A solid-state ionic bilayer generates stable electricity for over 60 hours through spontaneous ion migration alone, ...

Abstract: It is a long-lasting issue that process variations, such as residual stress and poor dimension definition, deteriorate resonant frequency control of a piezoelectric micromachined ultrasonic ...

Abstract: In this brief, the motion control of piezoelectric positioning stages with unknown parameters is focused on, and an adaptive backstepping fast terminal sliding mode control based on the ...

Scientists unveil a new class of lead-free materials that could change how everyday devices generate power from motion. And they achieved it using a soft, hybrid structure made from an unlikely ...

Researchers have developed a piezoelectric material that is durable and sensitive to movement, an advance that could be integrated into sensors, wearable electronics, and self-powered devices. A ...
