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 ...

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 ...

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 ...

Researchers from Southeast University have developed a compact, dual-band, dual-polarized phased array for B5G/6G ...

A scanner ensures that ultrasonic probes stay properly aligned as they move over the surface of the inspection area. Scanners with motorized actuator arms, suction cups and adjustable, flexible tracks ...

Detecting objects underwater isn’t an easy challenge, especially when things get murky and dark. Radio waves don’t propagate well, so most techniques rely on sound. Sonar is itself farily simple, ...
