A bimorph is a cantilever that consists of two active layers: piezoelectric and metal.〔http://www.physikinstrumente.com/en/products/primages.php?sortnr=400800.10〕 These layers produce a displacement via: * thermal activation (a temperature change causes one layer to expand more than the other). * electrical activation as in a piezoelectric bimorph (electric field causes one layer to extend and the other layer to contract). A piezoelectric unimorph has one active (i.e. piezoelectric) layer and one inactive (i.e. non-piezoelectric) layer. ==See also== *Unimorph *Inchworm motor 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「bimorph」の詳細全文を読む スポンサード リンク
