But a carbon nanotube coating (shown in clear jacket) replaces the tin-coated copper braid that serves as the outer conductor, ordinarily the heaviest component. Created by researchers at Rice University, the coating was tested by a collaborative group including NIST, which has more than 10 years of expertise in characterizing and measuring nanotu…bes. The coating, only up to 90 microns (millionths of a meter) in thickness, resulted in a total cable mass reduction of 50 percent (useful for lowering the weight of electronics in aerospace vehicles) and handled 10,000 bending cycles without affecting performance. And even though the coating is microscopically thin, the cable transmitted data with a comparable ability to ordinary cables, due to the nanotubes’ favorable electrical properties.

When engineers at the University of California, Berkeley, say they are going to make you sweat, it is all in the name of science. Specifically, it is for a flexible sensor system that can measure metabolites and electrolytes in sweat, calibrate the data based upon skin temperature and sync the results in real time to a smartphone.

While health monitors have exploded onto the consumer electronics scene over the past decade, researchers say this device, reported in the Jan. 28 issue of the journal Nature (“Fully integrated wearable sensor arrays for multiplexed in situ perspiration analysis”), is the first fully integrated electronic system that can provide continuous, non-invasive monitoring of multiple biochemicals in sweat.

The new sensor developed at UC Berkeley can be made into “smart” wristbands or headbands that provide continuous, real-time analysis of the chemicals in sweat.

Another Quantum Breakthrough through ultra- low temp nanoelectronics- Sub-millikelvin nanoelectronic circuits and is another step on the way to develop new quantum technologies including quantum computers and sensors.

The first ever measurement of the temperature of electrons in a nanoelectronic device a few thousandths of a degree above absolute zero was demonstrated in a joint research project performed by Lancaster University, VTT Technical Research Centre of Finland Ltd, and Aivon Ltd.

The team managed to make the electrons in a circuit on a silicon chip colder than had previously been achieved.

Dr Rich Haley, Head of Ultra Low Temperature Physics at Lancaster, said: “This is a notable achievement in that the team has finally broken through the 4 millikelvin barrier, which has been the record in such structures for over 15 years.”

The VR sound barrier; how do we address?

I’m staring at a large iron door in a dimly lit room. “Hey,” a voice says, somewhere on my right. “Hey buddy, you there?” It’s a heavily masked humanoid. He proceeds to tell me that my sensory equipment is down and will need to be fixed. Seconds later, the heavy door groans. A second humanoid leads the way into the spaceship where my suit will be repaired.

Inside a wide room with bright spotlights I notice an orange drilling machine. “OK, before we start, I need to remove the panel from the back of your head,” says the humanoid. I hear the whirring of a drill behind me. I squirm and reflexively raise my shoulders. The buzzing gets louder, making the hair on the nape of my neck stand up.

Then I snapped out of it. I removed the Oculus Rift DK2 strapped on my face and the headphones pressed on my ears and was back on the crowded floors of the Consumer Electronics Show in Vegas. But for a few terrifying seconds, the realistic audio in Fixing Incus, a virtual reality demo built on RealSpace 3D audio engine, had tricked my brain into thinking a machine had pulled nails out from the back of my head.

BMI is an area that will only explode when the first set of successful tests are presented to the public. I suggest investors, technologists, and researchers keep an eye on this one because it’s own impact to the world is truly inmense especially when you realize BMI changes everything in who we view how we process and connect with others, business, our homes, public services, transportation, healthcare, etc.

Implantable brain-machine interfaces (BMI) that will allow their users to control computers with thoughts alone will soon going to be a reality. DARPA has announced its plans to make such wetware. The interface would not be more than two nickels placed one on the other.

These implantable chips as per the DARPA will ‘open the channel between the human brain and modern electronics’. Though DARPA researchers have earlier also made few attempts to come up with a brain-machine interface, previous versions were having limited working.

The wetware is being developed a part of the Neural Engineering System Design (NESD) program. The device would translate the chemical signals in neurons into digital code. Phillip Alvelda, the NESD program manager, said, “Today’s best brain-computer interface systems are like two supercomputers trying to talk to each other using an old 300-baud modem. Imagine what will become possible when we upgrade our tools to really open the channel between the human brain and modern electronics”.

Hot damn, our Ghost in the Shell future is getting closer by the day. DARPA announced on Tuesday that it is interested in developing wetware — implantable brain-machine interfaces (BMI) that will allow their users to control computers with their thoughts. The device, developed as part of the Neural Engineering System Design (NESD) program, would essentially translate the chemical signals in our neurons into digital code. What’s more, DARPA expects this interface to be no larger than two nickels stacked atop one another.

“Today’s best brain-computer interface systems are like two supercomputers trying to talk to each other using an old 300-baud modem,” Phillip Alvelda, the NESD program manager, said in a statement. “Imagine what will become possible when we upgrade our tools to really open the channel between the human brain and modern electronics.”

The advanced research agency hopes the device to make an immediate impact — you know, once it’s actually invented — in the medical field. Since the proposed BMI would connect to as many as a million individual neurons (a few magnitudes more than the 100 or so that current devices can link with), patients suffering from vision or hearing loss would see an unprecedented gain in the fidelity of their assistive devices. Patients who have lost limbs would similarly see a massive boost in the responsiveness and capabilities of their prosthetics.

Interesting article about nanoswitches and how this technology enables the self-assembly of molecules. This actually does help progress many efforts such as molecular memory devices, photovoltaics, gas sensors, light emission, etc. However, I see the potential use in nanobot technology as it relates to future alignment mappings with the brain.

Technical University of Munich (TUM) researchers have simulated a self-assembling molecular nanoswitch in a supercomputer study.

As with other current research in bottom-up self-assembly nanoscale techniques, the goal is to further miniaturize electronic devices, overcoming the physical limits of currently used top-down procedures such as photolithography.
