Is it going to implants? I will tell you that the current trend of smaller, cheaper, lighter will continue. We've gone from four pounds to an intermediate device that I didn't bring, which is two pounds, to the one I have here, which weighs around 12 ounces. These will continue to get smaller and smaller until we reach the point—just as we have with cellphones—where it doesn't make any sense to make them smaller.
The problem with an implant device is.... There was a company in south Florida that was selling an implant device, but it was really a device that was an RF tag and required an RF sensor to be very close to it. The problem is that you can't change physics. We have a signal in space that we have to be able to receive. We have an issue with the battery. I'm not particularly anxious to have a lithium ion battery implanted inside of me. Then there is the propagation required for communication.
So while we're not there yet, could it get to implants? Time will tell.
