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

When Patrick McMullan wants a Diet Dr Pepper while he’s at work, he pays for it with a wave of his hand. McMullan has a microchip implanted between his thumb and forefinger, and the vending machine immediately deducts money from his account.

The chips he and his employees got are about the size of a very large grain of rice. They’re intended to make it a little easier to do things like get into the office, log on to computers, and buy food and drinks in the company cafeteria

chip includes identifying information to grant him access to the building, as well as some basic medical information,
