Sodium-ion cathode Researchers at the University of Texas at Dallas and Seoul National University developed a manganese and sodium-ion-based cathode material they hope could lead to lower-cost rechargeable batteries. In a typical lithium-ion battery, the cathode is made of lithium, cobalt, nickel and oxygen. "Lithium is a more expensive, limited resource that must be mined from just a fe... » read more

3D chip integrates computing, storage Researchers at Stanford University and MIT developed a prototype 3D chip that integrates computation and data storage, based on carbon nanotubes and resistive RAM (RRAM) cells. The researchers integrated over 1 million RRAM cells and 2 million carbon nanotube FETs, making what the team says is the most complex nanoelectronic system ever made with emergi... » read more

Silicon nanosheet-based builds 5nm transistor To enable the manufacturing of 5nm chips, IBM, GLOBALFOUNDRIES, Samsung, and equipment suppliers have developed what they say is an industry-first process to build 5nm silicon nanosheet transistors. This development comes less than two years since developing a 7nm test node chip with 20 billion transistors. Now, they’ve paved the way for 30 billi... » read more

Probing photon-electron interactions According to Rice University researchers, where light and matter intersect, the world illuminates; where they interact so strongly that they become one, they illuminate a world of new physics. Here, the team is closing in on a way to create a new condensed matter state in which all the electrons in a material act as one by manipulating them with light and a... » read more

Connecting implanted devices University of Washington researchers developed a new method for communication between devices such as brain implants, contact lenses, credit cards and smaller wearable electronics with other devices such as smartphones and watches. Using only reflections, an interscatter system requires no specialized equipment, relying solely on mobile devices to generate Wi-... » read more

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

How nanocrystal structures self assemble Researchers at MIT and the Cornell High Energy Synchrotron Source (CHESS) have discovered some of the secrets to a long-hidden magic trick behind the self-assembly of nanocrystal structures, the understanding of which could be used to create more vivid display screens and optical sensory devices. The transformation of simple colloidal particles — b... » read more

Low power Wi-Fi Computer scientists and electrical engineers from the University of Washington came up with a way to generate Wi-Fi transmissions using 10,000 times less power than conventional methods and which consumes 1,000 times less power than existing energy-efficient wireless communication platforms such as Bluetooth Low Energy and Zigbee. The system, Passive Wi-Fi, uses backscatte... » read more

Cache-coherence innovation for thousand-core chips MIT researchers are getting ready to unveil what they say is the first fundamentally new approach to cache coherence in more than three decades. They reminded that in a modern, multicore chip, every processor core has its own small memory cache, where it stores frequently used data. The chip also has a larger, shared cache, which all the cores... » read more

Think IoT Designs Are Challenging? Try Embedded Systems In The Brain
By Brian Fuller - 13 Aug, 2015 - Comments: 0

There’s low power and then there’s low power. There are amazing applications and then there are amazing applications. Today the bleeding edge of low power design is not so much in IoT (although excellent work is being done in that space) but in medical, where the stakes are high and possible outcomes life-altering. Chet Moritz, associate professor with the University of Washington’s... » read more
