Piezoelectric motors can solve critical precision motion problems often better than competing technologies such as linear motors (https://www.pi-usa.us/en/tech-blog ...

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 ...

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 ...

To wirelessly power an implanted neural stimulator, a research team combined materials to synergistically use the magnetorestrictive and piezoelectric effects. Providing power to implanted medical ...

This video shows the ‘Piezoelectric Effect’. The word "piezo" was derived from the Greek word for pressure. In 1880, Jacques and Pierre Curie discovered that pressure produces electrical charges in ...

Development of a theoretical basis for ultrahigh piezoelectricity in ferroelectric materials led to a new material with twice the piezo response of any existing commercial ferroelectric ceramics, ...
