Transmitting brain signals to a computer wirelessly

Scientists at Brown University have made brain-machine interfaces that are even more hip that BMIs researchers are using now. Like an upgrade from landlines to cell phones, their new device can record and transmit brain signals to a computer wirelessly. Free from onerous connections and wires, the technology could foster the development of a new generation of more flexible robotics to help amputees, spinal cord injury victims, or people with crippling neurological disorders.

Referred to the researchers affectionately as the “can,” the titanium-enclosed devicemeasures 2.2 inches (56 mm) long, 1.65 inches (42 mm) wide, and 0.35 inches (9 mm) thick. That’s pretty small considering it contains an array of 100 electrodes, a lithium ion battery, and custom-designed ultralow-power integrated circuits, radio and infrared wireless transmitters, and a copper coil for recharging. The battery lasts up to seven hours before it needs recharging. When it is time to recharge, power is transferred to the battery wirelessly through the skin…>>>more

    Hello, i think that i saw you visited my weblog so i came to
    “return the favor”.I am attempting to find things to improve
    my website!I suppose its ok to use a few of your ideas!
