The concept uses a sensor to detect an explosion in water or air--say, an IED on the side of the road--then estimates the time and location of the explosion.
Next, the signal from the sensor triggers a laser (or a blast of electricity or microwave energy) that heats up a section of air or water

inspectors will have a better understanding of how a city's infrastructure is holding up GENESI is an awkward acronym for reen sensonr NETWORKS for Structural monitoring.
GENESI puts sensors into a city's various structures to let them"communicate"their status. These sensors include ibrating strain gauges, displacement meters, pressure sensors, temperature sensors,
and soil moisture sensors.""To conserve power, they have energy harvesting capabilities, and engineers can periodically wake them up to get fresh readings from the sensors and check for any changes.
One of GENESI two pilot projects is a testbed in the tunnels of Rome underground rail system,
where wire sensors that pick up strain from vibration were placed inside certain concrete segments. Data loggers record the data,
transmitting the information to a wireless setup and relay system, which then sends it out via cell networks to a remote server.
but powering sensors--even really efficient sensors--requires some form of electric charging or battery replacement.
But each GENESI node and sensor includes a miniature wind turbine that harvests energy from passing trains.

In some experiments, patients have been able to move prosthetic limbs just by thinking about it--a chip implanted in the brain translates the electricity in the brain motor cortex into instructions for the prosthetic to move.
The prosthetic hand contains torque sensors that can detect minute changes in pressure. Once the brain and arm were hooked up
DARPA engineers and scientists at Johns hopkins university Applied Physics laboratory first inserted electrodes into the patient motor cortex.
The hand contains sensors that can detect when pressure is being applied to its fingers, and converts this pressure into electrical signals that the brain implant reads.

#Open-source Soil Sensors: Vinduino As California fourth straight year of drought forces farmers to cut back on water use,
one California vineyard-owner has taken a DIY approach to creating a sensor-driven water conservation system.
The project so far includes instructions for making your own soil moisture sensors (based on the gypsum mineral found in plaster of paris;
building a handheld Arduino-based device for taking sensor readings; and creating Arduino-based irrigation valves,
water pressure sensors and data loggers for controlling and monitoring the vineyard irrigation system. In prototype stage is networked a,
solar-powered sensor reading station that can report Vinduino sensor data via the Thingspeak platform.
Van der Lee future plans include designing a network hub for collecting readings from multiple sensor stations,
Van der Lee says that one of his primary motivations for building Vinduino was to innovate on commercial soil monitoring systems that typically rely on readings from a single sensor.
Vinduino uses three sensors at different depths to get a better handle on the way water moves through the soil at each measurement point.
together with low cost gypsum soil moisture sensors, provides all that

The most sensitive commercial magnetic sensors require a single SQUID kept at 4. 2 Kn incredibly chilly temperature that is usually maintained with expensive and difficult to handle liquid helium.
"We believe there should be an immediate interest in the entire SQUID community for the potential replacement of their existing superconducting magnetic sensors based on single SQUIDS operating at 4. 2 K with our SQUID arrays operating at 77 K,
they provide a magnetic sensor that is very cost effective, considering that operation of SQUIDS at 4. 2k requires the use of liquid helium-4,

including computer chips and other optoelectronic components.""Our results demonstrate relatively fast modulation from fundamentally slow phosphorescent light emitters,
Phosphors are common light emitters used in light bulbs, LEDS and elsewhere. They are extremely efficient
One example could be optical communications networks on computer chips. Prototype on-chip networks have used semiconductor lasers as light emitters.
They can modulate very quickly, but they have downsides. Semiconductors can't be grown directly on a silicon chip,
so fabrication can be difficult. Using indirect means of modulation--interferometers, for example--makes for bulky systems that take up a lot of real estate on a chip.
What's more, semiconductor lasers are not particularly efficient. They produce a lot of heat along with light
which is a problem on a silicon chip. Erbium and other phosphors, on the other hand, can be deposited directly on silicon, making fabrication easier.
There's still more work to be done to get such a system up to a speed that would be useful on a chip,

