Abstract: 絶縁材料からなる対象物の場合、その表面に導電ワイヤ（３）と、導電性の薄膜(５)を互いに対向するよう取り付け、導電ワイヤと薄膜との間にパルス電圧を印加する。また、導電性材料からなる対象物の場合、その表面に絶縁被覆を施した導電ワイヤからなる絶縁被覆導線(３)を取り付け、対象物と導電ワイヤとの間にパルス電圧を印加する。これにより、導電ワイヤの周囲に沿って表面プラズマを発生させ、誘起気流を発生させる。ワイヤ式プラズマアクチュエータであるため、風力発電・航空機・ガスタービン等の３次元形状の翼型や、トラック等の自動車外壁等の対象物に対しても、取り付け面積、周辺の流体流れに与える影響を最小限にとどめた上で、最適位置に簡単に装着することができる。
