| 摘要 |
A flextensional transducer, including a generally disc-shaped piezoelectric member having a generally flat top surface and a generally flat parallel bottom surface, a top electrode formed on the top surface, a bottom electrode formed on the bottom surface, a top endcap operationally connected to the top surface, and a bottom endcap operationally connected to the bottom surface. The top and bottom endcaps are formed of shape memory material. The endcap exerts a radial stress upon the generally disc-shaped piezoelectric member.
