INVISIBLE IS POSSIBLE

By atla Praveen kumar(iiiyearece a)

This is another latest technology which changes another science fiction to reality. Invisibility has long been

employed in works of science fiction and fantasy, from “cloaking devices” on spaceships in the various Star Trek series to Harry Potter’s magic cloak. The theory of

making the things invisible is called as cloaking. And the device used for cloaking is said to be cloaking device.

A cloaking device is a theoretical or fictional stealth

technology that can cause objects, such as spaceships or individuals, to be partially or wholly invisible to parts of

the electromagnetic(EM) spectrum.To achieve the feat of “cloaking” an object, they have developed what are known

as “metamaterials”. These are the artificial materials which have the ability of bending electromagnetic radiation, such

as light, around an object, giving the appearance that it isn’t there at all.

The below fig. shows the example of cloaking:-

BASIC WORKING OF METAMATERIALS: The metamaterials do not obey the snell’s law thus its

behaviour is different from all other normal materials. That this shown in below figure

According to the snell’s law the refractive index of all

the materials should always be greater than 1 but the above figure shows that the refractive index of the meta

materials is negative which arises its unique property of refracting the light rays in completely different direction.

Cloaking can be achieved by cancellation of the electric

and magnetic field generatedby an object or by guiding the electromagnet wave around the object. Guiding thewave

means transforming the coordinate system in such a way that inside the hollowcloak electromagnetic field will be

zero this makes the region inside the shelldisappear. As shown in the figure

THE VARIOUS APPLICATIONS OF THE METAMATERIALS THAT CAN CHANGE WORLD IN THE UPCOMING YEARS

ARE GIVEN BELOW: 1. To construct satellite trackers that never need to move.

This can serve as portable energy efficient satellite communication units for the soldier on the battlefield.

2. Enable ULTRA FAST DATA PROCESSING. Metamaterials can reduce the size of the chips so that

they are tiny and speedy. 3. Beam broadband connections to planes, ships and

cars. Having high speed internet everywhere. 4. Create a camera that uses compressed microwave

images without a lens or moving parts. This can replace the bulky gateways currently in use in

airports. 5. Become the building blocks of high speed fibre optic

telecommunication networks. 6. Contribute in making of efficient solar cells less bulky.

Thus in future world, metamaterials have ability to change

the world.

EPIDERMAL ELECTRONICS

By Archana,iiiece

“Any sufficiently AdvAnced technology is indistinguishAble

frommAgic.”

― Arthur C. Clarke, Profiles of the Future: An Inquiry Into the

Limits of the Possible

Modern medicine and technology seem inseparable.

Technology has been transforming health care industry.

Here is yet another invention in the Healthcare Technology.

A team of researchers in the Cockrell School of Engineering

at The University of Texas at Austin has invented a method

for producing inexpensive and high-performing wearable

patches that can continuously monitor the body's vital

signs for human health and performance tracking,

potentially outperforming traditional monitoring tools such

as cardiac event monitors.

The researchers published a paper on their patent-pending

process inAdvanced Materials on Sept. 23.

Led by Assistant Professor Nanshu Lu, the team's manufacturing method aims to construct disposable tattoo-

like health monitoring patches for the mass production of epidermal electronics, a popular technology that Lu helped

develop in 2011.

The team's breakthrough is a repeatable "cut-and-paste"

method that cuts manufacturing time from several days to only 20 minutes. The researchers believe their new method

is compatible with roll-to-roll manufacturing -- an existing method for creating devices in bulk using a roll of flexible

plastic and a processing machine.

Reliable, ultrathin wearable electronic devices that stick to the skin like a temporary tattoo are a relatively new

innovation. These devices have the ability to pick up and transmit the human body's vital signals, tracking heart

rate, hydration level, muscle movement, temperature and brain activity.

Although it is a promising invention, a lengthy, tedious and

costly production process has until now hampered these wearables' potential.

"One of the most attractive aspects of epidermal electronics

is their ability to be disposable," Lu said. "If you can make them inexpensively, say for $1, then more people will be

able to use them more frequently. This will open the door for a number of mobile medical applications and beyond."

The UT Austin method is the first dry and portable process

for producing these electronics, which, unlike the current method, does not require a clean room, wafers and other

expensive resources and equipment. Instead, the technique relies on freeform manufacturing, which is similar in scope

to 3-D printing but different in that material is removed instead of added.

