Two-dimensional communication technology inspired by robot skin

A two-dimensional communication device proposed in a recent paper is a device in which signals travel freely between arbitrary points in flexible two-dimensional space using two-dimensionally-spread electromagnetic field. The new form of communication solves the wiring problems in various situations. It also has advantages over wireless communication. It consumes less energy for signal transmission, it can provide energy for the connected elements, and the communication capacity is larger because multiple 1D signal chains transmit signals simultaneously. In this paper, we demonstrate examples of high-speed signal transmission through flexible 2D layers with proximity interfaces.
