Performance To The People
By Ed Sperling - 13 Jul, 2017 - Comments: 0

Ever since the IoT became a household term, the almost universal concept was that extremely low-power, simplistic devices would rule the edge. They would collect data, send it to the cloud, and the cloud would send back useful information. That's a great marketing concept for gateways and cloud services, but it's not scalable. Consumers don't just want to know when their heartbeat is irregul... » 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

Harvesting energy from multiple sources Researchers from the University of Oulu in Finland found a particular type of perovskite, KBNNO, has the right properties to extract energy from multiple sources simultaneously. While perovskites are particularly known for their use as solar cells, certain minerals in the perovskite family show piezoelectric and pyroelectric (harvesting energy from ... » read more

3D porous microsupercapacitors A research team from the King Abdullah University of Science and Technology (KAUST) developed an integrated microsupercapacitor targeted at self-powered system applications where the power source may be intermittent, such as sensors for wearables, security, and structural health monitoring. The key to the microsupercapacitors is vertically-scaled three-dimen... » read more

Architecting For Energy
By Ann Mutschler - 10 Nov, 2016 - Comments: 0

Most of the time, electrical design engineers create their designs by putting in the functions first, then going back later to figure out what they can afford to shut down. But with energy harvesting, this is flipped, and the systems must be built to normally be ‘off,’ and with a clear understanding of the minimum power requirements. Also, most of the time, energy harvesting systems are ... » read more

Energy Harvesting Gains Steam
By Ann Mutschler - 10 Nov, 2016 - Comments: 0

Energy harvesting is gaining traction with a surge in ultra-low-power IoT applications, ranging from inventory tracking, wearables and drones, to vibration sensors for motors in industrial settings. The idea that machines could run without batteries—or that energy could be harvested either from motion or ambient sound waves or chemical reactions to augment battery power—has been in the w... » read more

Energy-harvesting floor Engineers at the University of Wisconsin-Madison developed a flooring material which can be used as a triboelectric nanogenerator to convert footsteps into electricity. The method uses wood pulp, a common waste material already often used in flooring. The pulp is partly make of cellulose nanofibers, which when chemically treated produce an electrical charge when th... » read more

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

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…)
By Mike Gianfagna - 30 Jun, 2016 - Comments: 0

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
