To sum up, bluetooth device is implanted under the skin and looks like a tattoo. It's touch-screen and runs on glucose in the blood being converted to oxygen and electricity. Or something like that.
My question is why they're only using it for phone stuff, and when I can have one (it's still just a concept). ..and also if it's for real.
Phone keypads are troublesome enough without being a part of your arm. Can you imagine accidentally hitting your mom's speeddial during sex, or something?
Kosmopolit, my guess would be that you'd have to remove it in order to get it fixed. If it's powered by biological systems, the only thing I can see going wrong is the actual hardware breaking, but I suppose they'd have accounted for that sort of thing and made it both flexible (an absolute must for the location they'll probably put it in) and durable. Still, it looks like the surface of the device is bumpy and so is designed to have your skin and tissues basically adopt it. While this is the best thing if you want the implant to stay in permanantly, it could be a major pain in the ass for any mechanical repairs.
Or who knows, maybe they'll have mini blood robots that'll fix it.
What about degredation? wonder what the life span of it would be, and it says "other Bluetooth devices - both in the outside world and within the same body" the possibilities of that are huge.
This will no doubt be another phone that I fall on and break. What about diabetics? When their blood sugar drops does the phone stop working? This would be tragic in particular for diabetics running from some sort of movie monster as they would be unlikely to have some candy on them and would be unable to call in for backup.
I think I will wait until I can implant some sort of particle beam into my arm and save the arm mounted phones for my shirt sleeves.
I would think that if it's burning glucose the same function that now tells you that the battery is low could alert you of your low blood sugar or even auto-dial for help.
As to degradation, I have no idea what materials they're using, but the screws that I've had put in me are still just fine after years and years..
