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.

当前可用通信技术的物理形式分为一个或三维通信。一维通信是电缆的通信，其中电磁能限制在一维介质中。三维通信是通过无线电通信。在这个项目中，我们提出了一种新的物理形式，其中电磁能限制在二维介质中。这些元素通过邻近连接通过介质发送/接收信号，没有任何电线。该技术使我们能够将大量传感器植入墙壁，书桌，地板和衣服的各种材料上。元素以高通量通信，并带有电力。能源消耗小于通常的无线电通信。一种开发的方法基于微波传输。我们阐明了通信表的简单结构可以局限电磁波。然后，我们在板和传感器节点之间开发了一个有效的接近连接器。我们表明，高速通信和能源供应均已实现。项目中开发的另一种方法是细胞桥系统。在系统中，通信芯片位于多个导电部位的边界。它还使我们能够实现没有长电线的高密度传感器阵列。使用该技术，我们制造了具有丰富感应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沟通形式，并在各种应用中展示了实用性的NESS。
