Building Electronics Out Of ‘Paper And Fabrics’

June 10, 2011 by Raj Agrawal Leave a Comment

Nano technology will play the lead. Researchers at the North Carolina State University are working on ways to apply nano-coatings to cheap, flexible materials like textiles which have conventionally been applied and confined to inorganic materials like silicon, used for the construction of microelectronics.

It is intended to improve the cost efficiency and flexibility of the electronic devices, well suited for application in health monitoring mechanisms. This was justified by the statements of Dr. Jesse Jur, assistant professor of textile engineering, chemistry and science, and lead author of a paper describing the research.

We’re not expecting to make complex transistors with cotton, but there are simple electronic devices that could benefit by using the lightweight flexibility that some textile materials provide,” Jur explains.

Research like this has potential health and monitoring applications since we could potentially create a uniform with cloth sensors embedded in the actual material that could track heart rate, body temperature, movement and more in real time. To do this now, you would need to stick a bunch of wires throughout the fabric – which would make it bulky and uncomfortable.

The research has been recently published in the Advanced Functional Materials issue and is funded by the Department of energy and the Nonwovens Cooperative Research Center.

Flashing Electronic Ink Displays On “Clothes”

June 7, 2011 by Raj Agrawal 1 Comment

It won’t be long enough when we begin seeing T-shirt apparel or even tyvex cloths enclosing our postal envelopes, being fully embedded with animated messages and icons. This upcoming technology is pushing the capabilities of the existing electronic inks to a bright new level.

We’ve witnessed the invasion of Electronic readers packed in super thin plastic case and even proper e-papers that can easily store and display written content at our convenience, consider Amazon’s Kindle which is powered by E-Ink’s ‘virtual ink’ technology.

Now, this concept of virtual ink has been taken a step ahead to place them onto cloths, and we know that cloths can easily be crumpled and folded owing to it’s physical nature. So let’s say, sometime in the future, we may actually see status updates from Twitter and Facebook on our apparel, or worse, advertisements! As pointed out by FastCompany.

Watch the video demonstrations of how the display works when embedded onto cloths, and yes, it works perfectly even with the crumpling and folding efforts!

These screens are powered by SURF which defines a Segmented, Ultra-thin, Rugged and Flexible display. An interesting aspect of this futuristic display is that the screens are easily viewable in open light as opposed to many flat display ones, allowing the content to be easily readable even in bright sunlight. This is possible because of a reason that E-Ink products display reflected light just as a regular paper does.

E-Ink is ready with this technology and could commercialize their electronic ink displays on such cloths anytime soon. They just need an interested party who may fund the production overheads.

Sling Media’s Slingbox, Now In India – Price, Specs And Features

April 16, 2011 by Raj Agrawal Leave a Comment

It’s “the future of remote television”, meant to entertain on the go, for people willing to access their own home television network anywhere in the world without paying extra subscription fees.

Sling Media has announced the availability of Slingbox in India, with which the users can access their home television on their portable/ home theater screens anywhere in the world. It’s a great system for people seeking entertainment “from” their home television channels, on the go.

With an active internet connection, Slingbox (compatible with Windows and Mac) allows the users to watch television from standard to high definition video/ audio quality, depending on the Slingbox type and the internet upload/ download rate. A Slingbox variant, PRO HD version allows users to watch home television remotely up to 1080i resolution. Ofcourse, the source input must provide with a 1080i video stream and you need a equivalently good bandwidth

With all the beckoning claims and for who aren’t sure about what Slingbox does, allow me to explain.

Lets consider a television input. The Slingbox device is connected to the “main source” of the television or the television itself. The user at the other end of the world controls the home television with a virtual remote control and the video stream is quickly available on the output device.

Mind that the Slingboxes all around the world have a USB 2.0 port which do not function. The speakers at the Sling Media press event (held in Mumbai) mentioned the reason behind the non-functionality of the USB ports is intentional and for the convince of the users. Earlier, the USB ports were intended for firmware upgrades and many users found it inconvenient, so they planned to automate the upgrading process via the internet and block the USB ports for the time being.
