In the medical applications of ultrasonic imaging, sound waves of high frequency are usually employed to produce in-depth cross-sectional images of internal organs. Special multi-element transducers ...

Holodeck, anyone? Researchers at Bristol University are developing a system known as UltraHaptics that uses ultrasonic force fields to project the tactile sensations of objects in midair. Currently ...

There have been important technological advancements made in the nondestructive testing (NDT) industry with total focusing method (TFM) capable inspection devices becoming more common. In terms of ...

Who wouldn’t want an autonomous drone to deliver cans of fizzy drink fresh from the fridge? [Alex Toussaint] did, and in thinking how such a machine might work he embarked on a path that eventually ...

Ultrasonic transducers are incredible, with them you can detect distances, as well as levitate and peer through objects. They can emit and receive ultrasonic soundwaves (typically above 18khz) and ...

To establish ultrasonic testing and derived technique capability (phased array and time of flight diffraction) focusing on the nuclear applications to facilitate service to the nuclear industry and ...

1. Ultrahaptics uses a phased array of ultrasonic speakers fired at precisely selected intervals so the intersection of the waves hit the hand providing a tiny forceful vibration. Ultrahaptics hasn’t ...

Nondestructive testing (NDT) refers to the inspection of materials to ensure their integrity and serviceability without damaging the components in the process. There are various NDT methods used by ...
