Ultrasonic and piezoelectric actuators have emerged as pivotal components in precision engineering, where the conversion of electrical energy into minute mechanical motion is essential for ...

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 understanding and treatment of brain function and neurological disorders took a step forward with findings from a study of piezoelectric nanoparticles stimulated by low-intensity pulsed ultrasound ...

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 ...

Inserting an electronically-sensitive nanoparticle enabled Boston College researchers to non-invasively trigger macrophages, which are cells central to the body’s immune response Chestnut Hill, Mass ...

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 ...

BBB opening and deep brain stimulation Schematic showing how systemically administered piezoelectric nanoparticles release NO locally in response to ultrasound and accumulate in the brain via BBB ...

Piezoelectric effect is when certain solid material is compressed under mechanical stress, and it develops a voltage potential by accumulating electrical charges. French physicists Jacques and Pierre ...
