Motion and positioning devices play an integral role in the life-science and medical engineering fields, fulfilling their many different requirements. The spectrum extends from simple low-energy drive ...

Before humans discovered ultrasound for a variety of medical, technical and military applications, nature had perfected it over millions of years for navigation under and above water. Dolphins and ...

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

Throughout the surgical process, the surgeon must have access to a real-time assessment of blood vessels to make evaluations relative to the flow of blood. Piezo transducers are at the heart of ...

Piezo discs have been around since the 1970s, and such cheap (and easy-to-handle) discs are widely used by avid electronic hobbyists and experimenting musicians all over the world. A piezo disk ...

Like all ceramics, piezo ceramics are brittle materials that are well suited to handling compressive loads but are highly sensitive to bending, shear and tensile loads. A number of mechanical ...

Electromagnetic motors and drivers are have been optimized for more than 100 years. They can be found applications from toys to aerospace systems. With all their advantages, there are limitations such ...

Piezoelectric ultrasonic transducers play a critical role in modern sensing and actuation by converting electrical signals into high‐frequency mechanical vibrations and vice versa. Recent advances ...

Piezo elements are electromechanical transducers that convert mechanical forces (pressure, tensile stress or acceleration) into voltages. The inverse piezoelectric effect, precisely the opposite, ...

This design was done to get a sealed keypad for very wet environments (in my particular case, showers for swimming pools). The keypad needed to be able to detect slight pressure on a stainless steel ...

Without mechanical vibrations, a modern car wouldn’t get far down the road – in fact it wouldn’t start. David R Andrews examines the role of sound and ultrasound in fuel injection and parking sensors ...
