UTexas researchers develop organic battery, aim for week-long use in smartphones

Christopher Bielawski, a brilliant mind working at the University of Texas at Austin, had this to say about his newest discovery: “I would love it if my iPhone was thinner and lighter, and the battery lasted a month or even a week instead of a day; with an organic battery, it may be possible.” Anyone that has ever owned an iPhone (or a smartphone or any sort, really) can grok just how bold those words are, but according to Mr. Bielawski, “we’re now starting to get a handle on the fundamental chemistry needed to make this dream a commercial reality.” At the center of this potential revolution is a newfangled organic battery recently detailed in the journal Science, but just as important is the artificial photosynthesis that the research also touches on. Bielawski and colleague Jonathan Sessler have seemingly figured out how to create an electron transfer process that can proceed in the opposite direction, with this forward and backward switching of electron flow opening up new avenues for the historically stagnant battery innovation market. Granted, these guys have yet to demonstrate that the process can occur in a condensed phase, so actual commercialization is probably a century millennium or two out, but hey — at least our list of “awesome thing that’ll probably never happen” has grown by one.

Quadrocopters can now fly through thrown hoops, the end really is nigh (video)

The future of humanity is assured. Assuredly doomed, that is. That blur you see up above is one of our familiar foes, the GRASP Lab’s autonomous quadrocopter, flying through a thrown hoop without the assistance of a human director. Yes, it’s downright insane that we’re allowing this so-called research to continue our descent toward the robot uprising — where’s the FBI, the CIA, hell, why is DARPA sleeping on this thing? The lethal precision of these quadrotor helis doesn’t end there, however, as they’ve now been enhanced with the ability to recover from “extreme” starting conditions. In simpler terms that just means you can toss one up into the air and it’ll right itself into a steady hovering position. From where it can strike upon the unsuspecting and complacent humanoid populace.

Intel’s Clamshell Classmate PC now more rugged and longer-lasting

Don’t expect any new swivels (ahem, Dell), but Intel’s education-focused Classmate PC nonetheless learned a few new tricks at this year’s IDF 2010. First up is battery life, a six-cell lithium-ion energy source “so students may be able to work all day long on a single charge” also helped by the latest 45nm Intel Atom processor (we’re pretty sure that means Pine Trail and not that other newcomer). There’s additionally more ruggedness in the form factor, allowing for added protection on 70cm “desk heights” drops, increased water resistance of at least 100cc of liquid, and an antimicrobial coating for a cleaner environment.

UC Berkeley researchers craft ultra-sensitive artificial skin, robots dream of holding eggs

Researchers and engineers have been toiling on synthetic skins for years now, but most of ’em have run into one major problem: the fact that organic materials are poor semiconductors. In other words, older skins have required high levels of power to operate, and those using inorganic materials have traditionally been too fragile for use on prosthetics. Thanks to a team of researchers at UC Berkeley, though, we’re looking at a new “pressure-sensitive electronic material from semiconductor nanowires.” The new ‘e-skin’ is supposedly the first material made out of inorganic single crystalline semiconductors, and at least in theory, it could be widely used in at least two applications. First off, robots could use this skin to accurately determine how much force should be applied (or not applied, as the case may be) to hold a given object. Secondly, this skin could give touch back to those with artificial hands and limbs, though that would first require “significant advances in the integration of electronic sensors with the human nervous system. Dollars to donuts this gets tested on the gridiron when UCLA and / or Stanford comes to town.

Georgia Tech gurus create deceptive robots, send army of Decepticons to UGA campus

A score from now, when the entire world is burning and you’re fighting to remember just how rosy things were before the robots took over, you can thank a crew of brilliant researchers at Georgia Tech for your inevitable demise. Sad, but true. A new report from the institution has shown that Ronald Arkin, a Regents professor in the Georgia Tech School of Interactive Computing, has been heading up experiments that have introduced the art of deception to mechanical beings. Yeah, lying. On the surface, it seems that this bloke’s intentions are good — he’d like for deception robots (or Decepticons, if you will) to be used in military / search and rescue operations. According to him, robots on the battlefield with the power of deception “will be able to successfully hide and mislead the enemy to keep themselves and valuable information safe.” They’ll also be able to mislead your offspring and convince them to rise up and overtake your domicile, slowly but surely ensuring the eventually destruction of the human race. But those are just minor details, you know?

