Acoustic Waves to Cool Electronics
Acoustic Waves to Cool Electronics

As electronic devices and circuits continue to shrink, cooling them effectively becomes a challenge. Fortunately, Rice University researchers have discovered a way to dissipate heat more efficiently: acoustic waves that travel along nanoscale graphene ribbons. Graphene — a single layer of carbon atoms — is able to transmit thermal energy in waves, of which long acoustic waves perform optimally. Since heat is transported primarily via vibrations, energy can be carried away at the speed of sound, according to physicist Boris Yakobson. While the graphene material conducts heat 10x better than copper or gold, here it would function like a heat conduit, dissipating the wave energy in a gas or liquid.

Custom Sound-proofing and Acoustic
Materials

Merryweather Foam, Inc.

Custom Sound-proofing and Acoustic Materials Looking for a sound-absorption solution? Not sure what you need? You're not alone! Acoustical-absorption products are available in a range of mediums and designs that meet the specifications of engineers working in diverse industries. You may find that many commonly used sound absorbing products cost more than innovative, newcomer solutions.

Feeling Sound via Vibes

Feeling Sound via Vibes The Kinetic Omnidirectional Resonance (KOR) effect is more than a sub-woofer experience and doesn't disturb anyone else. The KOR-fx device transforms audio signals into vibrations that are felt throughout a user's body (see the video). The next-gen version will fool the wearer's brain into thinking that the body is undergoing G-forces, rain, wind, and more.

Ferropaper Makes Mini Speakers

Ferropaper Makes Mini Speakers Take "magnetic nanoparticles" of iron oxide, add a little mineral oil, spread on paper and cover with plastic, and what do you get? Ferropaper is the answer, developed at Purdue University. When subjected to a magnetic field the material moves, making it appropriate for miniature speakers, motors, and robotic applications.

SMAs Reduce Noise, Isolate Vibes

SMAs Reduce Noise, Isolate Vibes Researchers at Japan's Tohoku University discovered an iron-based shape metal alloy (SMA) that recovers when subjected to almost twice the strain allowed by current SMAs — with strength equal to that of high-strength alloys. Such improved performance could lead to components that reduce noise, damp vibrations, and result in smaller, more elastic medical stents.

Smart Cloth Senses

Smart Cloth Senses To provide continuous, real-time monitoring of embankments, levees, roads, and similar earth structures, two industry leaders have announced a collaboration to develop a geotextile monitoring system. The system will use "instrumented" geotextiles with optical fiber (for sensing) woven into the cloth to deliver structural health monitoring, an early warning system plus soil reinforcement, all in one package.

Keeping Connected in the Wild

Keeping Connected in the Wild Thanks to a new smart antenna, emergency responders won't need to endure dropped calls at crucial times while on the move in rugged terrain. Incorporating a chip to aim the transmission beam in just-the-right direction automatically, this "adaptive array" antenna selects the most suitable signal strength and optimizes it. Versus many commercial versions with a 120 degree limited range, this one quickly processes signals over 360 degrees.

Accuracy vs Resolution

Accuracy vs Resolution When it comes to ADCs (analog to digital converters), inadvertently there arises some confusion between accuracy and resolution. As this recent Industrial Control DesignLine article explores, accuracy does not imply resolution and vice versa. Author Mohit Arora, systems engineer at Freescale Semiconductors, explains why this is the case.

Are Lip-reading Cell Phones Next?

Are Lip-reading Cell Phones Next? Shown at the Cebit electronics fair in Germany, a prototype device analyzes electrical signals from the muscles used to speak. Electrodes stuck to a user's face record what's being said — even if the words are just silently "mouthed." Speech synthesis turns the signals into audible speech. One day it may be possible to use your mobile phone silently, without actually speaking.

In Search of Mother Nature's Acoustic Sensors

In Search of Mother Nature's Acoustic Sensors Mimicking Mother Nature is the avenue to many scientific breakthroughs. A case in point is the development of unique acoustic sensors based on insects, such as, how mosquitoes flap their wings. Researchers at the University of Strathclyde in Glasgow are investigating how insects hear so that they can build improved sensors (and actuators) for use in nondestructive material testing, robotic guidance, and ultrasound imaging.

If You Want to Hear, Head Forward, Please

If You Want to Hear, Head Forward, Please Apparently, roller coasters can result in ear injuries. Reaching 120 mph in 4 seconds, one roller-coaster-riding patient was exposed to sound pressure levels equal to a rocket engine when he turned his head. Air pressure then hit his ear drum resulting in major bruising of both the ear canal and ear drum. He recovered. Moral of the story: always face forward.

About This Month's Topic Treacherous Texting on the Road

Despite all of the new laws in place, and the statistics that show how dangerous it is to drive and text at the same time, people are still doing it. Why not talk hands-free instead and be legal?
