1-ultralowpowe

by Larry Hardesty @ phys.org

The latest buzz in the information technology industry regards “the Internet of things”—the idea that vehicles, appliances, civil-engineering structures, manufacturing equipment, and even livestock would have their own embedded sensors that report information directly to networked servers, aiding with maintenance and the coordination of tasks.

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, even at the extremely low power levels characteristic of tiny solar cells. Previous experimental ultralow-power converters had efficiencies of only 40 or 50 percent.

by Graham Prophet @ edn-europe.com:

An alliance led by IBM Research, together with New York academic institution SUNY Polytech and with Samsung and GlobalFoundries, has produced 7nm (nanometer) node test chips with functioning transistors.

Continuing semiconductor scaling down to feature sizes of 7 nm is expected to yield further gains in performance, and lower power levels, but in IBM’s words, “[its] researchers had to bypass conventional semiconductor manufacturing approaches”. The finFET-style transistors in the demonstrator were constructed with silicon-germanium (SiGe) channels, and the lithography that defined them employed Extreme Ultraviolet (EUV) technology, “at multiple levels”. [That is, the use of EUV was not reserved for definition of a single critical part of the transistor structure.]

Flexible electronics specialist FlexEnable says it has made a technology breakthrough which makes the manufacture of glass free LCDs practical and cost effective. Supporting the development, the company will demonstrate a full colour conformal in plane switching organic LCD at the forthcoming SID event in San Jose. It adds the display is light, thin and robust.

transient-electronic-heat

by Darren Quick @ gizmag.com:

Expanding on previous research into electronic devices that dissolve in water once they have reached the end of their useful life, researchers at the University of Illinois have developed a new type of “transient” electronic device that self-destructs in response to heat exposure. The work is aimed at making it easy for materials from devices that usually end up in landfill to be recycled or dissolved completely.

The research involved a group led by aerospace engineering professor Scott R. White teaming up with John A. Rogers, who previously led work in the development of transient electronics that biodegrade in water. These previous devices dissolved in water after a predetermined period of time, which was related to the thickness of outer protective layers encapsulating the actual electronics. But using heat as a trigger has now enabled the creation of electronic devices that can be prompted to self-destruct on demand.

PORTLAND, Ore. — The world’s most expensive semiconductor fabrication plant–at over $14 billion–was announced at the ground breaking ceremony Thursday (May 7) by Samsung. Located in the Godeok Industrial Complex at Pyeongtaek City Gyeonggi-do Province–called “Samsung Semiconductor Valley”–in South Korea, Samsung will be building 10-nanometer FinFET semiconductors there.

transparent-solar-cell

by Amy Norcross @ edn.com:

A team of Michigan State University (MSU) researchers has created a transparent solar concentrator able to turn any window (or other sheet of glass, such as the screen for a smartphone) into a photovoltaic solar cell. What makes this development different? The panel is truly transparent.

Earlier attempts at building transparent solar cells resulted in panels with tinted glass and/or compromised visibility. Lead researcher Richard Lunt, an assistant professor of chemical engineering and materials science at MSU, says, “No one wants to sit behind colored glass. It makes for a very colorful environment, like working in a disco.”

by Martin Cooke @ elektor.com:

A team of researchers at the University of California, Los Angeles have designed a relatively low-cost smartphone add-on device that turns it into a mobile DNA imaging tool. Techniques using optical microscopy have found numerous applications in biology, chemistry and physics but they require relatively expensive, bulky and complicated instruments that cannot be easily transported outside the lab environment

The team have developed a compact, lightweight and cost-effective fluorescence microscope which clips onto a mobile phone and makes use of its built-in camera. Using the device they have demonstrated imaging and length quantification of single molecule DNA strands.

ChiplessBarcodes

A new generation of chipless RFID tags could soon be set to replace standard product barcodes. A research team at Monash University led by Dr Nemai Karmakar, from the Department of Electrical and Computer Systems Engineering, have been developing chipless radio frequency identification (RFID) tags that can be printed directly onto products and packaging – including postal items, drugs and books – potentially making this new technology cheaper, smaller and faster than any other tracking system on the market.

The team have succeeded in producing fully printable tags for products made of metal and containing liquids including water bottles and soft-drinks cans. Until now, this hasn’t been possible because metal and liquids interfere with the technology. The tag can be printed using an inkjet printer and read when they are attached to reflective surfaces such as metal cans and water bottles.

Michigan Micro Mote (M3) is the world’s smallest computer. How small? It’s about the size of a grain of rice. A University of Michigan’s March report can tell you that the team behind the computer have come up with a fully autonomous system that can act as a smart sensing system. “To be ‘complete,’ a computer system must have an input of data, the ability to process that data – meaning process and store it, make decisions about what to do next – and ultimately, the ability to output the data,” said David Blaauw, one of the faculty members who achieved the Michigan Micro Mote.
