#Ultrafast Line Scan Sensor from Fraunhofer Identifies Faulty Safety Features in Banknotes In the first half 2014 alone,
For the development of a new sensor, the Austrian research institution has brought the Fraunhofer Institute for Microelectronic Circuits and Systems IMS in Duisburg on board.
This is because the sensors which are currently available have reached meanwhile their limits: their speed is often not enough to check quality in real-time during the production process.
Camera takes 200,000 color images per secondwith the 60-line sensor that the Duisburg experts have developed,
ur sensor is twice as fast as currently available solutions, while providing high-quality images in very high resolution, explains Werner Brockherde from the IMS.
The sensor detects the bills like a scanner does line by line when they come off the press.

#New MIT Power Converter Chip Harvests More than 80%of Energy Realizing that vision, however, will require extremely low-power sensors that can run for months without battery changes or, even better,
that can extract energy from the environment to recharge. Last week, at the Symposia on VLSI Technology And circuits, MIT researchers presented a new power converter chip that can harvest more than 80 percent of the energy trickling into it,
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
Nonetheless, 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.
at very limited input power levels 10 nanowatts to 1 microwatt for the Internet of things. he prototype chip was manufactured through the Taiwan Semiconductor Manufacturing Company's University Shuttle Program.
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,

#New Conductive Ink Can Print Sensors Onto Wearables Researchers at the University of Tokyo have invented a new conductive ink that can be used to print sensors onto wearable technologies.
The ink will be used in printed electronics, which will allow sensors to be incorporated into electronic apparel for measuring biological data,
including heart rate and muscle contraction. At present, printed electronics, including LEDS, solar panels and transistors, are printed mainly on hard or rigid materials, such as paper or plastics.
For wearable devices, materials would need to be soft and stretchy to be comfortable and well fitting
but it has been challenging to produce an ink that is elastic as well as conductive and can be printed in a simple, single step process.
The team used this ink to produce a wrist-band muscle activity sensor. An elastic conductor was printed onto sportswear material,
and this was combined with an organic transistor amplifier circuit. The sensor features nine electrodes that are placed 2 cm apart from one another in a 3 x 3 grid
and can detect muscle electrical potentials to measure muscle activity y

%Using sensors, analytics and real-time data helps industrial automation companies anticipate failures and respond more quickly to critical situations
Kathryn believes that new research integrating electronics directly into the fabric of clothing could move us a step closer to this smart technology.
Sensors can provide detailed real-time information about a patient, alerting medical professionals if there is a warning sign, for example high blood pressure or swelling.
But we are yet to see sensors that can pick out minor physiological fluctuations, while integrating into everyday life.
Smart textiles, which allow accurate and reliable electronic sensors to be built into everyday clothing, could be the solution.
"Circuit printing opens up a myriad of possibilities as it allows a network of sensors to be positioned precisely across the area to be monitored,
which brought together NPL's Electronics Interconnection Group and Coventry University's Functional Materials Group to work on smart textiles.
#Prototype Ultrasound Sensors Developed for New Improved Breast Screening Technique NHS breast cancer screening in England is conducted currently using X-ray mammography,
and patented a novel detection method employing pyroelectric sensors, which convert ultrasonic energy into heat,
These large-area thermal sensors should generate far fewer image artefacts than conventional piezoelectric detectors
In the new procedure, the patient's breast will be placed in a warm water bath between an ultrasound transmitter and receiver.
and the amount of energy emerging is measured using the prototype ultrasound sensor. The ultrasound transmitter array and the receiver are rotated around the breast,

which converts video images from a miniature video camera worn on his glasses. He can now make out the direction of white lines on a computer screen using the retinal implant.
The images are converted into electrical pulses and transmitted wirelessly to an array of electrodes attached to the retina.
The electrodes stimulate the remaining retina's remaining cells which send the information to the brain.
At present, level designs are limited by how much data can be stored in the RAM-or, strictly, a type of RAM chip called dynamic RAM (DRAM.
3d XPOINT does away with the need to use the transistors at the heart of Nand chips.
Nand works by moving electrons back and forth to an isolated part of the transistors known as their"floating gates"to represent the ones and zeros of binary code.
RAM's speed advantage over traditional storage has made long it the chip of choice to funnel data directly into processors.
One instance when you might want to use the new chips instead of flash would be to store operating system files that are required every time you boot up your machine.
A loop of microtubules encircles the inner plasma membrane of the terminal and anchors mitochondria. Researchers have discovered a thick band of microtubules in certain neurons in the retina that they believe acts as a transport road for mitochondria that help provide energy required for visual processing.
which store the transmitters that convey information between neurons. An intriguing new study of their subcellular structure could help explain how bipolar synaptic terminals meet such excessive energy demands.
Using cutting-edge 3d microscopy, researchers from the National Heart Lung, and Blood Institute and Yale university examined the subcellular architecture of presynaptic terminals in retinal bipolar cells of live goldfish.
Goldfish retinal bipolar cells have giant presynaptic terminals that make them especially amenable for investigation.
Unexpectedly, the team discovered a thick band of microtubules, a component of the cell's cytoskeleton,
that extended from the axon of the neuron into the synaptic terminal and then looped around the interior periphery of the terminal.
The microtubule band appeared to associate with mitochondria--organelles known for providing energy to cells--in the synaptic terminal.
and never made it to the synaptic terminal. The findings suggest that these previously unknown microtubule structures provide a"roadway"for the transport of mitochondria crucial to maintain energy supplies into the synaptic terminals of these highly active neurons associated with vision.

