RedTacton

"Intra-body communication" using the human body as a transmission medium have been reported, but the electric field/photonics method employed by RedTacton is superior to conventional methods in terms of communication distance, speed, and interactivity.

P: Possible
N: Not possible
P*: Possible under certain conditions

Signal & Detection system	Ground line	Distance & speed	Duplex communication		Contact status with the electrode
Signal & Detection system	Ground line	Distance & speed	Between mobile terminals	Between mobile terminals and external equipment	Contact status with the electrode
Amperage electric	Clear signal lines needed for body and earth ground	Elbow to fingertip at approx. 3kbps	N	P*	The electrode must be in constant contact with the body to maintain good conductivity
Voltage electric	Capacity coupling between the earth ground and equipment	Wrist to fingertip at approx. 1kbps	P*	P*	Communication possible even when passing through thin insulators
Electric field electric (RedTacton)	Capacity coupling between the earth ground and equipment	Anywhere on the body at 230kbps	P	P	Communication possible even through shoes and clothing
Electric field photonics (RedTacton)	Capacity coupling between the earth ground and equipment	Anywhere on the body at up to 10Mbps	P	P	Communication possible even through shoes and clothing

RedTacton does not require the electrode be in direct contact with the skin. High-speed communication is possible between two arbitrary points on the body.

With the electric amperage method, a clear signal line and ground line are required. With the electric voltage method, capacity coupling can substitute. Therefore, the electrode does not have to be in direct contact with the skin.
