Piezo Acoustics: Turning Windows into Invisible Speakers and Helping James Bond Keep Secrets

Piezo transducers can turn vibration into electric energy (“the direct piezo effect”) and electric energy into motion (“the inverse piezoelectric effect”). They are used in everyday applications from buzzers to gas igniters and in high-tech markets from medical to semiconductor applications. Typical piezo elements are made of PZT ceramics and the piezoelectric effect responsible for […]

Piezo Transducers, Actuators, and Motor Drive Solutions for Medical Engineering

Medical engineering and life-science disciplines have multi-faceted requirements for motion and positioning equipment: the spectrum spans from ultrasonic transducers to simple low-energy drive components to high-precision positioning systems and ultra-fast actuators for valve and pumping applications. Piezoceramic transducers and motor drives meet these needs and have a long track record of reliability and ruggedness in […]

Accelerated EDM Microstructuring Aided by Electroceramic Transducers

Piezoelectric high-speed motion improves performance of die-sinking EDM in the micron realm. The basic principle of the machining process, now known as electrical discharge machining (EDM), or die sinking, was discovered in the 1940’s by accident, when Russian scientists were trying to prevent the erosion of electrical contacts caused by sparking. Today, EDM is well […]

Piezo Sensors (PZT) vs Fiber Bragg Grating (FBG) Sensors in Structural Health Monitoring

An interesting new research paper on this subject was published recently by the Institute for Construction Science and the Department of Structural Mechanics, Technical University of Madrid, Spain. They compared the two methods on Carbon Fiber Reinforced Polymers (CFRP) composites for repairing and strengthening structures in service. The bottom line was that PZT sensors with […]
