Using Your Hand as a Remote Control

The Denso Corporation has created an electric ring named Yubi-nya that can be used as a remote control. Wearers of the ring can operate devices and control remote processes by just pressing two fingers together. The ring produces a weak electric current that is conducted outwards through the user’s index finger. When the tips of the finger and the thumb are brought together, the current travels back around through the hand to the ring and activates  a radio signal that’s sent out to a remote device.

Denso has demonstrated the device as a control for opening and closing the door of a model car, but see many more uses for their device in the future, such as a control for a music player. They are also working on making it smaller and less obtrusive.
