Abstract
- A single stack of double poled piezoelectric ceramic elements (202) create a monolaminar bender bar (200) which can be used in acoustic applications. The stack is lined up such that adjacent elements (202) in bender bar (200) have oppositely poled top and bottom sections. A positive voltage (230) is connected to electrical connection plates (214) which are positioned between every other piezoelectric element (202) in the stack and a negative voltage (232) is connected to electrical connection plates (214) which are between the remaining piezoelectric elements (202). Applying a voltage causes the stack to bend, wherein the piezoelectric elements (202) in the top half of the bender bar (200) all expand while the piezoelectric elements (202) in the bottom half of the bender bar (200) all contract.
