Abstract
Techniques to enable near field communication using electric field (E-field) are proposed. When the wavelength of a signal is long relative to the human body, the human body can behave as a conductive hollow cylinder. By capacitively coupling the human body with a transmitter and/or a receiver, the human body itself can be used as a communication medium.
