In time we wouldn't need any cellphone, bacause i discovered a time ago that our bones and our nerves will do service as a sender and recipient for cell phone frequencies.
It seems science-fiction, but that time will come.
Only what you have to do is putting your thumb in your ear and your pinky on your mounth and we can call, but the only problem i found is how can we dial a number. Could it be thinking or will there be a tiny chip in our brain that operates as central system for dialing numbers.
its awsome really. i think this may b the worlds slimest diaplay..
Using the body to transmit signals...
This may be the best way to send signals to the nanobots I'm working on.
