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 ...

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.

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 ...

Ultrasonography based on traditional bulk piezoelectric transducers has been established as an inexpensive and safe medical imaging modality. By borrowing techniques from the microelectronics industry ...

When we hear the word “Ultrasonic” we often refer it to bats and dolphins communication. Technically, “Ultrasonic” applies to sound that is anything above the frequencies of audible sound, and ...
