Abstract
A piezoelectric assembly is provided, including an electrode assembly, a signal electrical connector, and a reference electrical connector. The electrode assembly includes a first electrode, a second electrode, and a piezoelectric material. The signal electrical connector is in electrical communication with the first electrode and configured to be connected to the current or voltage source so as to provide electrical communication with a current or voltage source. The reference electrical connector is in electrical communication with the second electrode and configured to be connected to the reference source so as to provide electrical communication with a reference source. One of the signal electrical connector and the reference electrical connector includes a metal shim for supporting the electrode assembly. A flexible printed circuit board is provided including a trace. An interconnecting structure effects electrical communication between the trace and the metal shim. The interconnecting structure is disposed within a passage provided between a first side surface and an opposite second side surface of the flexible printed circuit board, and extends through the first side surface…
