Muscles act as metamaterials due to collective behavior, physicists show
New soft motor more closely resembles real muscles (w/ video)
Why mechanical tension causes some crystals to jump, while others crumble
Crystals are not as stationary as you might think. A crystal of an organometallic compound containing palladium, for example, downright jumps from a hotplate once it reaches certain temperature. An international ...
Gel-based audio speaker demonstrates capabilities of ionic conductors, long thought limited in application (w/ Video)
In a materials science laboratory at Harvard University, a transparent disk connected to a laptop fills the room with music—it's the "Morning" prelude from Peer Gynt, played on an ionic speaker.
Controlled crumpling of graphene forms artificial muscle
Duke University engineers are layering atom-thick lattices of carbon with polymers to create unique materials with a broad range of applications, including artificial muscles.
Wax-filled nanotech yarn behaves like powerful, super-strong muscle (w/ video)
New artificial muscles made from nanotech yarns and infused with paraffin wax can lift more than 100,000 times their own weight and generate 85 times more mechanical power during contraction than the same size natural muscle, ...
Jellyfish Robot Swims Like its Biological Counterpart
Replacing batteries may become a thing of the past, thanks to 'soft generators'
Battery technology hasn't kept pace with advancements in portable electronics, but the race is on to fix this. One revolutionary concept being pursued by a team of researchers in New Zealand involves creating ...
Carbon nanotube muscles generate giant twist for novel motors
New artificial muscles that twist like the trunk of an elephant, but provide a thousand times higher rotation per length, were announced on Oct. 13 for a publication in Science magazine by a team of resear ...
Flexing fingers for micro-robotics: Scientists create a powerful, microscale actuator
Researchers with the DOE's Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California, Berkeley, have developed an elegant and powerful new microscale actuator that can flex like ...
Cyborg beetles to be the US military's latest weapon (w/ Video)
Artificial muscle made of fishing line is 100 times stronger than yours
By taking simple sewing thread and fishing wire and giving it a twist, scientists have created artificial muscle that's 100 times stronger than human or animal sinew. The invention, described in the journal Science, could ...
Artificial muscle capable of 'remembering' movements developed
Researchers from the University of Cambridge have developed artificial muscles which can learn and recall specific movements, the first time that motion control and memory have been combined in a synthetic ...
Artificial heart to pump human waste into future robots
A new device capable of pumping human waste into the "engine room" of a self-sustaining robot has been created by a group of researchers from Bristol.
