Description
形状変化材料は形状記憶材料層の表面上に導電性の層を有する形状記憶材料を含んでいる。導電層は例えば10ミクロン程度の厚さのフレキシブルな層であることができる。導電層は金属層または導電性のポリマー層であってもよく、化学蒸着または物理的気相蒸着のような蒸着によって、または電気めっきのようなめっきによって形成されることができる。導電材料は電気抵抗加熱により形状メモリ材料を加熱するために使用されることができる。導電材料は形状記憶材料において軟化または形状変化を生じるための加熱を与える一次ヒーターであってもよく、または一次ヒーターからの多量の熱を伴う二次ヒーター、例えば導電材料から形状記憶材料の対向面上の形状記憶材料の表面へ電気抵抗加熱を行う導電プレートであってもよい。形状変化材料は導電層表面と対向する導電層の表面上に絶縁層のような付加的な層を有することができる。絶縁層は、導電層からの熱損失を阻止し、導電層からのより多くの熱を形状記憶材料に誘導するように導電材料層を熱的に絶縁するために使用されることができる。形状変化材料の1つの使用法は形状変化材料のスキン材料として使用することである。このような使用法では、導電材料層は形状記憶材料と翼の外部表面との間に位置されることができる。
