Wearable sensors reveal health data from sweat In the name of science, UC Berkeley researchers want you to break out into a sweat — so it can be analyzed, of course. Specifically, the researchers have created a flexible sensor system that can measure metabolites and electrolytes in sweat, calibrate the data based upon skin temperature and sync the results in real time to a smartphone. The... » read more

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

Precisely controlling graphene molecules Researchers at UCLA’s California NanoSystems Institute have found that in the same way gardeners may use sheets of plastic with strategically placed holes to allow plants to grow but keep weeds from taking root, the same basic approach can be applied in terms of placing molecules in the specific patterns they need within tiny nanoelectronic devices, w... » read more

Electromagnetic properties of graphene-boron nitride materials Rice University and Montreal Polytechnic researchers reported that developing novel materials from the atoms up goes faster when some of the trial and error is eliminated. The work aims to simplify development of certain exotic materials for next-generation electronics. Specifically, Rouzbeh Shahsavari, a Rice materials scient... » read more

Wearing your batteries In spite of the progress in wearable devices, one challenge remaining is providing less obtrusive and cumbersome power sources. To tackle the problem, researchers at Case Western Reserve University developed flexible wire-shaped microsupercapacitors that can be woven into a jacket, shirt or dress. "The area of clothing is fixed, so to generate the power density need... » read more

Can Nano-Patterning Save Moore’s Law?


For years the academic community has explored a novel technology called selective deposition. Then, more than a year ago, Intel spearheaded an effort to bring the technology from the lab to the fab at 7nm or 5nm. Today, selective deposition is still in R&D, but it is gaining momentum in the industry. With R&D funding from Intel and others, selective deposition, sometimes called ALD-e... » read more

Singing to your storage Existing research on 'racetrack memory', which uses tiny magnetic wires, each one hundreds of times thinner than a human hair, down which magnetic bits of data run like racing cars around a track, has focused on using either magnetic fields or electric currents to move the data bits down the wires. However, both these options create heat and reduce power efficiency. ... » read more

A Semiconductor Approach To Desalination


By Bernard Murphy and Jim Hogan We’re not offering breaking news when we observe that the semiconductor industry is in flux. Major consolidations and lack of funding for startups point to an industry that, outside China, is maturing and seems to have lost the recipe for rapid growth. Apologists will argue that analog or MEMS or some other domains are still strong, but this misses the point... » read more

Lithium-air batteries gain ground Scientists at the University of Cambridge have developed a working laboratory demonstration of a lithium-oxygen battery which has very high energy density, is more than 90% efficient, and can be recharged more than 2000 times. Their demonstrator relies on a highly porous, 'fluffy' carbon electrode made from graphene (comprising one-atom-thick sheets of ca... » read more

Searching for energy-efficient architectures A workshop jointly funded by the Semiconductor Research Corporation (SRC) and National Science Foundation (NSF) sought out the key factors limiting progress in computing – particularly related to energy consumption – and novel research that could overcome these barriers. The report focuses on the most promising research directions in the ex... » read more
