Technology is rapidly growing in the world.There might be some day in which things happen like self healing of electronics from damages due to temperature issues. The day is not so far..!!
University of Illinois engineers were able to create a method in which electronics with damaged circuits would be able to automatically repair themselves.The another shocking thing in this is that they are going to heal themselves with in 100 microseconds (100x10^-6 sec).
So in the upcoming years all the electronic gadgets uses this type of technology so that the gadgets will have long life and more durable.
The self healing technology involves creating circuits with gold lining and a layer of micro capsules. The damage for the circuits is mainly due to temperature effect. i.e circuits will get heated up and the heat will damage or cracks the circuit.
When such things happen due to temperature the microcapsules will automatically disperse themselves into the cracks, filling the gap and restoring conductivity to the circuit.
A group of scientists at Korea Advanced Institute of Science and Technology (KAIST) has fabricated a working computer chip that is almost completely clear, the first of its kind. The new technology, called transparent resistive random access memory (TRRAM).
The new chip is similar in type to an existing technology known as complementary metal-oxide semiconductor (CMOS) memory common commercial chips that provide the data storage for USB flash drives and other devices. Like CMOS devices, the new chip provides "non-volatile" memory, meaning that it stores digital information without losing data when it is powered off. Unlike CMOS devices, however, the new TRRAM chip is almost completely clear."It is a new milestone of transparent electronic systems," says researcher Jung Won Seo, who is the first author on the paper. "By integrating TRRAM device with other transparent electronic components, we can create a total see-through embedded electronic system."
"We are sure that TRRAM will become one of alternative devices to current CMOS-based flash memory in the near future after its reliability is proven and once any manufacturing issues are solved," says Professor Jae-Woo Park, who is Seo's co-advisor and co-author on the paper. He adds that the new devices have the potential to be manufactured cheaply because any transparent materials can be utilized as substrate and electrode. They also may not require incorporating rare elements such as Indium.
The fabricated TRRAM has a transmittance of 81% (including the substrate) in the visible region and an excellent switching behavior under3 V. The retention measurement suggests that the memory property of the TRRAM device could be maintained for more than 10 years. We believe that the TRRAM device presented in this work could be a milestone of future see-through electronic devices.
I think in future the iphone may be like the below image..!! :P
Intel may unveil its next generation of processors--nicknamed "Ivy Bridge"--in April, according to the latest reports. The Ivy Bridge chips for desktops and laptops promise a 37 percent performance increase over the current generation of Sandy Bridge processors.
The new Ivy Bridge CPUs use a 22-nanometer architecture, which makes them almost 30 percents smaller than the current chips, which use a 32nm architecture. Smaller chips mean lower power consumption (which is great for battery life) and more room for the integrated graphics chip. Ivy Bridge will support DirectX 11, Thunderbolt, and USB 3.0.
Taiwan-based trade publication DigiTimes reports that the first Ivy Bridge processors to launch will be quad-core desktop processors: the Core i7-3370 series and the Core i5-3570, 3550, and 3450. Because Ivy Bridge is backward-compatible with existing Sandy Bridge motherboards, desktop users should have an upgrade path available.
The first Ivy Bridge notebook chips to launch, according to DigiTimes, will be the Core i7 chips as well: The Core i7-3920QM, 3820QM, and 3720QM. Core i5 processors will pop up later.
Ivy Bridge will be smaller, more powerful, and more energy-efficient, and should be here in just a few months.

A Voltage Controlled Oscillator (VCO) is an oscillating circuit whose output frequency changes in direct proportion to an input voltage. VCOs can be made to oscillate from a few Hertz to hundreds of GHz. Every wireless device in use today has some sort of voltage controlled oscillator inside it. For example, there is a least one VCO inside every cell phone that generates the Radio Frequency (RF) waves that are used to communicate by-directionally to the cell tower.
Here today i am going to share Voltage Controlled Oscillator circuit using IC-555 timer.
It is basically an Astable Multivibrator circuit with variable control voltage.We know that internally set voltage at the control voltage terminal is 2/3 Vcc. In this circuit, the control voltage is externally set by the potentiometer. With change in the control voltage, the upper threshold voltage changes and thus the time required to charge capacitor up-to upper threshold voltage changes . Similarly discharge time also changes.As a result the frequency of output voltage changes.

Similarly discharge time also changes.As a result the frequency of output voltage changes.
If the control voltage is increased the capacitor will take more time to charge and discharge and therefore frequency will decrease. On the other hand if control voltage is decreased the capacitor will take less time to charge and discharge, increasing the frequency of output signal. Thus by varying the control voltage we can change the frequency.
What if every light bulb had its own unique Internet IP address? The possibilities are endless: You could monitor, manage and control every light bulb from any Internet-enabled device- turning lights on and off individually, dimming or creating scenes from your smartphone, tablet, PC or TV – to save energy as well as electricity costs.
NXP has unveiled technology that has to potential to provide every light bulb with its own IP address. In this
way, light bulbs could be controlled from any internet enabled device. The approach builds on its recent
acquisition of Jennic.
The technology, called GreenChip, is small enough to fit within the base of a regular energy efficient light
bulb. Two versions will be launched: GreenChip iCFL, for use with compact fluorescents (cfl); and GreenChip
iSSL, for use with leds. Both chipsets can act as dimmable drivers for smart lamps and are accompanied by:
a standby supply controller, with 10mW no load capability; a 2.4GHz IEEE802.15.4 compatible wireless
microcontroller; and wireless connectivity, enabled by the JenNet IP network layer software.
John Croteau, NXP’s general manager, power lighting solutions and high performance RF, said: “chipset has very low power consumption so it doesn’t negate the benefits of energy efficient lighting. And the cost structure is such that it can ship in consumer light bulbs.”
NXP is partnering with TCP, a leading manufacturer of cfl and led lamps. “TCP makes more than 1million
light bulbs a day,” said Croteau, “and will be launching consumer ready products. This is not a technology
demonstrator.” A further partnership with GreenWave Reality will see an intelligent lighting control and
management solution becoming available.
NXP will also making the technology available under an open source licence and will establish a
consortium to oversee its development. “There will not be an ‘internet of things’ if technology is proprietary or with royalties,” Croteau noted, adding “and if it only works with the iPhone, it won’t be deployable.”
NXP will be taking on ZigBee in the emerging wireless control sector, even though Croteau said this
wouldn’t be the case. “It’s not about competing with ZigBee,” Croteau claimed, “it’s about delivering
something people want to buy.”

One will accept that if i say that world today is totally dependent on the field of Electronics for almost all matters. And the electronic technology we use can be made simplified for our daily life activities.
Today i am going to show one such idea i.e. simplified battery using lemon.
Basically when two dissimilar metals are suspended in acid it forms the battery. So i am preparing a battery which is called as lemon battery.
Lemon contains citric acid and when two wires are connected across it we should get some voltage.
But the voltage we get is very small. And this experiment can be done on other items also like tomato etc which contains acid content in it. The voltage we get for different items are different. And if you ask what is use when small voltage is present as it is not capable of lighting a single bulb also?
But this voltage can be increased but connecting more and more lemons in series so that the voltage produced across them will be large enough to lit a bulb. And i have my first video tutorial on this experiment. You can see the proof of this post by watching the below video. :)
