WIRELESS TECHNOLOGY ---    NOVEL WIRELESS BRAIN SENSOR

In a significant advance for brain-computer interfaces, engineers have developed a novel wireless, broadband, rechargeable, fully implantable brain sensor that has performed well in animal models for more than a year.

This wireless system addresses a major need for the next step in providing a practical brain-computer interface," said neuroscientist John Donoghue, the Wriston Professor of Neuroscience at Brown University and director of the Brown Institute for Brain Science.

In the device, a pill-sized chip of electrodes implanted on the cortex sends signals through uniquely designed electrical connections into the device's laser-welded, hermetically sealed titanium "can." The can measures 2.2 inches (56 mm) long, 1.65 inches (42 mm) wide, and 0.35 inches (9 mm) thick. That small volume houses an entire signal processing system: a lithium ion battery, ultralow-power integrated circuits designed at Brown for signal processing and conversion, wireless radio and infrared transmitters, and a copper coil for recharging -- a "brain radio." All the wireless and charging signals pass through an electromagnetically transparent sapphire window.
