Researchers have devised a method that could power electronic devices from any source of movement

One of the biggest issues with keeping batteries in a myriad of devices charged is how to generate the electricity needed to charge them. Work around the world is being done on new methods of generating electricity from wind power to harnessing the power of ocean waves.

A group of researchers from the Georgia Institute of Technology has announced a new breakthrough that could one day provide power to cell phones and other electronics devices by generating electricity from blood flow in the body.

The researchers have devised a method that allows the generation of energy by converting low-frequency vibrations from body movement, heartbeat, blood flow, and the wind into electricity. The discovery uses zinc oxide nanowires that generate electricity when subjected to mechanical stress.

The nanowires are very small at about 1/5,000th of the diameter of a human hair and about 1/25th of the length of a human hair. According to researcher Zhong Lin Wang from the Georgia Institute of Technology, the nanowires can be grown on materials like metals, ceramics, polymers, and clothing.

Wang told MSNBC, "His research will have a major impact on defense technology, environmental monitoring, biomedical sciences and even personal electronics."

Wang sees the technology being integrated into military clothing where electricity can be generated and used to power devices in the field such as radios and night vision goggles. The nanowires could also be used to power biosensors implanted under the skin.

Wang said, "Quite simply, this technology can be used to generate energy under any circumstances as long as there is movement." Wang and his team's research was funded by DARPA.

A group of students from MIT also recently announced the development of a shock absorber for vehicles that uses the up and down motion when driving to generate electricity. Shock absorbers of this type could be used in future hybrid or electric vehicles to increase the electric powered run time.

Its a good show, but the back story makes very little sense to me. I mean...why did the Cylons wait 40 years to attack? Why even come back? Why do they care? They have a planet of their own, leave us alone!

That's how Cylons roll. Never forgive never forget. It's in their memory banks. 40 years was to make sure our gaurd was down.

You're confused by the idea that the Cylons attacked on the very day that the last military ship capable of fighting them was schedule to be decommisioned? If you live forever, what's a 40 year wait to garauntee your revenge?

awww you guys are slipping, you need to watch the new season's episodes. They are all already mostly aired. I'm not going to tell you what happens and ruin it for everybody, BUT suffice it to say that many of the questions you posed will be answered...

Where do you live? Here in America all the episodes have aired already. Someone already mentioned a spoiler in this thread too. I think this is still a valid debate regardless of the ending. Seems to me it's all about a thing called revenge.

Wrong. There were many newer and active Battlestars more capable than Galactica, but they were all wiped out in the attack except Pegasus.

No, you're wrong.

Against the Cylons, "more capable" = "not networked". Galactica was the only remaining non-networked battlestar in the fleet, because Adama and Tigh wouldn't give up that particular discipline. The newer, active Battlestars were in fact less capable against a Cylon threat, and were comprised and destroyed almost immediately as a result.

It WAS a good show in season 1. When humans were the good guys and Cylon's were bad and conflicts actually mattered.

Every season since has been a travesty. Leading to the ultimate, and boringly predictable conclusion that..

And we are all cylons anyway.

Yeah... No winner, no looser. Let's all hold hands and sing hippie songs and live happily ever after in forgiveness. PUKE !

The final season was the biggest pile of crap and I can't believe I made myself watch it. I'll never forgive them for what they did to Adama. They took a character with unwavering resolve, guts, and courage and turned him into a compromising unstable shell of a man addicted to drink and pills. The one character in a cast full of traitors, skin jobs, and mutineering murderers that I could still respect.. and they ruined him.

I spit on everyone who had a hand in the series after Season 1.

I'm with you. The existential baloney they came up with might have pleased the critics, and it was actually pretty highbrow sci-fi, but it wasn't all that entertaining.

I think they changed the storyline so they could cancel their expensive render-time contracts and stop having space battles. The special effects went out the window after the Pegasus went out in a blaze of glory, and all we had left was angels and prophecies. Bah!

OK, it was different. They should have at least had some more hand-to-hand fighting with Centurions, etc. rather than the little flashes we got at the end of the series. Even the grand finale was disappointing. Actually, my wife liked the series better than I did by the end - and that is just plain wrong, for sci-fi.

I think you guys are confused. They aren't all cylons. Some were hybrids. There were only 15 pure cylon-humans.

The premise was not about revenge.

The reason cylons didn't attack until 40 years later was already mentioned.

I think you guys need to watch the series again.

Length of a human hair?

The nanowires are very small at about 1/5,000th of the diameter of a human hair and about 1/25th of the length of a human hair.

Diameter of a human hair... a common comparison.

Length of a human hair...? Huh? Who's hair?

The source article has it correct. The nanowire's length is equal to 1/25th the diameter of a human hair.

why do the titles of all these articles suck? all you are doing is writing a brief summary of another news article hosted elsewhere. an msnbc article no less with obviously the same knack for outlandish titles. why don't you just say such and such technology developed, in this case nanopiezoelectronics which are not breaking news. this is basically just mentioning a couple likely applications while promising something that hasn't happened yet. saying that we have a method of harvesting energy from bloodflow is incredibly vague, while nanopiezoelectronics is quite clear. it's the same crap with the graphene clock multiplier. your article titles just suck.

why don't you post links to or so that you get your stories from the horses mouth instead of its ass?

I too was surprised to not see the word piezoelectric anywhere in the article (or title...). Since you check every day you probably know this, but DailyTech is often better at getting the Daily part right than the Tech.

The site is still worth checking, but now that I have stacks of Science and Nature to read at lunch every day its not quite as attractive as it once was.

The energy isn't free.
By CZroe on 3/29/2009 2:21:00 AM , Rating: 3
The energy isn't free; it comes from the heart. The heart puts energy into the blood to make it move. You take that energy out and it has to compensate by working harder to put more in. Tapping it thusly would either slow circulation or overwork your heart due to more resistance in the blood flow. The taken energy directly translates into circulatory resistance.

Now, some of the other ideas may work better, but this one is just... wacky. At least it is for anything that isn't about as demanding as a calculator, and who would risk it for such a small amount of power? What if the filaments break off and reach the brain?

And isn't DARPA some innitiative lost on an island somewhere?

If they could find a way to safely attach one to the heart, that's damn near infinite power. It would be nice to know just how much power this would generate tho...

Now that's a good use for the humans! I knew it, humans are not totally worthless. I guess that's how they used them to generate energy in the Matrix!