'fluffy'carbon electrode made from graphene (comprising one-atom-thick sheets of carbon atoms), and additives that alter the chemical reactions at work in the battery,
a positive electrode, a negative electrode and an electrolyte,''said Dr. Tao Liu, also from the Dept. of Chemistry,
the negative electrode is made of graphite (a form of carbon), the positive electrode is made of a metal oxide, such as lithium cobalt oxide,
and the electrolyte is a lithium salt dissolved in an organic solvent. The action of the battery depends on the movement of lithium ions between the electrodes.
Li-ion batteries are light but their capacity deteriorates with age, and their relatively low energy densities mean that they need to be recharged frequently.
By precisely engineering the structure of the electrode, changing it to a highly porous form of graphene,
%The highly porous graphene electrode also greatly increases the capacity of the demonstrator, although only at certain rates of charge and discharge.
Other issues that still have to be addressed include finding a way to protect the metal electrode
which are generally harmful to the metal electrode.""There's still a lot of work to do, "said Liu."
which an electrode used for splitting water absorbs solar photons while at the same time improving the flow of electrons from one electrode to another.
"Excited electrons When building a sun-capturing electrode, scientists aim to use as much of the solar spectrum as possible to excite electrons in the electrode to move from one state to another,
where they will be available for the water-splitting reaction. Equally important, but a separate problem entirely, the electrons need to move easily from the electrode to a counter-electrode,
creating a flow of current. Until now, scientists have had to use separate manipulations to increase photon absorption

#Electronic skin sensors to control mobile gadgets A skin-worn sensor that turns the human body into a touch sensitive surface for controlling mobile devices has been developed by scientists in Germany. iskin is made from biocompatible silicone rubber
with pressure-sensitive sensors that are stuck to the skin of the users, allowing them to use their own body to control mobile devices.
The sensor is capable of detecting touch input pressure even when being stretched or bent. With the current prototypes;
"Current electronics are mostly using rigid components which are very uncomfortable to wear on the body
But our sensor is a flexible and stretchable sensor, so it can cover many locations.
So, we have a much larger input space than current electronics allow for, "he said. The prototype is based on advances in so-called'electronic skin'that allow robots to better sense their environment,
which makes up the sensor. This is then sandwiched between two clear sheets of silicone.""The sensor is made out of biocompatible silicone and carbon-doped silicone.
So there are carbon particles inside the silicone which make it conductive so we can use it for electronics,
"explained Weigel. The stickers are attached to the body using a medical-grade adhesive that can be peeled easily off after use without hurting the skin.
although the technology could evolve to use integrated microchips. Weigel also hopes that it could one day be possible to incorporate an energy harvesting system that would power iskin via the wear's body.

The top layer in the new work featured a sensor that can detect pressure over the same range as human skin,
and rubbers as pressure sensors by measuring the natural springiness of their molecular structures. They then increased this natural pressure sensitivity by indenting a waffle pattern into the thin plastic
This allowed the plastic sensor to mimic human skin, which transmits pressure information as short pulses of electricity, similar to Morse code, to the brain.
allowing more electricity to flow through the sensor, and those varied impulses are sent as short pulses to the sensing mechanism.
a flexible electronic circuit that could carry pulses of electricity to nerve cells. Bao's team has been developing flexible electronics that can bend without breaking.
For this project, team members worked with researchers from PARC, a Xerox company, which has a technology that uses an inkjet printer to deposit flexible circuits onto plastic.
Covering a large surface is important to making artificial skin practical and the PARC collaboration offered that prospect.
Bao's team envisions developing different sensors to replicate, for instance, the ability to distinguish corduroy versus silk,
And the inkjet printing fabrication process suggests how a network of sensors could be deposited over a flexible layer and folded over a prosthetic hand."
#Artificial'skin'Provides Prosthetics With Sensation Using flexible organic circuits and specialized pressure sensors, researchers have created an artificial skin"that can sense the force of static objects.
A particular challenge was creating sensors that can"feel"the same range of pressure that humans can.
Thus, on the sensors, the team used carbon nanotubes molded into pyramidal microstructures, which are particularly effective at tunneling the signals from the electric field of nearby objects to the receiving electrode in a way that maximizes sensitivity.
Transferring the digital signal from the artificial skin system to the cortical neurons of mice proved to be another challenge,
and initiatives-it can be reached through low-power radios, small antennas, and computer laptops if you have the technical know-how.

