This Ultrasonic Sensor Circuit consists of a set of ultrasonic receiver and transmitter which operate at the same frequency. When something moves in the area covered the circuit’s fine balance is ...

Most often ultrasonic transducers are used for distance measurements, and in the DIY world, usually as a way for robots to detect obstacles. But for a weekend project, [Vinod.S] took the ultrasonic ...

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 ...

Ultrasound refers to any audio signal above the range of human hearing. Generally that’s accepted as 20 kHz and up. Unlike electromagnetic signals, ultrasonics are still operating in a medium – ...

Engineers have developed the first fully integrated wearable ultrasound system for deep-tissue monitoring, including for subjects on the go. A team of engineers at the University of California San ...

Engineers at the University of Oxford have built a 256-element helmet-shaped ultrasound transducer that can reach deep brain structures without surgery, selectively shifting neural activity in regions ...