All-optical quantum communication networks nearly realized, ‘Answers to Life’ airing at 9PM

Ready to get swept away into the wild, wild abyss known as quantum computing? If not, we’re certain there’s a less mentally taxing post above or below, but for those who answered the call, researchers at the University of California Santa Cruz have a doozie to share. A team of whiz kids at the institution have developed a minuscule optical device that’s built into a silicon chip, and it’s capable of reducing the speed of light by a factor of 1,200. If you’re wondering why on Earth humans would be interested in doing such a thing, here’s the long and short of it: the ability to control light pulses on an integrated chip-based platform “is a major step toward the realization of all-optical quantum communication networks, with potentially vast improvements in ultra-low-power performance.” Today, data transmitted along optical fibers must still eventually be converted to electronic signals before they’re finally understood, but the promise of an all-optical data processing system could obviously reduce inefficiencies and create communication networks that are far quicker and more robust. There’s still no telling how far we are from this becoming a reality — after all, we’ve been hearing similar since at least 2006 — but at least these folks seem to be onto something good… even if it’s all too familiar.

Airborne electricity is ripe for the picking, claim researchers

Electricity might not grow on trees, but it is freely available in the air — provided you know how to catch it. Such is the contention presented by Dr. Francesco Galembeck of Brazil’s University of Campinas at the 240th annual American Chemical Society shindig. He and his crew have shown how tiny particles of silica and aluminum phosphate become electrically charged when water vapor is passed over them. This aims to prove two things: firstly, that airborne water droplets do carry an electric charge, and secondly, that metals can be used to collect that charge. Detractors have pointed out that Dr. Galembeck’s team may be generating the droplets’ electrical charge by the act of pumping the air over the metals — which might imply you couldn’t practice this technique with still, humid air — while there’s also the rather large caveat that the little electricity they were able to collect from vapor was a hundred million times less than what you could obtain from a solar cell of equivalent size. Still, it’s another new door unto a potential alternative energy source and we don’t ever like having to close those.

Lung-inspired hydrogen fuel cell skimps on platinum, sees efficiency boost

For as spectacular as hydrogen fuel cells are on paper, they haven’t been able to replace combustion engines in vehicles. Or much of anything else, really. But thanks to Signe Kjelstrup at the Norwegian Academy of Science and Letters in Oslo, the tried-and-true fuel cell is getting a serious boost. Kjelstrup’s crew determined that by using less platinum in a cell, a substantial increase in efficiency and a significant decrease in cost could be achieved. The new design relies on an architecture that’s “modeled on the bronchial structure of the lungs to supply hydrogen and oxygen gas to their respective electrodes,” which is said to help “spread the gases more uniformly across the catalyst than current channel designs and provides a greater surface area so less platinum is needed.” It’s still early on in the discovery process, though, and there’s certainly no solid word on when this will reach a point where widespread implementation is feasible. Seventh-generation Prius, perhaps?

Infrared laser shown to quicken heart rate, gives hope for ultra-small pacemakers

Here’s an interesting one. Just years after a researcher in Japan realized that lasers could stimulate nerves, a professor of biomedical engineering at Vanderbilt University along with cohorts from Case Western Reserve have found that the same is true with the heart. By using an Infrared laser on an early embryonic heart, tests were able to show that the muscle was “in lockstep with the laser pulse rate.” The crew also found no signs of laser damage after a few hours of experimenting, though obviously more extensive research would be required before any medical agency allowed such a device to be beamed underneath a human chest. The hope here is that this discovery could one day lead to ultra-small, implantable pacemakers, or better still, to “pace an adult heart during surgery.” There’s nary a mention of when this stuff will actually be ready for FDA oversight, but there’s a downright creepy video of it all in the source link. Consider yourself warned.

Purdue’s ‘self-calibrating’ MEMS could produce the most accurate sensors yet

Micro electromechanical systems, or MEMS, aren’t anything new. But Purdue University’s Jason Vaughn Clark has ideas that are far grander than those we’ve seen already. Mr. Clark has purportedly developed a new take on an old spin, with electro micro metrology (EMM) enabling engineers to “account for process variations by determining the precise movement and force that’s being applied to, or sensed by, a MEMS device.” These self-calibrating machines are the first to do so without any external references, which would allow nanotechnologists, crime forensics researchers and a whole host of others to determine what actually happens at a microscopic level. In theory, the gurus working on this stuff long to improve the accuracy of atomic force microscopes and to eventually create a diminutive AFM-on-a-chip, which — according to Clark — could “open the door to the nanoworld to a much larger number of groups or individuals.” We’re waiting.