"The trick in getting them to be nearly transparent is in making them really thin-the electrodes are just 80 nm
"How did they make the electrodes so thin? Back in 2013, the main component of the electrolyte for the battery's positive electrode was lithium iron phosphate,
and for the electrolyte used for the negative electrode, they used lithium titanate and lithium hexafluorophosphate-both
of which are used commonly in rechargeable lithium-ion batteries. For the prototype that was put on display in Tokyo last month,
they altered the transparent oxides used for the negative electrode to achieve incredibly thin, transparent electrodes.

#Australian engineers just built a quantum logic gate in silicon for the first time For decades, researchers have been trying to build a computer that harnesses the enormous potential of quantum mechanics.
by creating a quantum logic gate in silicon-the same material that today's computer chips are made from.
which means they now have the ability to build the world's first quantum processor chip and, eventually, the first silicon-based quantum computer.
Right now, regular computer chips store information as binary bits, which are either in a 0 or 1 state.
what's known as a logic gate-a building block of all digital circuits, which takes two input values
Quantum logic gates have been built in the past, but they've all used exotic materials, which isn't compatible with today's silicon-based computer infrastructure.
A silicon quantum logic gate was the last physical building block remaining to be built in order to create a silicon-based quantum computer."
"Because we use essentially the same device technology as existing computer chips, we believe it will be much easier to manufacture a full-scale processor chip than for any of the leading designs,
which rely on more exotic technologies, "project leader Andrew Dzurak said in a press release.""This makes the building of a quantum computer much more feasible,
"The challenge in building quantum logic gates is the fact that, in order to get two qubits to'talk'to each other,
The team overcame this by effectively copying the setup of traditional chips. In that setup, binary bits are defined by tiny semiconductor devices known as transistors.
About 1 billion of these transistors has been packed onto each silicon chip in your smartphone or computer.
Quantum bits, on the other hand are defined by the spin of a single electron. But by reconfiguring traditional transistors to only be associated with one electron,
Dzurak and his team were able to have them define qubits instead. ee morphed those silicon transistors into quantum bits by ensuring that each has only one electron associated with it.
We then store the binary code of 0 or 1 on the'spin'of the electron,
The team then showed that they could use metal electrodes on these transistors to control the qubits
creating a functioning logic gate. The researchers have patented already a design"for a full-scale quantum computer chip that would allow for millions of our qubits,
Once we have a silicon quantum chip, we'll then be able to build a functioning quantum computer,

#Future electronics based on carbon nanotubes First of all they are tiny--on the atomic scale and perhaps near the physical limit of how small you can shrink a single electronic switch.
Like silicon, they can be semiconducting in nature, a fact that is essential for circuit boards, and they can undergo fast and highly controllable electrical switching.
But a big barrier to building useful electronics with carbon nanotubes has always been the fact that
a certain portion of them will act more like metals than semiconductors--an unforgiving flaw that fouls the film,
shorts the circuit and throws a wrench into the gears of any potential electronic device. In fact, according to University of Illinois-Urbana Champaign professor John Rogers, the purity needs to exceed 99.999 percent--meaning even one bad tube in 100,000 is enough to kill an electronic device."
"If you have lower purity than that, "he said, "that class of materials will not work for semiconducting circuits."
but fell far short of the level of purification necessary to make useful electronic components. Very recent approaches offer the right level of purification
They tested it by building arrays of transistors he said.""You end up with a device that can switch on and off as expected, based on purely semiconducting character,
