High performance piezoelectric actuator |
摘要 |
A high performance piezoelectric actuator. The actuator includes a piezoelectric material exhibiting a selectively tapered width sufficient to enhance actuator fracture load capabilities. A passive material is disposed on or integrated with the piezoelectric material. A drive system is connected to the piezoelectric material. The drive system is capable of selectively applying an electric field to the piezoelectric material. In specific embodiment, the piezoelectric material includes a curved piezoelectric layer exhibits a default state of compression along a surface of the piezoelectric layer. |
