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 ...

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 ...

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 ...

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 ...

The increasing miniaturization and sophistication of electronic products, ranging from consumer media devices to medical diagnostic tools to defense-related sonar applications, presents a bounty of ...

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 ...

This unique dual harvesting arrangement, which simultaneously harvests energy from magnetic fields and ultrasound sources, can provide more power than either one alone—at no cost. Why dual-source ...

Will piezoelectric-based speakers replace traditional speakers over the coming years in space-constrained devices? We have definitely seen the use of piezo transducers in e.g. high-end televisions ...
