Researchers at the Georgia Institute of Technology have devised a passive time-delay component which will make phase-array radars smaller, simpler, more efficient, and less expensive. The thin-film ...
Tsukuba, Japan—Airborne ultrasonic phased arrays focus ultrasonic waves at prescribed locations in space and dynamically steer them, enabling applications such as noncontact tactile feedback, odor ...
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 ...
