Ultrasonic

Manufacturing could be dramatically changed thanks to two new techniques for joining materials created by scientists in Austria. The two methods create super strong bonds at the pore level, eliminating the need for caustic adhesives.

Scientists have developed a tiny first-of-its-kind imaging sensor designed to build detailed 3D maps of cellular structures inside the body, potentially revealing stiffness and abnormalities that may be indicative of cancer.

If the growing proliferation of smart speakers in our homes makes you a little uneasy, researchers from the University of Chicago might have the answer: a wearable bracelet that jams the microphones in speakers, smartwatches, and smartphones alike.

As any scuba diver knows, communicating while underwater is difficult. Although it's possible to use hand signals, you still have to get other divers' attention so that they see those signals. The Oceans S1 Supersonic dive computer is made to address that problem, using an ultrasonic comms system.

Researchers at the University of Sussex have developed SoundBender, a technology that bends sound waves around obstacles to acoustically levitate objects above them.

The Sonic Soak is designed to act like a tiny, portable washing machine, using sound waves to clean clothes – including your delicates – as well as jewelry, toothbrushes, cutlery, baby items, fruit, veggies and basically whatever else can be thrown into a tub of water with it.

No matter how well you care for your collection, records can be insatiable magnets for surface dust and groove-filling micro particles. A retro-cool machine called the Degritter uses ultrasound to get into the grooves and rejuvenate treasured vinyl.​

Levitation usually only works with particles or tiny objects, but scientists from the University of Bristol have developed a new “acoustic tractor beam” that can trap larger objects, possibly paving the way for contactless production lines or even human levitation.

​When it comes to obliterating blood clots, doctors have at least two options: intravascular ultrasound tools or tiny diamond-tipped drills. Unfortunately, both approaches have drawbacks. A new ultrasound "drill," however, may strike the perfect balance between the two.

Last year, ORNL scientists revealed they were working on ultrasonic clothes drying technology. At the time, they said they planned to implement the technology in a press dryer and a clothes dryer drum. A new video shows they've been true to their word.

Physicists from the UC Berkeley, have used graphene to create ultra-thin, lightweight microphones and speakers that enable high-quality, ultrasonic two-way communication and a frequency response that is claimed to be flat across the entire audible spectrum.

To help avoid delicates shrinking to doll size or ending up a gray, shredded mess, Swiss engineering lab MPI Ultrasonics has come up with Dolfi, a pocket-sized device that makes laundering hand-washables a hands-free job.
