Transfer a secret audio message by poking someone with your finger

The video seems to be a completely different and much cooler thing that messages by poking.

It would be pretty cool if they'd license the tech to cellphone OEMs so touchscreens would be easier to use.

This is actually an old idea, perhaps a hundred years old. It was patented in 1972 (3,647,970 Flanagan) and called the "neurophone", but I recall an article about something like it from the 1920s.

I'm not sure I want other people stick their finger in my ear, even if they aren't doing it to electrocute me.

I noticed that my MacBook does this as well. If I touch the case then touch my ear while it's charging I hear a buzzing sound and feel my fingers tingling where they touch the laptop. I always wondered how the buzzing was transmitted.

Now people won't have to text to talk to someone a few feet away.
