A better band-aid UC Berkeley engineers are working on a bandage that can detect bedsores before they are visible - while recovery from them is still possible. Leveraging flexible electronics advancements, the researchers collaborated with colleagues at UC San Francisco to create their “smart bandage” that uses electrical currents to detect early tissue damage from pressure ulcers as th... » read more

Symmetry in graphene growth According to Rice University researchers, what lies beneath growing islands of graphene is important to its properties. The team analyzed patterns of graphene – a single-atom-thick sheet of carbon – grown in a furnace via chemical vapor deposition and discovered that the geometric relationship between graphene and the substrate, the underlying material on whi... » read more

Data center architectures have seen very few radical changes since the commercial introduction of the [getentity id="22306" comment="IBM"] System/360 mainframe in 1964. There have been incremental improvements in speed and throughput over the years, with a move to a client/server model in the 1990s, but from a high level this is still an environment where data is processed and stored centrally ... » read more

Hi-tech pens The University of California at San Diego has developed a hi-tech ballpoint pen. Researchers have taken off-the-shelf ballpoint pens and filled them with bio inks. With so-called enzymatic-ink-based roller pens, users are able to draw biocatalytic sensors on a surface. [caption id="attachment_18297" align="alignleft" width="300"] Researchers draw sensors capable of detecting... » read more

A viable silicon substitute A new study by UC Berkeley, the University of Pennsylvania and the University of Illinois at Urbana-Champaign (UIUC) moves graphene a step closer to knocking silicon off as the dominant workhorse of the electronics industry. They reminded that while silicon is ubiquitous in semiconductors and integrated circuits, researchers have been eyeing graphene, a one-atom... » read more

Glimpsing pathway of sunlight to electricity According to University of Oregon and Lund University researchers, four pulses of laser light on nanoparticle photocells in a University of Oregon spectroscopy experiment have opened a window on how captured sunlight can be converted into electricity. The work, which the researchers expect could inspire devices with improved efficiency in solar e... » read more

High rise chip For decades, the mantra of the semiconductor industry has been ‘smaller, faster, cheaper.’ Stanford researchers are also adding ‘taller’ to the mix, and describing how to build high-rise chips that promise to leapfrog the performance of the single-story logic and memory chips on today's circuit cards. Stanford researchers said their approach would end the ‘logjams�... » read more

Smarter Cars, But How Smart?
By Ernest Worthman - 09 Dec, 2014 - Comments: 0

With the emergence of the Internet of Things, smart cars are beginning to garner more attention — the kind that comes with real R&D dollars, market development plans and cost analyses for future commercialization. Smart cars are different than connected cars, which are simply smartphones on wheels. Until now, the focus on intelligence in automobiles has largely been on driver assist and in... » read more
