Wireless, Implantable Brain-Computer Interface Are In It's Animal Testing Phase Now

Researchers from Brown University have developed a wireless, implantable brain computer interface (BCI). If the trials are successful in monkeys and pigs, humans will be next for test phases.
The new BCI doesn't have to be attached to a computer, and the wearer can actually move around freely. BCIs are used to aid people who are paralyzed or have diminished motor functions by connecting them to control things like a robotic arm.
The device looks a lot like a pacemaker, with a li-lion battery, an inductive charging loop. It's got a chip that will digitize brain information, and an antenna that will transmit that info to a computer. According to Extreme Tech:
The BCI is connected to a small chip with 100 electrodes protruding from it, which, in this study, was embedded in the somatosensory cortex or motor cortex. These 100 electrodes produce a lot of data, which the BCI transmits at 24Mbps over the 3.2 and 3.8GHz bands to a receiver that is one meter away.
Here's an important invention we should all take note off: microwavable spray cake batter. Two college students invented the easiest and most effortless way to bake. All you have to do is spray the batter out of the cake into a dish and cook. Or microwave it. Brilliant: Read more
