Electro-electret

Japanese: エレクトロエレクトレット - えれくとろえれくとれっと
Electro-electret

…Electrets are classified according to the method used to create electric polarization in an insulator. Thermal electrets are made by heating and melting a material and orienting the molecules with an electric field, while electric electrets are made by polarizing a thin dielectric film with a strong electric field. Other methods for orienting molecules include using the photoelectric properties of the material to irradiate light and apply a voltage, using gamma rays or electron beams to separate charges, and using a magnetic field to polarize the material. …

*Some of the terminology that refers to "electroelectret" is listed below.

Japanese:

…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。熱エレクトレットは,物質を加熱溶融して電場によって分子を配向させてつくり,電気エレクトレット(エレクトロエレクトレット)は,薄膜の誘電体に強い電場をかけて分極させてつくる。そのほか分子を配向させる手段として,物質の光電特性を利用して光照射と加電を行う方法,γ線や電子線によって電荷分離を行う方法,磁場によって分極させる方法がある。…
