#Imec demoes full-colour OLEDS Imec and Fujifilm have demonstrated full-colour OLEDS by using their jointly-developed photoresist technology for organic semiconductors,
a technology that enables submicron patterning. This paves the way to producing high-resolution and large organic electroluminescent (EL) displays
There has been active R&d for organic semiconductors to develop a high-resolution patterning method for organic EL materials to be used in these products.
In 2013, Fujifilm and imec jointly developed photoresist technology for organic semiconductors that enables submicron patterning without damaging the organic semiconductor materials,
This is why the technology has attracted wide attention since the development announcement with anticipation of a cost-effective way of manufacturing high-resolution organic semiconductor devices.
In the latest achievement, Fujifilm and imec produced full-colour OLEDS with the photoresist technology for organic semiconductors
to create full-color OLEDS. An OLED array of 40 x 40 dots at the resolution of 640ppi was realized
and illuminated with UV rays to confirm that red, green and blue dots separately emitted light.
An example would be creating an OLED array that adds a fourth color to red
as well as developing previously-unseen devices such as a new sensors that integrate OLED with the organic photodetector o
#University embeds RFID chips in yarn Researchers at Nottingham Trent University have come up with a way of embedding RFID chips in yarns
Professor Tilak Dias of the Advanced Textiles Research Group of the School of art & Design, claims that the embedded chips annot be seen in situ by the naked eye He has patented the technology,
f an RFID chip is embedded into a shirt, for instance, it will provide a much greater level of anti-theft
As people will not be able to easily identify where a chip is located in a garment,
either side of the chips are embedded in yarn fibres and act as an antenna. Measuring one millimetre by 0. 5 millimetre in size
when bought in bulk the chips can cost only a few pence each. Similar to the RFID devices now used in bank cards for contactless payments,
the tiny chips can contain all the information which is communicated usually via barcode. n relation to recycled clothes,
charities would be able to sort garments much quicker perhaps even in an automated way to identify the types of clothing that are suitable for different countries according to their requirements,

According to chip supplier NXP: Existing automotive technologies and business models that have worked for the car industry for a century are not so well suited to a changing car market with autonomous vehicles and Iot-connected cars.
This will combine car makers with electronics firms and software services suppliers. No single sector will be able to capitalise on this market, due to its diversity and the range of technologies required.
Putting electronics management systems in cars was only the beginning. Connecting vehicles to the internet will add a far greater level of complexity to the automotive business model.

#Cardiac microchip provides advance warning of future heart problems A potentially lifesaving microchip has been developed to forewarn patients suffering from heart problems of any deterioration in their condition.
Reg Youngman is one of the first to try the microchip. A tiny micro sensor has been inserted into his pulmonary artery,
which monitors his heart function. Everyday he is scanned and his data is sent to his hospital and medical team,

These large-scale mining operations managed to further reduce costs by centralizing operations and paying lower utility rates.

#New graphene display creates LEDS at an atomic level Graphene has had a rough go of it of late.
This doesn mean that graphene has no electronics applications, however, and a research team from the University of Manchester has published a report detailing how flexible 2d graphene arrays could be used in the next-generation of LED screens.
the Cambridge Graphene Centre demonstrated a display that incorporated a graphene electrode. The new LEDS built by the University of Manchester in this experiment were engineered apparently at an atomic level from multiple layers of crystal lattice as shown below.
This type of structure implements multiple layers of materials horizontally, but because each lattice is only a few atoms thick,
The near-term applications of this technology could be in optoelectronics. Electron movement is controlled via quantum wells (a quantum well is a layer of material that constricts the movements of electrons to particular dimensions to ensure energy arrives where it meant to go).
the University of Manchester team certified that the graphene-based LEDS have remained robust and continued to emit light for weeks.
The team claims that these graphene-based LEDS can emit light across their entire surface (apparently obviating
and have reached efficiencies that are already comparable to organic LEDS in terms of quantum efficiency (photons emitted per electron injected).
Whether or not that means graphene-based LED TECHNOLOGY can supplant OLED is, of course, an open question.
While OLEDS have become popular in certain Samsung displays, the OLED revolution in mainstream television has yet to occur.
What was predicted once as The next Big Thing after 1080p has been supplanted largely by conventional LCD technology at higher 4k resolutions.
Right now. OLED has just one major vendor LG offering serious support, and that not enough to drive long-term R&d for continuing the technology in large panels.
It not clear if graphene LEDS can drive the rich, vibrant colors that have made OLEDS desirable,
but if they can, it possible that TV manufacturers will finally be able to deliver the promise of OLED in a different technology.
Of course, given the long lead time between research and commercialization, wee still talking about advances that could take five to ten years to hit the market i

#New microprocessor claims 10x energy improvement As power consumption has become one of the most important metrics of CPU design,
Now, one small embedded company, Ambiq Micro, is claiming to have made a breakthrough in CPU design by building a chip designed for subthreshold voltage operation with dramatic results.
Subthreshold and near-threshold voltage operation The threshold voltage of a transistor is the voltage point required to create a conducting path between the source and drain terminals.
which the transistor turns n. The voltage threshold is not an absolute, however operation is possible in both the near-threshold and subthreshold regions.

