Mind Controls: Magnetic Relief For Depression

Anyone who remembers high-school physics knows that a fluctuating magnetic field can induce an electrical current. That's the principle behind transcranial magnetic stimulation (TMS), where an electromagnet is held over the head and pulsed rapidly. Depending on the frequency of the pulses, this can either enhance or… » 4/11/11 5:20pm 4/11/11 5:20pm

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

Gadget Lab got a hands-on demo with a prototype magnetic levitation haptic control unit at Carnegie Mellon University, where they experienced the artifical feel (via magnets) of 3d rabbits, hard surfaces and vinyl records. In addition to simulating the general shapes of objects, the technology can accurately reproduce… » 3/05/08 6:15pm 3/05/08 6:15pm
