Carbon nanotubes used to create conducting fibers for artificial muscles

By - July 24, 2015 2 Pictures

A new kind of conducting fiber developed at the University of Texas at Dallas is being used to develop artificial muscles and capacitors that store more energy when stretched. The fiber, which is composed of carbon nanotube sheets wrapped around a rubber core, may one day also find use in morphing aircraft, stretchy charger cords and exoskeleton limbs, along with connecting cables for a wealth of other devices.

Needle-sized mechanical wrist gives surgery a new angle

By - July 24, 2015 2 Pictures

Some of the most difficult types of surgery just got easier and more versatile. A team of engineers and doctors at Vanderbilt University has developed a tiny mechanical wrist that can be used for millimeter-sized incisions and sutures that allow new kinds of operations and less-invasive ways of conducting existing procedures. The wrist is flexible enough that its end can be steered to allow needles to reach inside the nose, throat, ears, urethra, and brain.
