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 ...

A schematic of an ultrasonic receiver that demonstrates how it can be bent and deformed during the process of wirelessly charging the battery of a body-inserted medical device, while maintaining its ...

A recent study from the Korea Institute of Science and Technology (KIST), in partnership with Korea University, and published in the journal, Advanced Materials, has introduced a flexible and ...

Apple is researching the use of ultrasonic ranging to determine how far away iPhones are from each other before opening up lines of communication. Apple's AirDrop is a highly-useful tool for many ...

Bats have been using sonar to navigate and communicate for ages, and now humans can do the same, thanks to lightweight and efficient ultrasound microphones and loudspeakers developed by physicists.

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 ...

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 ...

Researchers at the Georgia Institute of Technology have built a motion and contact sensor ...

The main goal of this application is to design an ultrasonic qualitative distance estimation sensor using Dialog Semiconductor’s SLG47105V. The system is designed using high-voltage (HV) macrocells ...
