Power/Performance Bits: Dec. 8


Light in lieu of wires In a development that could eventually lead to computers that use optics rather than electricity to carry data, Stanford engineers have designed and built a prism-like device they call an ‘optical link’ that can split a beam of light into different colors and bend the light at right angles. The optical link is a tiny slice of silicon etched with a pattern that res... » read more

Sound power While medical researchers would like to plant tiny electronic devices deep inside our bodies to monitor biological processes and deliver pinpoint therapies or relieve pain, so far engineers have been unable to make such devices small and useful enough. Providing power to the implants has been one stumbling block, and the use of wires or batteries to deliver power make implants ... » read more

Safety first A technology designed for conventional lithium-ion batteries by Stanford University researchers warns the user before it overheats and bursts into flames. The goal was to create an early-warning system to saves lives and property, by detecting problems that occur during the normal operation of a battery, the researchers said. The technology does not apply to batteries damaged i... » read more

The Missing Link


What continues to fascinate me about the IoT opportunity is the explosion of creative ideas that are being imagined and developed to enable the next big thing. When I imagine the kind of connectivity and control that will need to happen between the Internet and ‘smart’ devices, these things obviously must be very inexpensive, super small, with the ability to harvest their own energy. ... » read more

Phosphorus: a promising semiconductor According to researchers at Rice University, defects damage the ideal properties of many 2D materials, like carbon-based graphene, but phosphorus just shrugs, making it a promising candidate for nano-electronic applications that require stable properties. The team analyzed the properties of elemental bonds between semiconducting phosphorus atoms in 2D s... » read more

First transistor-based flexible device with graphene A flexible display incorporating graphene in its pixels’ electronics has been successfully demonstrated by the Cambridge Graphene Centre and Plastic Logic, the first time graphene has been used in a transistor-based flexible device. The prototype is meant to be a first step towards the wider implementation of graphene and graphene-like ... » read more

Popeye would be proud According to physicists at Purdue University, spinach holds the promise of being able to convert sunlight into a clean, efficient alternative fuel. The Purdue team is part of an international group using spinach to study the proteins involved in photosynthesis, the process by which plants convert the sun’s energy into carbohydrates used to power cellular processes. ... » read more

Cool Magnets MIT researchers believe that magnets on the outside of the refrigerator may someday be used for cooling. Magnons, which are essentially a collective spin wave or quasi-particle, are also conductors of heat. MIT researchers found that when exposed to a magnetic field gradient, magnons can be driven from one end of a magnet to another, carrying heat with them. “You can p... » read more

Lithium-free flexible battery A Rice University laboratory has flexible, portable and wearable electronics in its sights with the creation of a thin film for energy storage. The researchers have developed a flexible material with nanoporous nickel-fluoride electrodes layered around a solid electrolyte to deliver battery-like supercapacitor performance that combines the best qualities of a h... » read more

Making flexible carbon nanotube circuits more reliable and efficient Engineers would love to create flexible electronic devices, such as e-readers that could be folded to fit into a pocket with one such approach involving designing circuits based on electronic fibers known as carbon nanotubes (CNTs) instead of rigid silicon chips -- but reliability is essential. Given that most silicon chip... » read more
