In this paper, we report the latest results of our two-dimensional communication project. In the system we show here, the sensor node that touches the surface of a two-dimensional signal transmission sheet (2DST sheet) establishes the connection. The system allows free location of the sensor node, and proximity (non-contact) connection is realized stably. The structure of 2DST sheet is simple and realized with various materials at low cost. Since the sensor nodes communicate with electromagnetic waves confined in two-dimensional medium, they are free from the interference from the nodes apart from the sheet. Powering with microwave through the sheet is also possible.
