Strained Graphene Creates Pseudo-Magnetic Fields Stronger Than Any Before Seen

11:30PM July 31, 2010 | Rebecca Boyle - Pop Sci

Putting the right kind of strain on a patch of graphene can make super-strong pseudo-magnetic fields, a new study says. The finding sheds new light on the properties of electromagnetism, not to mention the odd properties of graphene. More »

Maglev Haptic Control Technology Could be Used for Microsurgery, Robot Control

10:15AM March 6, 2008 | Adrian Covert

Gadget Lab got a hands-on demo with prototype magnetic levitation haptic control unit at Carnegie Mellon University, where they got a simulated feel for 3D rabbits, hard surfaces and vinyl records. In addition to simulating the general shapes of objects, the technology can accurately reproduce qualities like texture and elasticity using an interesting dual joystick setup.

Embotec Magnet Keyboard Floats Keys

12:30AM July 28, 2007 | jenneth

Embotec has just revealed a new concept keyboard that breaks the mold of traditional typing devices, accepting the crush of our fingers with either a spring or rubber base. Instead, the Magnet Keyboard levitates the keys from the board, and regulates the levitation through electromagnetism. More »
