Technology science wireless implants brain-computer interface

-
Researchers at Brown University have succeeded in creating the first wireless, implantable, rechargeable, long-term brain-computer interface. The wireless BCIs have been implanted in pigs and monkeys for over 13 months without issue, and human subjects are next.
-
Brown’s wireless BCI allows the subject to move freely, dramatically increasing the quantity and quality of data that can be gathered — instead of watching what happens when a monkey moves its arm, scientists can now analyze its brain activity during complex activity, such as foraging or social interaction

the device’s power consumption, which is just 100 milliwatts. For a device that might eventually find its way into humans, frugal power consumption is a key factor that will enable all-day, highly mobile usage

Amusingly, though, the research paper notes that the wireless charging does cause significant warming of the device

While the wireless BCI isn’t approve for human use (and there’s no indication that they’re seeking approval yet), it was designed specifically so that it should be safe for human use.
