Ultrasound

A test subject receives ultrasonic hand stimulation, that reportedly causes them to experi...

We've already seen interactive technologies that create smells or tactile sensations on command. Now, however, British scientists have developed a system that they claim can be used to make users experience specific emotions – and it does so without even touching the person.  Read More

Researchers at the University of Queensland have claimed an effective new, non-invasive me...

Alzheimer's disease is a chronic neurodegenerative disease that most often begins in people over 65 years of age. Usually it starts slowly and continues to worsen over time until the sufferer succumbs to an increasing loss of memory, bodily functions and, eventually, death. Research has shown that there is an association with Alzheimer's and the accumulation of plaques that affect the neuronal connections in the brain. Now researchers at the University of Queensland have discovered a new way to remove these toxic plaques using a non-invasive form of ultrasound therapy.  Read More

Magnetic resonance (MR) imaging-guided ultrasound, a technology that involves highly-targeted ultrasound beams and monitoring their effects through imaging, has shown to help treat symptoms of Alzheimer’s disease in mice. The treatment was found to improve brain performance in the animals and has the researchers hopeful that the technique may prove effective in improving cognitive behavior in humans.  Read More

The University of São Paulo's non-resonant acoustic levitator

Acoustic levitators are already pretty intriguing devices, in that they use opposing sound waves to suspend small objects in mid-air. Now, however, scientists from Brazil's University of São Paulo have created what they claim is a better acoustic levitator. It's less fussy about the exact orientation of its components, making it more feasible for use in practical applications.  Read More

Researchers have used projected ultrasound to create floating 3D shapes that can be seen a...

Haptic feedback has become a common feature of recent technology, but such systems usually rely on stimulation of parts of the user’s body via direct mechanical or acoustic vibration. A new technique being developed by researchers at the University of Bristol promises to change all of this by using projected ultrasound to directly create floating, 3D shapes that can be seen and felt in mid-air.  Read More

When it comes to robots that perform internal inspections of water pipes, virtually all of them move along on rubber tires or treads. As that rubber grips against the inside of the pipe, however, it dislodges rust particles that ultimately end up coming out of peoples' taps. In an effort to address that problem, the European Union TRACT project is developing a propeller-driven inspection robot that keeps the pipe-touching to a minimum.  Read More

Metamaterials negate the properties of the so-called aberrating layers, allowing ultrasoun...

Score another point for metamaterials. Researchers at North Carolina State University have designed complementary metamaterials that will aid medical professionals and engineers in diagnosing problems under the skin. These metamaterials are structured to account for so-called "aberrating layers" that block or distort the acoustic waves used in ultrasounds, making it possible to now conduct ultrasounds of a person's head or an airplane's wing – among other things.  Read More

The HaptoMime uses ultrasound to make users feel like they're touching a display that isn'...

Touchscreen interfaces may make our lives easier, but the things do tend to get smeared with finger oil and whatnot, plus they're notorious for spreading germs. That's why a team of researchers at the University of Tokyo, led by assistant professor Yasuaki Monnai, have developed the HaptoMime. It's an ATM-like interface that lets the user feel like they're touching a glass screen, when in fact they're touching nothing at all.  Read More

The new Soundlazer Snap from Richard Ahberkern

The creator of the pocket-sized Soundlazer directional speaker has revealed a more cost effective way for sonic scientists to get up to all sorts of narrow beam larks with friends. The new Snap does away with the funky red aluminum outer casing and ditches the complex digital signal processing in favor of a simple snap-together frame, board and ultrasonic transducers.  Read More

The virtual breast created at MTU could help improve cancer detection using ultrasound ela...

With the aim of improving clinicians' interpreting of ultrasound elstography images for breast cancer diagnosis, researchers at Michigan Technological University (MTU) have created a fake breast – that's silicon fake, not silicone fake.  Read More
