The design and modelling of piezoelectric transducers have advanced considerably, merging innovative configurations with robust analytical techniques. Contemporary approaches utilise both equivalent ...

Piezoelectric materials, a type of “smart” material that generates electricity while deforming and vice versa, have been used extensively for many important implantable medical devices such as sensors ...

How does a piezoelectric transducer (actuator) work? Modern Piezo actuators are based on thin piezoceramic layers manufactured in a co-fired process to form a monolithic unit. They are also called ...

A theoretical analysis based on the Johnson noise equation and an established transducer model has revealed a simple mathematical expression for the minimum signal force detectable in air with an open ...

Ultrasound can be used for industrial inspection and automation - the technology is similar to the one know from medical ultrasonic imaging. Piezoelectric ultrasonic transducers also find applications ...

LED drivers that receive their power from a single cell are receiving a great deal of attention. To generate the high voltage for illuminating a white LED from a low-voltage power supply basically ...

An inexpensive acoustic wave transducer developed by NIST mechanical engineers soon may make it easier for researchers to decide if new composite materials or film coatings have the right mechanical ...
