项目摘要

The physical forms of currently available communication technologies are categorized into one or three dimensional communication. One-dimensional communication is communication by cables in which electromagnetic energy is confined in one dimensional medium. Three-dimensional communication is communication by radio. In this project we proposed a new physical form of communication in which electromagnetic energy is confined in a two-dimensional medium. The elements send/receive signal through the medium by proximity connection with no individual wires. The technology enables us to implant a large number of sensors on various materials of walls, desks, floors, and clothes. The elements communicate at high throughput, being provided with electrical power. Energy consumption is smaller than that of usual radio communication.One developed method is based on microwave transmission. We clarified a simple structure of communication sheet can confine the electromagnetic wave. Then we developed an efficient proximity connector between the sheet and the sensor node. We showed that both high speed communication and energy supply are realized. Another method developed in the project is Cell-bridge system. In the system, the communication chips are located at the boundary of multiple conductive sites. It also enables us to realize a high-density sensor array with no long wires. Using the technology, we fabricated a stretchable robot skin with rich sensing abilities.In this project, we developed a new physical form of communication, and showed the practical useful ness in various applications.

目前可用的通信技术的物理形式分为一维或三维通信。一维通信是电磁能量被限制在一维介质中的电缆通信。三维通信是通过无线电进行的通信。在这个项目中，我们提出了一种新的物理通信形式，其中电磁能量被限制在二维介质中。元件通过介质通过接近连接发送/接收信号，没有单独的电线。这项技术使我们能够在墙壁、桌子、地板和衣服等各种材料上植入大量传感器。这些元件以高吞吐量进行通信，并提供电力。能耗比一般的无线电通信要小。一种已开发的方法是基于微波传输。我们阐明了一种简单的通信片结构可以限制电磁波。然后，我们在薄片和传感器节点之间开发了一个高效的接近连接器。同时实现了高速通信和能源供应。该项目开发的另一种方法是Cell-bridge系统。在该系统中，通信芯片位于多个导电点的边界上。它还使我们能够实现高密度的传感器阵列，而不需要长导线。利用该技术，我们制作了具有丰富传感能力的可拉伸机器人皮肤。在这个项目中，我们开发了一种新的物理通信形式，并在各种应用中展示了它的实用性。
