Stretchy Wires to Create Artificial Nerves 138
Roland Piquepaille writes "Researchers from the Johns Hopkins University have built electronic circuits which exhibit a rubbery behavior. The flexible circuits, built by using gold springs, can stretch like rubber. And Nature says that these stretchy wires can be used to create artificial nerves bending inside our bodies or wearable electronics. 'Wiring like this could be woven into stretchy sports clothing and used to connect up sensors that monitor athletic performance. Rubbery electrodes made from biocompatible materials might be attached to a beating heart and used to sense impending problems.' This overview contains more details and references about these flexible wires."

But the research in the end use a polymer which I assume would have to be rubbery in order to strech with the spring.
" Instead of fashioning the gold wires into helical springs, however, they gave them a flat, oscillating shape, like a meandering river, since this is easier to make. They manufactured them by electroplating gold onto a sheet of silver, surrounding the wires with polymer and then stripping the silver away."
Admittedly metal particles and metal wires are slightly different but a wire is simply a structure made up of particles.

Most devices/machines today depend heavily on a motors/engines/circuits that are not usually flexible and need to maintain a rigid structure. Sure, we try to cover/encapsulate these devices in a pleasing exterior (car bodies, plastic casings etc) in order to protect the hardware and us from the dangerous interiors.
Imagine cars made up of soft cushiony/rubbery material, which bounces back to absorb a collision...the metal body can dent in and absorb the force of the impact, but it works only against collisions against other cars/hard objects -- not against collisions with humans/animals and other "soft" substances.
Ofcourse, we could have a soft covering for cars, made of a cushiony substance, but the problem has been embedding circuits/machinery in the soft exteriors, because they tend to bend and damage the interiors.
Nature has found the perfect way to create organs/pumps/filters/wires which are made out of soft tissue, and is malleable enough to survive severe tension/distortion and bending.
Here's to hoping that one day we will be able to create soft fuzzy machines which won't be so hard on our water-bag bodies.

I'd love to see experiments done where volunteers wear clothing (shoes, hats, socks, pants, underwear, shirts) with this type of thing embedded to collect data. This could be SO useful...
* Wear and tear points in clothing. Wear do different clothing styles rub against someone, potentially uncomfortably, depending on the body shape and size.
* hot/cold comfort... Where does the wearer get hotter, colder based on wear of certain overcoats, garments and standard clothing
* posture studies... how do people really sit, stand, skip and run? once again, by body shape, age, race, culture, locale
* interaction studies... check for nervousness and pulse rate and the like based on social interaction. This could be done with wires and straps and such, but those things also impose tehmselves on wearers. THis could be done "on the sly" like the driving studies about how much people pay attention, when they THINK it's about seeing how they react to traffic and road conditions.

"the researchers estimate that the wires should be able to withstand several thousand cycles of extension and contraction."
That's no where NEAR what would be needed for any of the applications they mention. For example, at 70 beats per minute your heart beats 100,800 times per day. Assuming each step a runner takes covers 3 feet (very approximate here), then a "cycle" (back to starting configuration) is 6 ft. That's 880 "cycles" per mile. A single 6 mile run is therefore over 5000 cycles.
Several thousand "cycles of extension and contraction" is not even close to enough for any real world app. Who wants to have that internal heart monitor replaced several times each day? How about that high-tech single use "smart" sweatshirt?
These will need to be in the 100's of thousands to millions of cycles for their lifespan before they have any real utility.

Small deformations just cause the atoms in the gold (or any other material) to get closer or further apart. This is elastic deformation and can be done about infinity + 1 times before the metal breaks. eg: you can slightly flex a paper clip until doomsday and it is largely unaffected.
Larger deformations actually cause the atoms to start moving around, changing places in the atomic lattice structure to accomodate the strain. This is primarily accomplished by the movement of defects and dislocations through the material. This is plastic deformation and each plastic deformation lowers the lifetime of the material. eg: if you take a paper clip and start seriously bending it, in a few cycles, the part you're bending breaks off.
I have no idea what the threshhold is between plastic and elastic deformation in these wires is but it should be possible to design devices where the flex wires are in the elastic deformation regime most of the time. Eg: a smart shirt would have flex wires designed to be in the elastic regime when you're skipping around, swinging your arms, whistling show tunes. However, when you trip over a comatose mime and fall into an open storm serwer, the wires would be plastically deformed but won't break like conventional electrodes would in the same situation. Thus giving us essential data to force passage of the mime prevention act of 2008.
