UT RESEARCHERS DEVELOP ®EVOLUTIONARY CIRCUITS

Researchers of the MESA+ Institute for Nanotechnology and the CTIT Institute for ICT Research at the University of Twente in The Netherlands have demonstrated working electronic circuits that have been produced in a radically new way, using methods that resemble Darwinian evolution. The size of these circuits is comparable to the size of their conventional counterparts, but they are much closer to natural networks like the human brain. The findings promise a new generation of powerful, energy-efficient electronics, and have been published in the leading British journal Nature Nanotechnology.

One of the greatest successes of the 20th century has been the development of digital computers. During the last decades these computers have become more and more powerful by integrating ever smaller components on silicon chips. However, it is becoming increasingly hard and extremely expensive to continue this miniaturisation. Current transistors consist of only a handful of atoms. It is a major challenge to produce chips in which the millions of transistors have the same characteristics, and thus to make the chips operate properly. Another drawback is that their energy consumption is reaching unacceptable levels. It is obvious that one has to look for alternative directions, and it is interesting to see what we can learn from nature. Natural evolution has led to powerful ‘computers’ like the human brain, which can solve complex problems in an energy-efficient way. Nature exploits complex networks that can execute many tasks in parallel.

Another major leap forward in Quantum; researchers have been able to transport heat consistently ten thousand times further than ever before. This will enable Quantum technology to be leveraged in across multiple areas of manufacturing (clothing, etc.), energy, and electronics due to its heat conductive properties.

Heat conduction is a fundamental physical phenomenon utilized, for example, in clothing, housing, car industry, and electronics. Thus our day-to-day life is inevitably affected by major shocks in this field. The research group, led by quantum physicist Mikko Möttönen has now made one of these groundbreaking discoveries. This new invention revolutionizes quantum-limited heat conduction which means as efficient heat transport as possible from point A to point B. This is great news especially for the developers of quantum computers.

Apple’s quietly building a small army of virtual reality developers, and has been working on a headset for several months, but it’s been typically vague about its plans with the public. And on Friday, company representatives confirmed it’s made yet another another acquisition.

“Apple buys smaller technology companies from time to time, and we generally do not discuss our purpose or plans,” Apple told Tim Bradshaw of the Financial Times, confirming its buy of Flyby Media, a company that “is dedicated to building new technology that can elevate, rather than replace, our real-world experiences.”

Flyby Media specializes in SLAM — simultaneous localization and mapping — a technology that uses a camera and sensors to track an object’s position in real time, something needed for augmented and virtual reality. Flyby also worked with Google on Project Tango, which “gives a mobile device the ability to navigate the physical world similar to how we do as humans.”

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.

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.
