this was a good one. why? because it was so well explained. the article says a lot of things that are undeniably true. sound travels very well thru bone tissue for instance so this implant is possible from a pure audiological perspective. the only "big" problems with something like this is power supply and antenna, while antennas could probably fit in the neighbor molar or be implanted somewhere else, batteries aren't good enough to present a lasting good solution. you will need something that is both small, be able to hold a fair bit of juice and be extremely resilient to degradation with is a huge problem with NiMH cells and simmilar batteries. I don't know any battery techology which is good enough for something like this. If YOU do then please tell me.
i'd probably say no to an implant that allows the government to track me though. and oh yes, don't bother saying i'm paranoid m'kay?
