Akimasa Okada, Yasutoshi Makino, Hiroyuki Shinoda · 2005
Abstract: In this paper, we propose a novel communication system in networked sensing field. The network is constructed by combining multiple two-dimensional areas called “cells ” where signals propagate with communication elements called “cell bridges ” and requires neither radio technologies nor long wirings. The property of the proposed system enables us to construct high-density sensor sheet on various materials. We show the physical layer and the data link layer of the cell bridge. We developed a prototype cell bridge based on CMOS technology. The experimental results showed the proposed system is capable of high-speed communication on stretchable clothes.
