Nano-Scale Folding for Minute Electronics

Up until now, two-dimensional structures built through X-ray lithography and nano-imprinting have been commonly used as materials for MEMS devices and microprocessors. Potentially though, microprocessors could be made faster and memory devices could function better with the use of 3-D structures. And since the usual techniques can’t create the more complex 3-D forms, further study of the matter is expected.

As of current, MIT scientists are looking into developing the basic principles of what they call “nano-origami,” which is the process of folding materials to form 3-D structures. They serve different purposes in different devices. For example, in capacitors, the more folds there are, the more energy is stored. In memory devices on the other hand, there is possibility for faster information flow. And since everything is in nano-scale, we could be expecting super-fast, super-efficient Lilliputian electronic devices in the future if ever the technology is fully-developed. To get a feel of what nano-origami is, check out the video above of a polymer sheet being folded through currents flowing through wires embedded in the material.

Self-assembling nanoscale discovery could catapult data storage capacity

Ready to have your mind blown? What if 250 DVDs could fit onto a storage module no larger than a quarter? According to research conducted by brilliant geeks at the University of California at Berkeley and the University of Massachusetts Amherst, it’s all within the realm of feasibility. Reportedly, an easily implemented technique “in which nanoscale elements precisely assemble themselves over large surfaces” could soon blow open the doors to significant improvements in data storage capacity. Without getting too Ph.D on you, the process essentially works by taking advantage of just how precise molecules can self-assemble. The end result has researchers achieving “defect-free arrays of nanoscopic elements with feature sizes as small as 3 nanometers, translating into densities of 10 terabits per square inch.” Per square inch, son.

Jacketed hamsters demonstrate movement-powered nanogenerators

Imagine this — one day, with enough steroids, your pet hamster actually could power your home by just running on its wheel. Georgia Tech researchers have discovered ways to “convert even irregular biomechanical energy into electricity,” and it’s demonstrating the finding by showing off jacket-wearing rodents that are game to run. According to the institution’s Zhong Lin Wang, the minuscule nanogenerators “can convert any mechanical disturbance into electrical energy,” which theoretically means that power can be driven by simple, irregular mechanical motion such as the vibration of vocal cords, flapping of a flag or the tapping of fingers. As with most of these university discoveries, there’s no telling how soon this stuff will be pushed out to the commercial realm, but at least they’ve found something to keep the rats busy during the off hours.

Researchers use nano-origami to build tiny 3D devices

MIT researchers are developing a new technique to create simple 3D structures out of nanoscale materials. Called “nano-origami,” the kids are essentially using traditional micro- and nano-fabrication techniques to make 2D objects, at which point they are folded into pre-determined shapes. The folds can be induced by a number of means, including metal deposits (usually chromium), helium ions, and by running electricity through gold wires embedded in the material. While the process is still in its infancy (and all these options only work to a point) a simple 3D nanoscale capacitor has already been built. The current model has only one fold, but the researchers are hoping to increase the number of folds — the more folds, they point out, the better the storage potential. Video after the break.

Artificial trees could function as solar-wind harvester

SolarBotanic is a company which researches and specializes in an emerging tech dubbed biomimicry — which seeks to mimic nature, and use nature-inspired methods to solve human problems. SolarBotanic is focusing on energy production, and, to that end, they’ve developed what they call Energy Harvesting Trees. The trees aren’t “real,” (they’re just modeled on real ones); these are composed of Nanoleafs, which use nanotechnology designed to capture the “sun’s energy in photovoltaic and thermovoltaic cells, then convert the radiation into electricity.” They also have stems and twigs which house nano-piezovoltaic material which act as generators producing electricity from movement or kinetic energy caused by wind or rain. The company has several patents on the technology already, and are currently seeking partners for funding and development. We don’t really have any details about what these fake trees look like — but Thom Yorke’s probably going to write a song about them.

