Title: Tomotsugu Kanamura: Innovator in Electromagnetic Interference Shielding
Introduction
Tomotsugu Kanamura is a notable inventor based in Nagoya, Japan. He has made significant contributions to the field of materials science, particularly in the development of conductive materials with electromagnetic interference (EMI) shielding capabilities. With a total of 3 patents to his name, Kanamura's work is recognized for its innovative approach to enhancing the functionality of textiles and other materials.
Latest Patents
One of Kanamura's latest patents is a conductive sheet that possesses an electromagnetic interference shielding function. This conductive sheet is composed of a nonwoven fabric that includes 40 to 90 wt % of a heat fusible fiber made from a vinyl chloride/vinyl acetate copolymer, along with 10 to 60 wt % of a metal-plated fiber. The fibers have a diameter ranging from 3 to 50 micrometers and an aspect ratio of 1,000 to 10,000. The nonwoven fabric is hot-press molded, resulting in a conductive sheet with a metal content of 2 to 30% by weight and a specific volume of at most 2 cm³/g. This innovative sheet exhibits excellent EMI shielding and electrical control effects.
Another significant invention by Kanamura is the thin-metal-wire conjugated yarn. This yarn is designed for clothing applications and features EMI shielding properties. It consists of a core made from a thin metal wire with a diameter of 50 micrometers or less, surrounded by a chemical or synthetic fiber or natural fiber yarn. Additionally, another yarn serves as a sheath, wound around and coated on the core, with a coating percentage of 70% or more based on the surface area of the conjugated yarn.
