaboration with Georgia Tech Research Institute to build a 40,000 square foot outdoor footpath using piezoelectricity. This project will…
