Stretchable silicon could be next wave in electronics

December 16, 2005

University of Illinois at Urbana-Champaign researchers have developed a fully stretchable form of single-crystal silicon with micron-sized, wave-like geometries that can be used to build high-performance electronic devices on rubber substrates.

Functional, stretchable and bendable electronics could be used in applications such as sensors and drive electronics for integration into artificial muscles or biological tissues, structural monitors wrapped around aircraft wings, and conformable skins for integrated robotic sensors, said… read more

Stretchable Silicon Could Make Sports Apparel Smarter

Stretchable silicon electronics that offer the computing power of rigid chips could make their way into Reebok‘s athletic apparel in the coming years to monitor athletes’ health and performance during training and rehabilitation.

The electronics could be totally incorporated into the inside of a shirt, or into a decal placed directly on the skin, without the need for a casing. They could conform to the body, and their… read more

Stretchable Silicon May Inspire a New Wave of Electronics

June 14, 2007

Scientists have created a form of nanoscale silicon that is stretchable. The new material may help pave the way for a class of stretchable electronic devices, such as “smart” surgical gloves and personal health monitors, that are not possible to create using current technology and materials.

Stretchable Silicon Sensors Could Speed Up Heart Surgery

May 5, 2011

Stretchable silicon, a new surgical technology, uses hundreds of thousands of stretchable sensors embedded on the surface of a balloon catheter to map electrical problems in the heart, such as atrial fibrillation.

The technology was recently developed at MC10 Inc. and successfully tested on animals by John Rogers at the University of Illinois at Urbana-Champagne and colleagues.

Conventional balloon catheters… read more

Stretchable, bendable optical interconnections for body sensors and robotic skin

February 20, 2014


Belgian researchers say they have created the first optical circuit that uses interconnections that are stretchable as well as bendable.The technology has applications like wearable body sensors and robotic skin.

These new interconnections, made of a rubbery transparent material called PDMS (polydimethylsiloxane), guide light along their path even when stretched up to 30% and when bent around an object the diameter of a human finger.

Stretched neutrinos could span the universe

June 10, 2009

The most massive quantum-mechanical superpositions of three different mass-energy states of “relic” neutrinos produced by the big bang may have slowed down, stretching them across the universe as it expanded, according to calculations by George Fuller and Chad Kishimoto of the University of California, San Diego.

Stretching sensors may enable novel wearable electronics

May 15, 2011


A new stretching sensor that measures both pressure and stretch has been developed by researchers at the Fraunhofer Institute for Silicate Research ISC in Würzburg.

Made of  an elastomer material coated on both sides with flexible electrodes, the sensor is able to stretch to twice its area before tearing.

“The sensors could be used to design [a] smart safety system [for airbags] that can sense… read more

University of Michigan (UM) researchers have developed chains of self-assembling particles that could serve as electrically activated muscles that could move microbots (microscopic robots).

These microbots could come in handy in medicine, manufacturing, and other areas. But there are several challenges, like building the microbots and making them mobile.

For the mobile part, Michael Solomon, a UM professor of chemical engineering, and his group started with particles with… read more

Stretchy circuits promise elastic gadgets

March 28, 2008

University of Illinois at Urbana-Champaign researchers have made stretchable and flexible silicon and plastic integrated circuits that are just one crystal–1.5 microns–thick.

The circuits are designed so that the plastic, not the silicon, absorbs most of the stress when the chips are bent. Until now, integrated circuits have been limited by use of much thicker, brittle silicon wafers.

Strokable robot rabbit talks with touch

May 23, 2008

A pet robot developed at the University of British Columbia that communicates with humans only by touch is being used to probe the way haptics our emotional relationships.

Using pressure sensors, the Haptic Creature can detect the way it is touched or stroked. It can only respond with breathing movements of its body, inaudible purring vibrations, or by moving its ears.

But even those simple responses to touch… read more

Stroke Brain Fix

January 25, 2006

Brain researchers may have found a way to make stroke-damaged nerve cells re-grow.

They used an immune-system protein antibody to stop Nogo-A from binding to receptors on nerve cells. Without the inhibitory affect of Nogo-A, the injured nerve cells were able to re-grow, restoring lost movement to the front paws of the rats.

Neurologist Wendy Kartje from the Hines Veterans Administration Hospital in Illinois and her team was… read more

Stroke damage in mice overcome by training that ‘rewires’ brain centers

Study findings suggest physical and pharmacological solutions for human stroke victims
February 7, 2013


Mice can recover from physically debilitating strokes that damage the primary motor cortex, the region of the brain that controls most movement in the body if the mice are quickly subjected to physical conditioning that rapidly “rewires” a different part of the brain to take over lost function, Johns Hopkins researchers have found. The research uses precise, intense and early more

Stroke patients show signs of recovery in stem-cell treatment trial

May 29, 2013


Encouraging interim data from the world’s first clinical trial examining the safety of neural stem cell treatment in ischemic stroke patients has been reported by researchers ahead of an application for Phase II trials.

Professor Keith Muir of the University of Glasgow, who is heading the trial of ReNeuron Group plc’s ReN001 stem cell therapy at the Southern General Hospital, Glasgow reported that… read more

Stroke risk increased by sleeping less than six hours a night; simple eye test could detect

Habitually sleeping less than six hours a night predicts a significant increase in the risk of stroke symptoms, University of Alabama at Birmingham researchers found for middle-age to older adults of normal weight and at low risk for obstructive sleep apnea (OSA).

Their study followed 5,666 people for up to three years.

The participants had no history of stroke, transient ischemic attack, stroke symptoms or high risk for… read more

Strong Magnetism Creates Two-Dimensional Superconductivity

December 9, 2005

It should be possible to achieve stable superconductivity at higher temperatures by restricting electrons to two dimensions in space, University of Arizona physicist Andrei Lebed has shown.

Electrons will become completely two-dimensional within laboratory-produced magnetic fields that are between 200,000 times and a million times stronger (10 to 50 Tesla) than the magnetic field at the surface of the Earth, Lebed said.

In research published in the Dec.… read more
