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 ...

Ultrasonic levitation is by now a familiar trick: one or more ultrasonic transducers create a standing wave, and small objects can be held in the nodes of this standing wave. With a sufficiently large ...

In a recent development, NTT Corporation unveiled the “first” gigahertz ultrasonic circuit that utilizes topological insulator principles, indicating a new era in ultrasonic communication technology.

Piezoelectric transducers are commonin ultrasonic and acoustic-alarm-signaling applications. To getenough acoustic power from a piezoelectrictransducer, you must power thedevice with a frequency at or ...
