Reality from fiction : Fabric that deflects bullets (Indian again)

[tweetmeme] Remember The Matrix? When Neo asks Morpheus if he was trying to tell him that he could dodge bullets and Morpheus replies “No Neo. I’m trying to tell you that when you’re ready, you won’t have to.”


If engineers at the Centre for Advanced Materials Technology, University of Sydney, have their way, then soon the cops of the world could all be attempting a Matrix scene. If not stop the bullets in mid-air, they can surely bounce them off their bodies.

Till today, bulletproof gear that cops across the world use is made up of multiple layers of Kevlar, Twaron, Spectra (Thanks Guybrush) or Dyneema fibers which offer blunt resistance to the brutal force of a bullet. They tried to stop bullets from penetrating by spreading the bullet’s force. But the people who use them can still be left with severe bruising or, worse, damage to critical organs.

The new material, however, not only stops bullets but deflects them, rather than absorbing their force. The study by engineers at the Centre for Advanced Materials Technology, University of Sydney, is published in the Institute of Physics’ journal Nanotechnology. The elasticity of carbon nanotubes means that this so called “blunt force trauma” may be avoided, say Prof Liangchi Zhang and Dr Kausala Mylvaganam. The Indian and Chinese duo who have help fortify the argument that Innovation does not happen only in the west.

The teams’ testing was done on Carbon nanotubes in the dimensions of 0.7 nanometers in thickness & 7.5 nanometers in length. Bullets made out of Diamond were fired at 1000 to 3500 meters per second at the target material and the fabric successfully bounced the bullets off of its surface. Now if diamond bullets could not make it through, then I doubt if anything else will. Engineers claim that 6 layers of such yarn, which would be about 600 nanometers thick, would be sufficient to design a fabric for practical purposes.

To say that this technology is amazing would be a gross understatement. It could prove invaluable in fighting terror across the planet.Just hope the Bad guys are not wearing the same.

Nokia again with Self Charging Phones

[tweetmeme] A few days back I wrote about Nokia Research center working on a prototype technology that would allow cell phones to charge using the radio airwaves that so many radio  transmitters like wifi, radio and GSM use.

Nokia is a genuine game player when it comes to modernizing mobile communication. When just everything is being designed to run on alternative form of energy, it’s fitting that even the mobile phones are set on route. For this, the cellphone maker has filed a US patent application for a phone that can work continuously without requiring to be plugged into a wall socket for a recharge.

The patent is for a self charging phone, which would harvest energy from its owner’s motion. This will be possible courtesy built-in piezoelectric generators that would be placed to help generate electricity from kinetic energy. The phone will have all the heavier components, such as the radio transmitter circuit and battery, supported on a sturdy frame. The frame will be able to move along two sets of rails. Piezoelectric crystals sit on the end of each rail and generate a current whenever the cellphone is moved. So as the user walks, or otherwise moves the phone, electricity is generated to recharge the onboard battery.

A lot of people actually are these days talking about how Nokia is loosing its grip on the cellphone market and the high end innovation is no longer coming from Nokia. However, with technologies like these there seems to be a ray of hope for Nokia to walk back into the hearts of the skeptics. The fact that the iPhone and other high end phones still cost more than they do in the United States in most of the world will definitely give Nokia the time they need. What do you think ?

Google visualized (facts and figures)

[tweetmeme] Info graphics are one of my favorite topics in the world, Google ranks as the most favorite. So when someone comes upon the info graphic of Google, I had to write about it.

What if tattoos were changeable … ???

I mentioned how I am finding it difficult to decide on a tattoo, and in my quest to find a great design had led to dead ends so far. However, the quest is still on.

One of the biggest fears is the fact that, we need to know what it looks like, I mean it might look good on paper but in reality it might not really look that good. So well we can turn to technology then, I mean its there to make our lives easier. Fortunately, computer graphics artist Loic Zimmermann has developed a program that will allow users to get a look at what a complex design might look like on a 3D figure. If this technology catches on, the possibilities for pushing the art form are obvious. What if you can check on the tattoo and what it would look like before trying it on ? Well here is the answer to that question.

The biggest fear in getting a tattoo is the it might sound like a good idea at that time, but then later it might not really represent you as a person. Technology is the way to go, Phillips the guys who gave us nearly every consumer electronics device (prototypes at least) have a solution to this as well. A prototype of the Skin : Tattoo from Phillips is here. Check out the video below.

Philips Design examined the growing trend of extreme body adornment like tattoos, piercing, implants and scarring. The Electronics Tattoo film expresses the visual power of sensitive technology applied to the human body. The film subtly leads the viewer through the simultaneous emotional and aesthetic transformations between two lovers. Check out the Phillips Design Webpage here.

Another solution is detailed at New Scientist, here is the article below :

If you are planning to express your undying love for someone with a tattoo, you might want to wait a little while before going under the needle. New inks that are safer to use, and far easier to remove should you have a change of heart, are set to be launched next year.

The US Food and Drug Administration has no standards for the safety of dyes used in body art. Carbon black, metal salts and other compounds more commonly used in printing or car paint are among those used. Heavy metals and other toxic chemicals in these pigments can seep into the lymph system, says Martin Schmieg, president of the company Freedom-2 in Philadelphia, which is planning to introduce a range of dyes that have already been approved by the FDA for use in cosmetics, food, drugs and medical devices.

Such dyes have not been used in tattoos before as they are readily absorbed by the body. To get round this problem, Rox Anderson at the Massachusetts General Hospital in Boston has developed a way to encapsulate the dyes in protective polymer beads just 1 to 3 micrometres in diameter. This is small enough to allow them to be injected into the skin and absorbed by skin cells to form a tattoo.

The pigment can be removed with a single laser treatment. This splits the beads open, dumping the dye into cells where it is absorbed. The tattoo then quickly fades away, in stark contrast to standard tattoo pigments. Applying a series of up to 10 laser treatments can usually bleach them, but only half of tattoos can be completely removed.

A brief History of everything in 3 Mins and 12 Secs

[tweetmeme] There are a few times when you are left speechless, this is one of them. I was completely left speechless how a 17 year old boy can explain a brief history of nearly everything within 3 Minutes and 12 Seconds. Check out the video below.

Honestly nothing else to say.
