Ultrasonic

A new chef's knife with sophisticated vibration tech built in promises to cut the effort you put into chopping ingredients in half. It won't buzz loudly, it'll charge wirelessly with an optional accessory, and it'll even prevent foods sticking to it.

Makers, tinkerers, modelers and crafters looking for an edge that smoothly cuts through a range of materials like they're all butter might find the NeoBlade of interest – which is claimed to be the world's most compact wireless ultrasonic cutter.

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.

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.​

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.

The Sonic Decanter promises to improve the quality of your wine in 20 minutes or less by using high frequency sound waves to break down preservatives, such as sulfur dioxide, transform the molecular and chemical structure, and accelerate the aging process.
