Power/Performance Bits: June 4
By Jesse Allen - 04 Jun, 2019 - Comments: 0

Flexible high-temp dielectric Researchers at Rice University, Georgia Institute of Technology, and Cornell University developed a new high-temperature dielectric nanocomposite for flexible electronics, energy storage, and electric devices that combines one-dimensional polymer nanofibers and two-dimensional boron nitride nanosheets. The polymer nanofibers act as a structural reinforcement, w... » read more

Week in Review: IoT, Security, Auto

Internet of Things Dialog Semiconductor is shifting its product portfolio away from smartphones following its pending $600 million deal with Apple. The chip company is looking toward connected-health products and video-game consoles for future growth. The connected-health devices, developed in collaboration with pharmaceutical firms, would monitor blood pressure and check glucose levels, accor... » read more

In-Memory Computing Challenges Come Into Focus
By Katherine Derbyshire - 06 Feb, 2019 - Comments: 6

For the last several decades, gains in computing performance have come by processing larger volumes of data more quickly and with superior precision. Memory and storage space are measured in gigabytes and terabytes now, not kilobytes and megabytes. Processors operate on 64-bit rather than 8-bit chunks of data. And yet the semiconductor industry’s ability to create and collect high quality ... » read more

Fast rotors Purdue University and others have developed what researchers claim is the world’s fastest man-made rotor. Researchers devised a tiny dumbbell from silica. Then, the object was levitated in a vacuum using a laser, thereby creating a spinning effect. This, in turn, enabled more than 60 billion revolutions per minute or more than 100,000 times faster than a dental drill. The t... » read more

Tandem solar reaches 25.2% efficiency In the push for ever-more efficient solar panels, researchers are turning to tandem, or double-junction, photovoltaics. Tandem solar panels use two different types of solar cell capable of absorbing different wavelengths of light stacked on top of each other to maximize the conversion of light rays into electrical power. Recently, two groups have reache... » read more

What If We Had Bi-Directional RRAM?
By Katherine Derbyshire - 15 Feb, 2018 - Comments: 0

The ideal memristor device for neuromorphic computing would have linear and symmetric resistance behavior. Resistance would both increase and decrease gradually, allowing a direct correlation between the number of programming pulses and the resistance value. Real world RRAM devices, however, generally do not have these characteristics. In filamentary RRAM devices, the RESET operation can raise ... » read more

Energy-harvesting yarn Researchers at the University of Texas at Dallas and Hanyang University in South Korea developed a carbon nanotube yarn that generates electricity when stretched or twisted. Possible applications for the so-called "twistron" yarns include harvesting energy from the motion of ocean waves or from temperature fluctuations. When sewn into a shirt, these yarns served as a sel... » read more

China’s storage ring for EUV A group of researchers are banding together to propel the development of a storage ring technology that may one day be used as a power source for extreme ultraviolet (EUV) lithography. The collaboration includes five institutions. Researchers have organized an informal collaboration or study group with plans to develop a storage ring for EUV based on a techno... » read more

Materials For Future Electronics
By Katherine Derbyshire - 18 May, 2017 - Comments: 0

Examining the research underway in electronics materials provides a keyhole view into what may be possible in future electronics design. Although some of this research will not end up in commercial products, it does provide an indication of the kinds of problems that are being addressed, how they are being approached, and where the research dollars are being spent. Flexible electronics are a... » read more

Manufacturing Bits: Nov. 10
By Mark LaPedus - 10 Nov, 2015 - Comments: 1

Etching superconducting materials Superconductors are devices that have zero electrical resistance, making them attractive for a range of applications. But superconductors must be cooled down to temperatures at or near absolute zero on the Kelvin scale to work. This, in turn, limits their applications. Absolute zero equates to −273.15° on the Celsius scale and −459.67° on the Fahrenheit ... » read more
