Molecular Computers


In the near future computers may not be made of silicon but of DNA.DNA computers are much more faster and better than the traditional ones.

DNA is an information-rich molecule, and can be used for computing in a variety of ways. Computer chips are constructed using logic gates (such as AND, OR and NOT) that perform mathematical functions on given inputs. Similarly, these gates can be built from DNA, and connected up to run computations inside cells.


 

Brain-Computer Interface

 

Brain-computer interfaces(BCIs) plays a significant role in spinal cord injury,stroke or brain disease.It also helps to restore senses like sight or hearing or even memory.

BCIs implemented in brain's motor areas can record electrical signals thats represents particular movements. A computer decodes the signals and uses them to control a computer cursor or prosthetic limb.

The device would replace part of the brain's hippocampus, where short-term memory is converted to long-term memory. So far researchers has had success in rats and monkeys, and now they are  currently testing the device in humans.

Nanolasers on Silicon for Data Transmission

 

For quick transmission of data we rely on fiber optic cable.To ensure for more speed and seamless data flow researcher continue to new combinations of electronic and optical devices.

One of the promising research is growing lasers on silicon,the base layer of choice for electronic devices.

The lasers, called nanoneedles, are just one-tenth the width of a human hair and were developed by researchers working at the University of California, Berkeley. By growing lasers on silicon wafers, the researchers are expanding the ability of electronics to transmit data at capacities required by next-generation consumer devices and systems. 

Optical approaches such as lasers reduce power consumption and noise between components and increase speed.

To combine the strengths of silicon and optical laser materials, the Berkeley researchers overcame two longstanding challenges that have vexed researchers: 1) the mismatch between the crystalline structures of silicon and III-V semiconductor material, an essential solid-state laser material, and 2) growth temperatures that are incompatible with current integrated circuit fabrication. 
 
During the 10- to 15-minute crystal growth process, which occurs at temperatures between 400° and 450° C, nanoneedles in the shape of hexagonal pyramids emerge from a silicon base. These high-quality crystals can reach several hundred nanometers and can be layered, doped (i.e., other materials can be added to the crystal during the growth process, resulting in a crystal that has additional properties) or etched to create laser structures for device applications. The nanoneedle geometry provides a natural laser cavity that traps light by circulating it up and down the inside of the nanoneedle in a helical fashion.

Li-Fi

 

Instead of radio waves, use light to get online. Unlike wi-fi, or wireless fidelity, so-called “li-fi” transmits data through variations in light intensity.

Recent research in China  showed that, using a one-watt LED bulb, li-fi could connect four computers to the Internet at data transfer rates up to 150 megabits per second.

Earlier this year, German scientists sent data at three Gigabits per second using LED lamps, in controlled conditions in their lab. They later demonstrated 500 megabits per second speeds in a real-world setting. Most wi-fi connections don’t even come close to 100 megabits per second.

Li-fi has drawbacks. The technology works only when the LED’s light can reach the gadget. Stray from the LED, and you lose your connection. On the plus side, the visible light spectrum can handle way more traffic than wi-fi’s already crowded radio spectrum. And any LED bulb can be a network connection.

BioLite CampStove

 

Stove with lots of technology in it.It runs on fuel you can pick up off the ground – twigs, bark or pinecones – providing you with a free, low-smoke fire.Its just take 5 minutes to boil a kettle.

But that’s not all – the BioLite also has a USB port and generates free electricity, which you can use to charge your phone, MP3 player or speakers.


Scanadu Scout

 

 

There are plenty of gadgets that monitor your fitness. Whether they track your heart rate, blood pressure or the number of steps you’ve taken, they all give you a pretty basic view of your activity. But what about your general health?

Designed by a collective of engineers, doctors and designers, the Scanadu Scout wants to be your personal electronic GP. By pressing it to your temple, the Scout will give you an accurate reading of pulse transit time, heart rate, electrical heart activity, temperature and blood oxygenation. This info in itself isn’t particularly useful, unless you’ve been nose-deep in some medical text books for the last year, so the Scout then analyses the data and tells you if you ought to head to the nearest hospital, or not.

There’ll be an add-on too, which will check your saliva for nasty bugs like streptococcus A, influenza B and adenovirus. They’re even working on an add-on to spot pregnancy complications.

All of the above is technically possible, and the collective data gathered from everyone using a Scanadu could reveal interesting trends in the state of the public’s health. But as with any mode of self-diagnosis, you should apply common sense. Either way, doctors might have to get used to hearing patients say: “I need an appointment. Scanadu says it’s serious”.

Chemical Scanner for Shopping

An Israeli inventor invented a tiny gadgets which allows a consumer to analyze the chemical composition of foods,drugs and other items.


The Gadgets called SCio an infrared spectrometer is being marketed for three applications-food,pharmaceuticals and horticulture,or the health of plants.Simply by pointing and clicking a miniature digital wand,users can see how many calories are in a piece of cheese or determine when a tomato will reach peak ripens.

SCio could have life saving uses such as identifying contaminated foods or determining whether a drug is counterfeit.

With the spectrometer, he said, you can just point the gadget at an item—without even necessarily knowing what it is. The device reads the item's molecular structure, matches the information to an ever-expanding database and then can send additional data to your smartphone.

Are you getting bored with making coffee daily in the morning?With this portable coffee machine that will be a thing of the past.

Making your coffee is easy. Just plug in the gadget, add water and coffee, and press the button.

