Device for the body-bound data transmission between two terminals

Device for transmission of data between two terminals, comprising:

• a first terminal adapted to be worn on a body of a living being, and having an interface including a pair of electrodes for coupling electric data signals, at least one of into and out of the body, for transmission via the body;
• and
• a second terminal situated on a device for at least one of sending and receiving signals, which device has a touch-sensitive interface including a pair of electrodes which are operative when touched by the body bearing the first terminal, to couple data signals at least one of to and from the first terminal via the body of the living being;
• wherein
• the interface of the first terminal has a first pair of electrodes positioned to make contact with a first pair of mutually spaced points of the body;
• the interface of the second terminal has a second pair of touch-sensitive electrodes adapted to be touched by a second pair of mutually spaced points of the body;
• and
• the electrodes of the first terminal are positioned to make contact with mutually spaced apart points on the body of the living being, and the electrodes of the second terminal are mounted separate from the body and adapted to be contacted by two different appendages of the body;
• whereby a data signal to be transmitted by the first terminal is coupled as a differential voltage signal by way of the first pair of electrodes into the body of the living being and is coupled out of the body by the second terminal as a corresponding differential voltage signal by way of the second pair of electrodes.
