The goal of this project was to develop a family of inexpensive hydrophone andor projector designs utilizing Macro Fiber Composite MFC patches. The MFC is a low profile 0.0 12 actuator and sensor invented by NASA in 1996 and manufactured by Smart Material Corporation. The MFC utilizes a layer of rectangular piezo ceramic rods that are encapsulated between layers of adhesive, polyimide film and interdigitated electrodes. The MFC is assembled in a sealed package, which makes them durable, highly flexible, inexpensive and easily applied. The patch has high actuation authority and can be stacked to provide improved force characteristics. The MFC has been used to bend and twist structures for NASA and Air Force applications.
