Abstract: 電気的に分離可能な形態の面ファスナ（１０）は、いずれかに直接物理的な力を加えなくても、ファスナの片側部分を他方から外すことが可能である。ファスナのフック素子（２１）は、ニニトールのような形状記憶合金材料（２７）で構成される。ループの片側部分（１２）からファスナのフックの片側部分（１４）を外すには、フック（２１）を直線化させるため形状記憶合金材料に通電し、ループ（１８）でのこれらの掛け合わせを外すようにする。フックの片側への通電によって、ニニトール材料（２７）が活性化され、その形状が変化し、全長部が伸長または収縮する。形状の変化は別の材料の全長部（２８）にも影響を及ぼし、全長が固定されたままで、または反対方向に形状が変化して、フック形状からロッド形状への直線化が生じることとなる。電気エネルギーの流れが消滅すると、フック（２１）はフック形状に戻り、２つのファスナ片側部分が通常のように合わされれば、再びループ（１８）での掛け合わせが可能となる。外すことと再度掛け合わせることは実質上、何回も繰り返し行うことが可能である。