Bending light with a microchip The Defense Advanced Research Projects Agency (DARPA) has demonstrated solid-state optical phased array technology in a microchip bringing the ability to bend light to the battlefront.
But in the former case, radar antennas are used as the electrically tunable element. So what the big deal here?
DARPA breakthrough 3 uses a microchip to control the light, vastly different to existing methods.
and manufacturable through standard semiconductor processing. DARPA Short-range Wide-field-of-view Extremely agile Electronically steered Photonic Emitter (SWEEPER) program has integrated successfully nonmechanical optical scanning technology onto a microchip.
The SWEEPER technology has demonstrated that it can sweep a laser back and forth more than 100 000 times per second, 10,000 times faster than current state-of-the-art mechanical systems.
the widest field of view ever achieved by a chip-scale optical scanning system. DARPA foresees this technology will open up a new class of miniaturized, extremely low-cost, robust laser-scanning technologies (LIDAR),
which could lead to greatly enhanced capabilities for numerous military and commercial applications ncluding autonomous vehicles, robotics, sensors and high-data-rate communications.
Those researchers built a series of pipes for light (phase shifters) on a microchip, which is able to slows down
The timed light waves are delivered then to tiny array elements within a grid on the chip.
by means of a roll-on coating consisting of a honeycomb of electrodes (see bottom right image).
whereby opaque, charged particles (approx. 1 micron in size) are attracted to electrodes that posses an opposite charge.
Thus the electric field created between the two electrodes causes the flow of these particles back and forth.
The interaction of incoming light with each electrophoretic pixel (two electrodes) depends on the position of the particles relative to these electrodes,
In reference to these, the device uses electrophoresis to attract charged color particles to the top transparent electrode to preadtheir color,
which are adjacent to the electrode. The device is filled with dual-colour, dual-particle colloidal dispersion inks.
It is common in e-ink displays to use sub-pixels (i e. multiple electrodes to do some fancy charged transport),
They use three electrodes and by altering the applied voltages between them all, many color states are created during operation,
which is the same technology used to pattern microchips and is very expensive. But the design here can be integrated with HP roll-to-roll micro-patterning technique, a much cheaper and large scale alternative.
#Breakthrough quantum dot hybrid LED is inexpensive and delivers vibrant color Light-emitting diodes (LEDS) are prevalent in everything from digital clocks to solar panels, traffic lights, electronic banners and signs, Christmas decorations,
as well as smartphone and tablet displays. However, LEDS are created using organic materials that can be costly for researchers.
The end result of the manufacturing process is that LEDS cost more for the consumer.
While LED lighting systems last longer, are more energy-efficient, and provide an improved color gamut above that of fluorescent lights,
cost-effective quantum dot (QD) hybrid LED could enable LED lighting system adoption on a mass scale.
University of Hiroshima (Japan) researchers created the new light-emitting diode using silicon quantum dot solution and a polymer solution on top of an indium-tin-oxide (ITO) glass ply that was used as the anode for the LED.
The silicon quantum dot solution was placed in the bottom of a glass vial that sat on a rotating stage.
The study is the first of its kind to produce silicon quantum dot LEDS by way of a solution-based process
and marks an advancement of LED TECHNOLOGY, seeing that the use of organic film as the electron transport in past LED production resulted in a decreased photoluminescence and an inaccurate color reproduction.
resulting in a more cost-efficient process by which to manufacture LEDS. Fluorescent bulbs are cheaper than LEDS,
with a box of fluorescent bulbs costing no more than a few dollars, but consume more energy and lead to higher energy bills.
LEDS are more expensive up-front, with some costing as high as $70 a piece,
QLED TVS, like LED lighting systems, cost more up-front than traditional LCD TVS but are cost-efficient and color-effective.
Sony worked with Quantum dot supplier QD Vision to produce its own QD TVS in 2013 under the riluminouslabel,
but Samsung is one of the major manufacturers now advancing QD technology over OLED with the recent release of its Super Ultra High-Definition TVS (SUHD)
and the purchase of Utah-based LED digital billboard and message sign company Yesco Electronics in March n

and an elastic band that was pulled up from the wrist to the bicep, and stretched the lithium-ion battery to 150%of its original size.
and the Gear 2 smartwatch continued its video playback. ASU leader Dr. Jiang says that the kirigami-based design is the secret to the future of flexible electronics. he kirigami-based methodology can be expanded readily to other applications to develop highly stretchable devices
and thus deeply and broadly impact the field of stretchable and wearable electronics, he said. ther applications may include smart bracelets and smart headbands.
The results and other details regarding the study can be found in the Scientific Reports journal as well as Nature magazine.

Sinitskii turned these short whiskers into titanium trisulfide transistors, and tested their performance, confirming that they had expected the properties, and abilities.
What this means is that purely scientific proofs of concept like current graphene computer chips might be made fully digital
and off by the same process as a silicon transistor could let it power continued increases in processing speed without requiring engineers to invent a whole new sort of logical architecture.
In theory, the success with simple transistors implies that this material could also help continue advances in solar cells.

but such technologies change the transistor design, and thus the manufacturing process for solar panels. Their impacts tend to be limited by cost concerns, more than anything else.
These researchers chose to accept the absorptive abilities of current silicon transistors, and instead looked to make the light conform to the panels.
there is huge potential in offering such large improvements without the need to completely reinvent the transistor manufacturing process.

Wi-fi radio broadcasts are a form of energy that a simple antenna can pick up. Until now, Wi-fi receivers have all been designed to harvest the information that these broadcasts carry.
Talla simply connected an antenna to a temperature sensor placed it close to a Wi-fi router
and measured the resulting voltages in the device and for how long it can operate on the remote power source alone.
Even more ambitiously, the team also connected a camera to their antenna. This was a low-power sensor capable of producing 174×144 pixel black and white images,
which requires 10.4 millijoules of energy per picture. To store energy, they attached a low leakage capacitor to the camera
which activates when the capacitor is charged and continues operating until the voltage drops to 2. 4 Volts.
The images were stored in a 64kb random access memory (RAM. In the subsequent tests, the camera performed remarkably well. he battery-free camera can operate up to about five meters from the router,
perhaps connected to a movement sensor to trigger the camera when something moves in its field of view,
