The Electronic Circuit Composition and Structure of String for a Novel Braid Electronics-Systems by Kumihimo Structure


The new integrated circuit concept that forms electronic equipment by the textile structure using the flexible fiber that has equipped the field effect transistor, the light emitting diode, the wiring pattern, etc. was proposed [1,2]. In this report, the structure of the filamentous body as a basic structure of the kumihimo with various electronic functions was examined. There are many kinds of one in the kumihimo by the number and how to unite the plaited thread used. Although such a highly efficient kumihimo-structure electronic integrated circuit can be realized using kumihimo with much thread, it becomes that much complicated. In order to simplify an argument here, square-type kumihimo that uses eight plaited threads is employed, and a basic logical circuit composition and the element arrangement on plaited thread are examined. Eight plaited-threads are divided into two groups that have four threads respectively, and they exist in the plane that intersected perpendicularly mutually. However, kumihimo is a 1-dimensional system fundamentally, it can be extended in the length direction if necessary, and it is considered that a quite complicated function is also realizable for a circuit with few input and output. Here, plaited thread that belongs to one group for convenience will be called warp and the other group will be called woof. The circuit composition and a concrete structure of threads for kumihimo are discussed.
