Nano-3D Manufacturing Technology with Piezo Mechanisms and Laser Lithography

3D printing and additive manufacturing are gaining traction in prototyping and industrial manufacturing of complex parts. Typical 3D printers can produce feature sizes down to a few 10 microns. Significantly higher resolution is available with a new laser lithography system. Here the production of complex three-dimensional micro- and nanostructures is based on photosensitive materials. In […]

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 […]

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 […]

Ultrasonic Piezo Transducers: From Welding to Medical Applications

Standard PZT and Lead-Free Piezo Ceramics Ultrasound has been used in nature for navigation above and under water. Bats and dolphins are but two species who perfected the transmission, reception, and processing over millions of years. Frequencies above 20 kHz – above the hearing range of the human ear – are labelled as ultrasound. What […]

High-Quality Piezo Sound Transducers for the A380 Airbus

Flying may once have been a privilege of the gods but today, traveling by air is taken for granted. The motto is larger, faster, and further but also safety first. Whatever component used in an airplane must be “airworthy” which means reliable, durable, and as light and small as possible. This also applies to acoustic […]
