An international team of researchers has invented new artificial muscles strong enough to rotate objects a thousand times their own weight, but with the same flexibility of an elephant's trunk or octopus limbs.

Engineers have developed a new type of microchip muscle stimulator implant that will enable people with paraplegia to exercise their paralyzed leg muscles.
It is the first time that researchers have developed a device of this kind that is small enough to be implanted into the spinal canal and incorporates the electrodes and muscle stimulator in one unit. The implant is the size of a child's fingernail.

 | A multidisciplinary team of researchers from UCLA, UC Merced, the Pennsylvania State University, Northwestern University, and Japan have observed single-molecule interactions of rotaxanes functioning in their native environment. The team, in research published in the journal ACS Nano, developed a molecular design that firmly attached rotaxanes to a surface, enabling them to be individually examined in their native environment by a scanning tunneling microscope. ...> Full Article |
Using neutron beams and atomic-force microscopes, a team of university researchers working with the National Institute of Standards and Technology may have resolved a 10-year-old question about an exotic class of "artificial muscles" -- how do they work? Their results could influence the design of future specialized robotic tools.

 | Surgeons from UC Davis Medical Center have demonstrated that artificial muscles can restore the ability of patients with facial paralysis to blink, a development that could benefit the thousands of people each year who no longer are able to close their eyelids due to combat-related injuries, stroke, nerve injury or facial surgery. ...> Full Article |
 | BioInterfaces represents an ambitious new "Key Technologies" research program supported by the Helmholtz Association, the largest German scientific funding organization. The program brings together a team of biologists, chemists, physicists, materials scientists and informaticians. With an annual budget of approximately 20 million euro ($27.6 million), the 67 research teams will work closely together to develop innovative tools and technologies for precisely controlling the behavior of cells. ...> Full Article |
Soft and tough like biological tissue: DNA-wrapped carbon nanotubes

Northwestern University researchers have shown that it could be possible to control a limb by stimulating groups of muscles rather than individual muscles -- a finding that could be useful in future treatments of paralysis patients. The research team used a model of the muscles in a frog's hind leg to perform a computational analysis that shows researchers can control the limb using muscle groups just about as well as if they controlled individual muscles.

Researchers have demonstrated for the first time that a direct artificial connection from the brain to muscles can restore voluntary movement in monkeys whose arms have been temporarily anesthetized.
