Technique unlocks graphene for semiconductors
To truly be useful, graphene would need to carry an electric current that switches on and off, as silicon does in the form of billions of transistors on a computer chip.
Spider silk could be used as robotic muscle
Spider silk, already known as one of the strongest materials for its weight, turns out to have another unusual property that might lead to new kinds of artificial muscles or robotic actuators, researchers have found.
Electronic skin glows when it gets hurt
Electronic-skin technologies for prosthetics and robots can detect the slightest touch or breeze. But oddly, the sensors that make this possible do not respond effectively to a harmful blow.
Crumpled graphene could provide an unconventional energy storage
Researchers have now found that crumpling a piece of graphene "paper" — a material formed by bonding together layers of the two-dimensional form of carbon — can actually yield new properties that could be useful for creating extremely stretchable supercapacitors to store energy for flexible electronic devices.