3D Printers

In Last December,2013 Michigan Technological University announced their firsr 3D printer.However not many of these printers is available to the common peoples.

Rocket parts,Bionic ears and even toothbrushes were all successfully printed with 3D printer.

3D printers use a variety of very different types of additive manufacturing technologies, but they all share one core thing in common: they create a three dimensional object by building it layer by successive layer, until the entire object is complete. It’s much like printing in two dimensions on a sheet of paper, but with an added third dimension: UP. The Z-axis.

Each of these printed layers is a thinly-sliced, horizontal cross-section of the eventual object. Imagine a multi-layer cake, with the baker laying down each layer one at a time until the entire cake is formed. 3D printing is somewhat similar, but just a bit more precise than 3D baking.

 

                                      SMART ROBOTS

 

Quadcopters are quickly gaining popularity.consumers can look forward to smart quadcopters like Spiri.Spiri is a programmable flying robot that has an onboard camera and range finder to help you achieve whatever you program it to do.

Robot cubes that can move about on their own and assemble themselves into anything they are programmed to do. Magnets are used to attach the blocks to one another while flywheels inside the body of each cube generate enough momentum for them to move and even jump in the air.

There’s no real application to what these modular robots can actually do right now as it’s still in the very early stages of research, but this modular idea means that a machine isn’t limited to a single task but can assemble itself into another machine to achieve another task.

Do-it-yourself Stress Hormone Test by Your Smartphone

In a recent conference in USA  researchers said that health apps are coming in your smartphone for stress test.Anyone with a smartphone will be able to measure their salivary cortisol level quickly, easily and inexpensively

Parts of the United States and the rest of the world that lack facilities to measure cortisol will now be able to perform this essential diagnostic test.Measuring salivary cortisol with this technology will provide a way for individuals to monitor their personal biometric stress levels easily and inexpensively.

The public to monitor their own cortisol levels whenever they want. So they designed their device to be inexpensive to manufacture, and easy to use on all cell phones, all platforms and all form factors.

It consists of a case, a light pipe, and a lens, it uses no battery power and it’s unbreakable and reusable.

To take the test, a person puts a straw-like saliva collector under the tongue, and capillary action wicks the saliva to an assay strip in a cassette that's inserted into a reader; the reader aligns a lens and light diffuser with a smartphone’s camera and flash. A few minutes later, the smartphone image analysis app quantifies the cortisol value.

MRAM- Magnetoresistive Random Access Memory

Magnetoresistive Random Access Memory (MRAM) is a non-volatile computer memory (NVRAM) technology, which has been in development since the 1990s.


Unlike conventional RAM chip technologies data is not stored as electric charges but by magnetic charges.

In MRAM data can be stored in greater amount and can be accessed faster while consuming less battery power compare to conventional electronic  memory.

Conventional memory chips like RAM stores information as long as power is on,once power is turned off the information is lost unless it is stored in secondary memory.But in MRAM the information still remains in memory even when the power is turned off.

IBM,Motorola,Honeywell,HP,Hitachi,Siemens are working on MRAM.



                                            Electric Cars



 
From the Nissan LEAF to the BMW i3, 2013 started to bring electric cars more to the middle of the road.

As more charging points are rolled out across the country in 2014, expect the interest in these motors to increase.

As well as helping the environment, they keep the cost of driving low with no need for petrol or diesel.

All you do is plug them in overnight and off you go in the morning.
Of course, you have a limited range but they're great for local and short hopper journeys.

3-D printed wrist splints for arthritis 

A Loughborough University lecturer has developed a computer software concept that will enable clinicians with no experience in Computer Aided Design (CAD) to design and make custom-made 3D printed wrist splints for rheumatoid arthritis sufferers. The 3D printed splints are not only more comfortable and attractive but potentially cheaper than the current ones that are 'ugly, bulky, and can make a patients arm sweat'.

The splints, which provide joint protection, rest, and promote pain relief,could be a major boost for sufferers of rheumatoid arthritis.

The splints are made by scanning a patient's arm in the 'appropriate position'. A 3D model splint is then designed based on the scan to generate a computer model.

The 3D printer can then produce as many splints as are needed at the touch of a button. They can be any colour, feature multiple materials, have a lattice design to aid ventilation and any type of fastening the patient requires.

The 3D CAD software prototype was shown to certified splinting practitioners, such as occupational therapists and physiotherapists.

Musical Gloves for Patients with Spinal Cord Injury



The researchers from Georgia Institute of Technology have created a wireless musical glove that may improve sensation and motor skills for people with paralyzing spinal cord injury (SCI). 

The gadget was successfully used by individuals with limited feeling or movement in their hands due to tetraplegia. These individuals had sustained their injury more than a year before the study, a time frame when most rehab patients see very little improvement for the remainder of their lives. Remarkably, the device was primarily used while the participants were going about their daily routines.

The device is called Mobile Music Touch (MMT). The glove, which looks like a workout glove with a small box on the back, is used with a piano keyboard and vibrates a person’s fingers to indicate which keys to play. While learning to play the instrument, several people with SCI experienced improved sensation in their fingers.

The MMT system works with a computer, MP3 player or smart phone. A song, such as Ode to Joy, is programmed into a device, which is wirelessly linked to the glove. As the musical notes are illuminated on the correct keys on the piano keyboard, the gadget sends vibrations to "tap" the corresponding fingers. The participants play along, gradually memorizing the keys and learning additional songs.
