Energy-harvesting shirt Engineers at the University of California San Diego developed a 'wearable microgrid' that harvests and stores energy from the human body to power small electronics. The microgrid consists of three main parts: sweat-powered biofuel cells, motion-powered triboelectric generators, and energy-storing supercapacitors. All parts are flexible, washable and can be screen pri... » read more

Undoped polymer ink Researchers at Linköping University, Chalmers University of Technology, University of Washington, University of Cologne, Chiba University, and Yunnan University developed an organic ink for printable electronics that doesn't need to be doped for good conductivity. "We normally dope our organic polymers to improve their conductivity and the device performance. The proces... » read more

Optimizing fiber networks Researchers at Chalmers University of Technology are working towards reducing the energy consumption of fiber optic communications before the amount of electricity required by the Internet becomes too great to manage. To improve overall efficiency, the team tackled several aspects of fiber optic cables. One of the major energy drains the team identified was the err... » read more

Jumping the gap in microchips A quasi-particle that travels along the interface of a metal and dielectric material may be the solution to problems caused by shrinking electronic components, according to an international team of engineers. "Microelectronic chips are ubiquitous today," said Akhlesh Lakhtakia, Evan Pugh University Professor and Charles Godfrey Binder Professor of Engineering S... » read more

Image-recognizing glass Engineers at the University of Wisconsin-Madison, MIT, and Columbia University developed a way to create 'smart' glass capable of performing image recognition tasks without the need for electronics or power. "We're using optics to condense the normal setup of cameras, sensors and deep neural networks into a single piece of thin glass," said Zongfu Yu, electrical and ... » read more

Future batteries could use a graphene sponge Researchers at Sweden’s Chalmers University of Technology devised a porous, sponge-like aerogel, made of reduced-graphene oxide, to serve as a freestanding electrode in the battery cell. This utilization has the potential to advance lithium sulfur batteries, which are said to possess a theoretical energy density about five times greater than lithi... » read more

Long-term solar energy storage Researchers from Chalmers University of Technology and Universidad de La Rioja created a system capable of storing solar energy for extended periods of time. The system, called Molecular Solar Thermal Energy Storage (MOST), hinges on a molecular photoswitch made from carbon, hydrogen and nitrogen. When the molecule is hit by sunlight, it turns into an energy-rich... » read more

An evolution in electronics Restoring some semblance to those who have lost the sensation of touch has been a driving force behind Stanford University chemical engineer Zhenan Bao’s decades-long quest to create stretchable, electronically-sensitive synthetic materials. [caption id="attachment_24131783" align="aligncenter" width="300"] Zhenan Bao, the K.K. Lee professor of chemical engineer... » read more

Ad hoc "cache hierarchies" Researchers at MIT and Carnegie Mellon University designed a system that reallocates cache access on the fly, to create new "cache hierarchies" tailored to the needs of particular programs. Dubbed Jenga, the system distinguishes between the physical locations of the separate memory banks that make up the shared cache. For each core, Jenga knows how long it would t... » read more
