Folding robots: No battery, no wire, no problem

Wed, 2017-07-19 23:39
Folding robots based on origami have emerged as an exciting new frontier of robotic design, but generally require onboard batteries or a wired connection to a power source, limiting their functionality. Scientist have now created battery-free folding robots that are capable of complex, repeatable movements powered and controlled through a wireless magnetic field.

Breathable, wearable electronics on skin for long-term health monitoring

Mon, 2017-07-17 20:35
A hypoallergenic electronic sensor can be worn on the skin continuously for a week without discomfort, and is so light and thin that users forget they even have it on, says a Japanese group of scientists. The elastic electrode constructed of breathable nanoscale meshes holds promise for the development of noninvasive e-skin devices that can monitor a person's health continuously over a long period.

Fluorine grants white graphene new powers

Fri, 2017-07-14 23:34
Fluorination of hexagonal boron nitride, a common insulator, turns it into a magnetic semiconductor. That may make the heat-resistant material suitable for electronics and sensors in extreme environments.

Researchers develop technique to control and measure electron spin voltage

Fri, 2017-07-14 01:20
Information technologies of the future will likely use electron spin -- rather than electron charge -- to carry information. But first, scientists need to better understand how to control spin and learn to build the spin equivalent of electronic components and tools. Now, researchers have developed a technique to control and measure spin voltage, known as spin chemical potential.

Researchers develop dynamic templates critical to printable electronics technology

Thu, 2017-07-13 17:45
When it comes to efficiency, sometimes it helps to look to Mother Nature for advice -- even in technology as advanced as printable, flexible electronics. Researchers have developed bio-inspired dynamic templates used to manufacture organic semiconductor materials that produce printable electronics. It uses a process similar to biomineralization -- the way that bones and teeth form.

Low-cost smart glove translates American sign language alphabet and controls virtual objects

Thu, 2017-07-13 05:42
Engineers have developed a smart glove that wirelessly translates the American Sign Language alphabet into text and controls a virtual hand to mimic sign language gestures. The device, which engineers call “The Language of Glove,” was built using stretchable and printable electronics that are inexpensive, commercially available and easy to assemble.

Signature analysis of single molecules using their noise signals

Wed, 2017-07-12 20:34
Unique noise signatures have been obtained from single molecules interacting with carbon nanotube-based electronic devices.

Harmless elements can replace toxic lead in electronics

Wed, 2017-07-12 17:13
Most smartphones and other electrical or electronic products contain small amounts of lead, which doesn’t sound like a big problem on its own. But when there are many billions of such products, either in daily use or gone astray, the total sums up to very large amounts of lead – which is a toxic heavy metal.

Thinking thin brings new layering and thermal abilities to the semiconductor industry

Tue, 2017-07-11 20:54
The concept of a simple technique to remove thin layers from otherwise thick, rigid semiconductor crystals has been actively explored for years. In a significant advance, a research group has successfully applied their new 'controlled spalling' layer transfer technique to gallium nitride (GaN) crystals, a prevalent semiconductor material, and created a pathway for producing many layers from a single substrate.

Brain-computer interfaces revolutionized using silicon electronics

Mon, 2017-07-10 22:01
An implanted brain-interface device could transform the lives of people with neurodegenerative diseases or people who are hearing and visually impaired, suggest researchers.

Mon, 2017-07-10 18:51
It's ultra-thin, electrically conducting at the edge and highly insulating within – and all that at room temperature. Physicists have developed a promising new material.

First battery-free cellphone makes calls by harvesting ambient power

Thu, 2017-07-06 02:14
Engineers have designed the first battery-free cellphone that can send and receive calls using only a few microwatts of power, which it harvests from ambient radio signals or light. It's a major step forward in moving beyond chargers, cords and dying phones.

Spinning around: A room temperature field-effect transistor using graphene's electron spin

Wed, 2017-07-05 22:01
A graphene-based spin field-effect transistor has been used in an operating at room temperature. Using the spin of the electrons in graphene and other layered material heterostructures the researchers have produced working devices as a step towards integrating spintronic logic and memory devices.

Printed electronic transistor circuits and displays, in which the colour of individual pixels can be changed, are two of many applications of ground-breaking research.

'Near-zero-power' temperature sensor could make wearables, smart devices less power-hungry

Wed, 2017-07-05 20:10
Electrical engineers have developed a temperature sensor that runs on only 113 picowatts of power -- 628 times lower power than the state of the art and about 10 billion times smaller than a watt. This near-zero-power temperature sensor could extend the battery life of wearable or implantable devices that monitor body temperature, smart home monitoring systems, Internet of Things devices and environmental monitoring systems.

The comeback kid: Black phosphorus and its new potential

Wed, 2017-07-05 19:23
When it was discovered over a century ago, black phosphorus was considered relatively useless. Over the past five years, however, the engineers and chemists have become intrigued by the material for its potential as an ultra-thin semiconductor, possibly ushering in a new age of flexible and smaller electronics. Now, one group reports that some commonly held assumptions about black phosphorus are incorrect and that the material is exceptionally tunable.

Molecular electronics scientists shatter 'impossible' record of rectification rate