Nanotech research could fit 10 trillion bits of data onto disk the size of a quarter

Two researchers, Ting Xu and Thomas Russell, are in the midst of developing some potentially sweet nanotech that could allow storage of around 10.5 terabits (or 10 trillion bits) of data on a space the size of a quarter. They’re currently working on the technique, which starts with a sliced crystal (sapphire or silicon) sliced at a jagged angle, which is then heated to 2,700 degrees Fahrenheit which causes the crystal to reorganize itself into a sawtooth pattern at three nanometer angles. The crystal is then sprayed with a custom polymer, dried, and treated again with a different solvent, after which the polymer then settles into a hexagonal pattern on the surface of the crystal. Sound complicated? Well, it is, and all the kinks aren’t quite work out, but the technique essentially provides a path to creating a self-assembling disk with far more storage capacity than anything currently available. The current state of the research will be detailed in the upcoming issue of Science magazine. We’ll believe it when we see it, but keep up the good work, guys!

Tattoo-like nanosensor could monitor glucose levels, enhance your cool factor

Make no mistake, there are quite a few sophisticated ways to monitor one’s glucose levels, but we’re pretty certain we’ve never seen an approach as simple and as bodacious as this. Massachusetts-based Draper Laboratories has stumbled upon a new embeddable nanosensor that could, at least in theory, eliminate those painful pricks endured today by so many diabetics. The so-called “injectable nanotech ink” could be inserted under the skin much like a tattoo, though Draper’s Heather Clark notes that it “doesn’t have to be a large, over-the-shoulder kind of tattoo.” In fact, it can be as small as a few millimeters in size, though if it were us, we’d use it as the perfect excuse in order to plaster our backs with Ice Climbers. Testing of the new approach is expected to begin very soon, though that usually means it won’t be ready for humans until at least a few years later. Ah well, plenty of time to dream up the perfect design, right?

Probabilistic logic makes microchip more energy efficient

We’ll be straight up with you — there’s a lot of fancy work going on with this one that laypeople will have a tough time grasping, but the long and short of it is this: a team from Rice University (Krishna Palem pictured) and Nanyang Technological University have created a microchip that “uses 30 times less electricity while running seven times faster than today’s best technology.” Already crying snake oil? Not so fast. By trashing the traditional set of mathematical rules (that’d be Boolean logic) and instead applying probabilistic logic, researchers have figured out how to deliver similar results with a fraction of the energy. The tech is being dubbed PCMOS (probabilistic CMOS), and could eventually end up in embedded systems and even cellphones. In the case of the latter, this type of chip will be able to display streaming video on a minuscule display with more artifacts than usual, but due to the small screen size and the human brain’s ability to piece together nearly-perfect images, the errors involved would be all but forgotten. Meanwhile, your battery bar would still be nearly full. We always heard there was beauty in imperfections — now, at long last, we finally get it.

Rice University rolls out new and improved “nanocar”

Nano-sized letters are one thing, but nothing impresses the nanotechnology community like creepy crawly nanotech, and some researchers from Rice University look to have fully delivered on that point with their latest so-called “nanocar.” At about two nanometers in length, the new nanocar apparently doesn’t represent a drastic reduction in size over the previous incarnation, but it does have the notable advantage of being able to “travel” across surfaces at room temperature (a temperature of 200° Celsius was required before). Interestingly, that breakthrough was actually discovered by accident, and was later able to be confirmed using a mix of time-lapse photography and a new tracking algorithm. As you might have guessed, however, they’re still quite a ways away from being able to actually control the car, although the researchers say using six wheels instead of four could help with that, as could tracks to keep ’em going in one direction.

Demron garments resist radiation without overlooking style

Sure, radiation’s not high on our personal list of threats, but that doesn’t mean it’s not on someone’s, right? Well, to that end, Radiation Shield Technologies has developed a full line of radiation-defeating garments (the thyroid collar being our favorite). In fact, the company has just been awarded a patent for the nanotechnology which they say is the “world’s first protective material designed for all types of chemical, biological, radiological and even nuclear incidents.” The material, called Demron, is a nanopolymeric compound (which they call “liquid metal”) fused between layers of fabric and concocted into gear which is lead-, toxin-, and PVC-free, and is capable of blocking gamma rays, X-rays and other nuclear emissions. The garments are currently used by NASA and various governments across this planet of ours, but they also seem to be commercially available for prices ranging from about $700 up to $6,500 for the nuclear blanket. Citizens of Megaton: rejoice!
