Darpa develops brain chip that collects electrical signals and sends them to a computer

Australian scientists funded by the US Defense Advanced Research Projects Agency (Darpa) have developed a transmitter device that can be injected into the brain without invasive surgery and then used to collect electrical signals and then send the data to a computer for analysis, which is a breakthrough in making brain machine interfaces possible.

 

Researchers from the University of Melbourne have invented the stentrode – a device the size of a paper clip that is basically a tiny stent that comes with an array of electrodes. At the moment, the only way to put electrodes into the brain is to open up the skull during surgery. Instead, the stentrode is flexible enough to be able to pass through the brain via curving blood vessels, yet stiff enough to work properly once it arrives at its destination.