The two-step process starts with inexpensive, pre-

fabricated, industrial-quality metal deposited on polymer sheets. First, an electronic mechanical cutter is used to

form patterns on the metal-polymer sheets. Second, after removing excessive areas, the electronics are printed onto

any polymer adhesives, including temporary tattoo films. The cutter is programmable so the size of the patch and

pattern can be easily customized.

DejiAkinwande, an associate professor and materials expert in the CockrellSchool, believes Lu's method can be

transferred to roll-to-roll manufacturing.

"These initial prototype patches can be adapted to roll-to-roll manufacturing that can reduce the cost significantly

for mass production," Akinwande said. "In this light, Lu's invention represents a major advancement for the mobile

health industry."

After producing the cut-and-pasted patches, the researchers tested them as part of their study. In each test,

the researchers' newly fabricated patches picked up body signals that were stronger than those taken by existing

medical devices, including an ECG/EKG, a tool used to assess the electrical and muscular function of the heart.

The team also found that their patch conforms almost perfectly to the skin, minimizing motion-induced false

signals or errors.

The UT Austin wearable patches are so sensitive that Lu

and her team can envision humans wearing the patches to more easily maneuver a prosthetic hand or limb using

muscle signals. For now, Lu said, "We are trying to add more types of sensors including blood pressure and oxygen

saturation monitors to the low-cost patch." Thus we can conclude that this innovation will be highly cost efficient

and has got potentials for advancement in the future.

HOME SECURITY SYSTEM USING MICRO

CONTROLLERE

By G.ARAVIND ,IV ECE A

The microcontroller based digital lock for Doors is an

access control system that allows only authorized persons

to access a restricted area.An electronic lock or digital lock

is a device which has an electronic control assembly

attached to it. They are provided with an access control

system. This system allows the user to unlock the device

with a password. The major components include a Keypad,

LCD and the controller PIC16F877A.The system is fully

controlled by the 8 bit microcontroller 16F877A which has

an 8Kbytes of ROM for the program memory. The password

is stored in the EPROM so that we can change it at any

time. The system has a Keypad by which the password can

be entered through it. When they entered password equals

with the password stored in the memory then the relay gets

on and so that the door is opened.

Technology around the World

By s.dhilipkumar,AP/ece

Ultra-fast Wireless communication

A collaboration between US and Japanese researchers,

have developed a key component in order to enable wireless

communications which operate up to 100x faster than

current generation routers. Current wireless

communications operate at microwave frequencies,

however as the demand for faster speeds and larger

bandwidths increases, scientists are looking for ways to

alleviate the communication bottleneck. Between the

microwave and infrared part of the electromagnetic

spectrum lies an appealing candidate: Terahertz (THz)

radiation.

Oscillating at around 1 trillion times per second, THz waves

were previously utilized for the wireless data transmission

world record, whereby a team of researchers showed local

data transmission could be up to 100GBit/s. However, for

any real world system, electronic components are required

which perform common functions akin to our regular

communication technology; such as transmission,

multiplexing, demultiplexing, detection, processing etc.

The device created here is a modification of a common type

of antenna designed to operate at THz

wavelengths. Termed a “Leaky wave antenna”, the device is

made from two parallel metal plates, forming a waveguide.

One of the plates has a small slit in it and as the

THZ waves travel down the waveguide, some of the

radiation leaks out. The angle the radiation leaks out is

dependent on its frequency, hence 10 different frequencies

will radiate at 10 different angles (demultiplexing) and by

reversing the process the device can multiplex. A device

operating to multiplex/demultiplex between directional

free-space beams and a single-mode waveguide is

extremely appealing for real-world communication

applications.

The team hope that his early prototype device will kickstart

greater research into next generation THz based

communication networks.

Safety concern

This research is potentially an exciting development,

however there is a mixture of evidence to suggest whether

the interaction of THz radiation with biological organisms is

safe. A theoretical study published by MIT in 2009

suggested that THz waves may interfere with DNA via non-

linear instabilities, however the process was extremely

unlikely and required long exposure to the radiation. Until

sufficient experimental biological data is gathered, one

cannot be entirely certain as to the mechanisms involved,

however the consensus thus far because THz radiation is

non-ionizing is that damage to humans is extremely

unlikely.
