>It’s also huge, since it comes with a battery pack that charges wirelessly. This is one of the main problems with sub-dermal implants. You don't want anything trans-dermal, because it's a recipe for infection. But if it's sub-dermal, it not only needs to be biocompatible but also needs to wirelessly transmit data. This implies a need for a power source of some sort that won't overheat. I sincerely hope he's thought this through, because if that battery gets too hot, he's going to destroy a lot of tissue, to say nothing of how biocompatible the device is.
