...The name was coined in response to the fact that magnets are created when a ferromagnetic material is placed in a magnetic field and becomes magnetized. The first electret was created in 1924 by Gentaro Eguchi, who was the first in the world to create a material by melting a mixture of carnauba wax and rosin, applying a direct current voltage to electrically polarize it, and solidifying it. Electrets are classified according to the method used to create electrical polarization in insulators. ... *Some of the terminology that mentions "Gentaro Eguchi" is listed below.

…磁場の中に置いた強磁性体が磁化してできる磁石をマグネットmagnetと呼ぶのに対応して名づけられた。エレクトレットは,1924年江口元太郎が世界に先がけてカルナバ蠟と松やにを混合して溶融し,直流電圧を加えて電気分極して固めてつくった物質が最初である。エレクトレットは,絶縁体の中に電気分極を起こさせる方法によって分類する。… ※「江口元太郎」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