#Major Step for Implantable Drug Delivery Device An implantable, microchip-based device may soon replace the injections
Earlier this month, MIT spinout Microchips Biotech partnered with a pharmaceutical giant to commercialize its wirelessly controlled, implantable,
microchip-based devices that store and release drugs inside the body over many years. Invented by Microchips Biotech cofounders Michael Cima, the David H. Koch Professor of Engineering,
and Robert Langer, the David H. Koch Institute Professor, the microchips consist of hundreds of pinhead-sized reservoirs,
each capped with a metal membrane, that store tiny doses of therapeutics or chemicals. An electric current delivered by the device removes the membrane,
and osteoporosis. Now Microchips Biotech will begin co-developing microchips with Teva Pharmaceutical, the world largest producer of generic drugs,
Apart from providing convenience, Microchips Biotech said these microchips could also improve medication-prescription adherence a surprisingly costly issue in the United states. A 2012 report published in the Annals of Internal medicine estimated that Americans who don stick to prescriptions rack up $100 billion
Microchips Biotech will continue work on its flagship product, a birth-control microchip, backed by the Bill and Melinda Gates Foundation,
Cima, who now serves on the Microchips Biotech board of directors with Langer, sees this hormone-releasing microchip as one of the first implantable rtificial organsbecause it acts as a gland. lot of the therapies are trying to chemically trick the endocrine systems Cima said. e are doing that with this artificial organ we created.
Wild ideas Inspiration for the microchips came in the late 1990s, when Langer watched a documentary on mass-producing microchips. thought to myself,
ouldn this be a great way to make a drug-delivery system??Langer said. He brought this idea to Cima,
a chip-making expert who was taken aback by its novelty. ut being out-of-this-world is not something that needs to stop anybody at MIT,
Cima adds. n fact, that should be the criterion. So in 1999, Langer, Cima, and then-graduate student John Santini Phd 9 co-founded Microchips,
and invented a prototype for their microchip that was described in a paper published that year in Nature.
This entrepreneurial collaboration was the first of many for Cima and Langer over the next decade.
For years, the technology underwent rigorous research and development at Microchips Biotech. But in 2011, Langer and Cima,
and researchers from Microchips, conducted the microchipsfirst human trials to treat osteoporosis this time with wireless capabilities.
In that study, published in a 2012 issue of Science Translational Medicine, microchips were implanted into seven elderly women,
Results indicated that the chips delivered doses comparable to injections and did so more consistently with no adverse side effects.
That study, combined with ongoing efforts in contraceptive-delivery microchips, led Cima to believe the microchips could someday,
essentially, be considered the first artificial glands that could regulate potent hormones inside the body. This may sound like a wild idea but Cima doesn think so.
The chip ends an endocrine or chemical signal instead of an electrical signal. MEMS innovations Microchips Biotech made several innovations in the microelectromechanical systems (MEMS) manufacturing process to ensure the microchips could be commercialized.
A major innovation was enabling final assembly of the microchips at room temperature with hermetic seals. Any intense heat during final assembly, with hermetic sealing, could destroy the drugs already loaded into the reservoirs
which meant common methods of welding and soldering were off-limits. To do so, Microchips Biotech modified a cold-welding ongue and grooveprocess.
This meant depositing a soft, gold alloy in patterns on the top of the chip to create tongues, and grooves on the base.
By pressing the top and base pieces together, the tongues fit into the grooves, and plastically deforms to weld the metal together. ach one of these reservoirs,
The company has also found ways to integrate electronics into the microchips to shrink down the device.
the company could refine the microchips to be even smaller, yet carry the same volume of drugs. his means making the drugs take up more volume than the electrical and other components,
