Power/Performance Bits: Sept. 20

Energy-harvesting fabric Researchers at the Georgia Institute of Technology and Chongqing University in China developed a fabric that can simultaneously harvest energy from both sunshine and motion. The fabric, just .32mm thick, was constructed using a commercial textile machine to weave together solar cells constructed from lightweight polymer fibers with fiber-based triboelectric nanoge... » read more

Power/Performance Bits: Sept. 13

Core-to-core communication Most research featured in the Power/Performance Bits has far-off applications, but a team from North Carolina State University and Intel developed something that could be brought into practice today: a way to accelerate core-to-core communication. Many important workloads incur significant core-to-core communication and are affected significantly by the costs, i... » read more

Power To The People (Right On…)

If you’re the right age (or older), you will immediately think of John Lennon when you read the title of this piece.  The song was released in 1971, so I will cut many of you some slack on that. The title was inspired by several pieces of research that I was fortunate enough to be exposed to this past week. I am currently in Vancouver, British Columbia at the NEWCAS conference. NEWCAS... » read more

Power/Performance Bits: April 12

Digital storage in DNA Computer scientists and electrical engineers from University of Washington and Microsoft detailed one of the first complete systems to encode, store and retrieve digital data using DNA molecules, which can store information millions of times more compactly than current archival technologies. Progress in DNA storage has been rapid: in 1999, the state-of-the-art in DN... » read more

Power/Performance Bits: Feb. 16

Energy storage on microchips After more than half a decade of speculation, fabrication, modeling and testing, an international team of researchers from Drexel University in Pennsylvania and Paul Sabatier University in Toulouse, France, confirmed that their process for making carbon films and micro-supercapacitors will allow microchips and their power sources to become one and the same. Si... » read more

Power/Performance Bits: Feb. 2

Single electron transistors A group coordinated by the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) is setting out on a four year program to develop single electron transistors fully compatible with CMOS technology and capable of room temperature operation. The single electron transistor (SET) switches electricity by means of a single electron. The SET is based on a quantum dot (consisting... » read more

Blog Review: Jan. 13

Is it time for one of the Seven Wonders to return? In this week's top engineering and tech picks, Ansys' Justin Nescott highlights a project to rebuild the Colossus of Rhodes. Plus, new tech for cars and a hoodie for taking naps. From CES, Rambus' Aharon Etengoff expands on a talk about intelligent transportation systems and the need to balance technology which could help reduce accidents wi... » read more

Keeping The Lights On

IoT is comprised of numerous industries. For the sake of analysis, these can be segmented into several tiers that function as independent networks or integrated complicated meshes. In my November post I examined the three-tier IoT architecture at a high level. Then last month I focused on the rapidly expanding market of intelligent gateways. Gateways receive information from cloud applicatio... » read more

Power/Performance Bits: Dec. 23

GaN building blocks A team of engineers from Cornell University, the University of Notre Dame, and the semiconductor company IQE created gallium nitride (GaN) power diodes capable of serving as the building blocks for future GaN power switches. In spite of having many desirable features as a material, GaN is notorious for its defects and reliability issues. So the team zeroed in on device... » read more

New Options For Power

Chipmakers have been talking for years about the next big breakthrough in battery technology, low-power architectures and energy harvesting. So far, none of them has made their job any easier. Batteries empty out too quickly, and the technology for improving the amount of energy that can be stored don't improve fast enough—or safely enough when they do show big improvements—to make a big... » read more
