#Scientists made a major breakthrough in 3d-printed electronics that will keep you from ever drinking spoiled milk again Researchers have used 3d printing to develop a sensor that can be placed inside a carton of milk to detect

This represents a breakthrough in terms of three dimensional printing of electronic circuits. Polymers are poor conductors of electricity

whereas flat plates made for useful capacitors. The basis of this led to the production of the sensor cap for milk cartons.

The sensor functioned by detecting an increase in level of electrical signal as would be accompanied by a growth in bacterial population.

When this occurs a signal can be sent wirelessly. Sung-Yueh Wuuc Berkeley engineers created a mart capusing 3d-printed plastic with embedded electronics to wirelessly monitor the freshness of milk.

The sensor was tested on various cartons of milk, some held at room temperature and some in a refrigerator.

It was found that the cartons kept at room temperature produced the electrical signal far earlier

"The study was conducted at UC Berkeley (the Berkeley Sensor and Actuator Center) together with Taiwan's National Chiao tung University.

The research has been published in the journal Microsystems & Nanoengineering, in an article headed"3d-printed microelectronics for integrated circuitry and passive wireless sensors. e

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.

Light emitting diodes (LEDS) are now everywhere from consumer electronics like smart phones to light bulbs for home lighting.

The key to its success in replicating a sunny sky uses nanostructured materials to scatter light from LEDS in the same way tiny particles scatter sunlight in the atmosphere so-called Rayleigh scattering.

Illuminating research Only recently has the full utility of LEDS been realized for general lighting. While red and green LEDS had been in commercial use for more than a decade,

the missing color for producing white light was blue. Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura cracked the blue conundrum in the early 1990s.

Now, thanks to their work, white light LEDS are ubiquitous. In recognition of this energy saving invention, they received the Nobel prize in Physics last year.

Take LEDS for example. Research in blue LEDS started more than 40 years ago at Radio Corporation of America,

but changes in the company funding structure stymied their development for two decades until last year Nobel prize winners solved the materials problem

That such nanostructures could even be made is because of the decades-long investment by the electronics industry in developing nanofabrication tools to make the tiny components in computers.

#Researchers develop a semiconductor chip made almost entirely of wood Portable electronics-typically made of nonrenewable,

In an effort to alleviate the environmental burden of electronic devices, a team of University of Wisconsin-Madison researchers has collaborated with researchers in the Madison-based U s. Department of agriculture Forest Products Laboratory (FPL) to develop a surprising solution:

a semiconductor chip made almost entirely of wood. The research team, led by UW-Madison electrical

and computer engineering professor Zhenqiang"Jack"Ma, described the new device in a paper published May 26, 2015 by the journal Nature Communications("High-performance green flexible electronics based on biodegradable

or support layer, of a computer chip, with cellulose nanofibril (CNF), a flexible, biodegradable material made from wood."

"The majority of material in a chip is support. We only use less than a couple of micrometers for everything else,

"Now the chips are so safe you can put them in the forest and fungus will degrade it.

"Working with Shaoqin"Sarah"Gong, a UW-Madison professor of biomedical engineering, Cai's group addressed two key barriers to using wood-derived materials in an electronics setting:

CNF offers many benefits over current chip substrates, she says.""The advantage of CNF over other polymers is that it's a bio-based material and most other polymers are based petroleum polymers.

"The group's work also demonstrates a more environmentally friendly process that showed performance similar to existing chips.

The majority of today's wireless devices use gallium arsenide-based microwave chips due to their superior high-frequency operation and power handling capabilities.

However, gallium arsenide can be environmentally toxic, particularly in the massive quantities of discarded wireless electronics.

"I've made 1, 500 gallium arsenide transistors in a 5-by-6 millimeter chip. Typically for a microwave chip that size,

there are only eight to 40 transistors. The rest of the area is wasted just, "he says."

and make a completely functional circuit with performance comparable to existing chips.""While the biodegradability of these materials will have a positive impact on the environment,

Ma says the flexibility of the technology can lead to widespread adoption of these electronic chips."

