A method and structure is disclosed for forming a removable interconnect for semiconductor packages, where the connector is adapted to repeatedly change from a first shape into a second shape upon being subjected to a temperature change and to repeatedly return to the first shape when not being subjected to the temperature change. The plezoelectrlc actuator has a piezoelectric film, a first electrode, a second electrode, and a third electrode. A piston is disposed in the piston chamber for reciprocal movement between the first and second ends of the piston chamber to alternatingly define first and second volumes therein. The system also includes an output stage coupled to the secondary winding and that generates an output voltage based on the current induced in the secondary winding. A posterior support is coupled to the carrier harness panel and is configured to support a posterior portion of a pet.