"Mass-producing current semiconductor chips is so cheap, and it may take time for the industry to adapt to our design,

"But flexible electronics are the future, and we think we're going to be well ahead of the curve

#An easy, scalable and direct method for synthesizing graphene in silicon microelectronics: Korean researchers grow 4-inch diameter, high-quality, multi-layer graphene on desired silicon substrates,

an important step for harnessing graphene in commercial silicon microelectronics Abstract: In the last decade, graphene has been studied intensively for its unique optical, mechanical, electrical and structural properties.

The one-atom-thick carbon sheets could revolutionize the way electronic devices are manufactured and lead to faster transistors, cheaper solar cells, new types of sensors and more efficient bioelectric sensory devices.

As a potential contact electrode and interconnection material, wafer-scale graphene could be an essential component in microelectronic circuits,

but most graphene fabrication methods are not compatible with silicon microelectronics, thus blocking graphene's leap from potential wonder material to actual profit-maker.

Now researchers from Korea University in Seoul, have developed an easy and microelectronics-compatible method to grow graphene

and have synthesized successfully wafer-scale (four inches in diameter), high-quality, multi-layer graphene on silicon substrates.

which ions are accelerated under an electrical field and smashed into a semiconductor. The impacting ions change the physical, chemical or electrical properties of the semiconductor.

In a paper published this week in the journal Applied Physics Letters, from AIP Publishing,

which takes graphene a step closer to commercial applications in silicon microelectronics.""For integrating graphene into advanced silicon microelectronics, large-area graphene free of wrinkles, tears and residues must be deposited on silicon wafers at low temperatures,

which cannot be achieved with conventional graphene synthesis techniques as they often require high temperatures, "said Jihyun Kim, the team leader and a professor in the Department of Chemical and Biological engineering at Korea University."

"Our work shows that the carbon ion implantation technique has great potential for the direct synthesis of wafer-scale graphene for integrated circuit technologies."

Graphene's unique optical, mechanical and electrical properties have lead to the one-atom-thick form of carbon being heralded as the next generation material for faster, smaller, cheaper and less power-hungry electronics."

"In silicon microelectronics, graphene is a potential contact electrode and an interconnection material linking semiconductor devices to form the desired electrical circuits,

#Toward tiny, solar-powered sensors The latest buzz in the information technology industry regards he Internet of thingsthe idea that vehicles, appliances, civil-engineering structures, manufacturing equipment,

and even livestock would have embedded their own sensors that report information directly to networked servers,

however, will require extremely low-power sensors that can run for months without battery changes or, even better,

this new chip can do both, and it can power the device directly from the battery.

All of those operations also share a single inductor the chip main electrical component which saves on circuit board space

the chip power consumption remains low. e still want to have battery-charging capability, and we still want to provide a regulated output voltage,

and we really want to do all these tasks with inductor sharing and see which operational mode is the best.

The prototype chip was manufactured through the Taiwan Semiconductor Manufacturing Company's University Shuttle Program. Ups and downs The circuit chief function is to regulate the voltages between the solar cell, the battery,

To control the current flow across their chip, El-Damak and her advisor, Anantha Chandrakasan,

the Joseph F. and Nancy P. Keithley Professor in Electrical engineering, use an inductor, which is a wire wound into a coil.

When a current passes through an inductor, it generates a magnetic field which in turn resists any change in the current.

Throwing switches in the inductor path causes it to alternately charge and discharge, so that the current flowing through it continuously ramps up

however, the switches in the inductor path need to be thrown immediately; otherwise, current could begin to flow through the circuit in the wrong direction,

El-Damak and Chandrakasan use an electrical component called a capacitor, which can store electrical charge.

The higher the current, the more rapidly the capacitor fills. When it full, the circuit stops charging the inductor.

The rate at which the current drops off however, depends on the output voltage, whose regulation is the very purpose of the chip.

Since that voltage is fixed, the variation in timing has to come from variation in capacitance.

El-Damak and Chandrakasan thus equip their chip with a bank of capacitors of different sizes.

As the current drops, it charges a subset of those capacitors, whose selection is determined by the solar cell voltage.

Once again, when the capacitor fills, the switches in the inductor path are flipped. n this technology space,

there usually a trend to lower efficiency as the power gets lower, because there a fixed amount of energy that consumed by doing the work,
