The Macro-Fiber Composite (MFC) actuator is a low-cost piezoelectric device designed for controlling vibration, noise, and deflections in composite structural beams and panels. It is an encapsulated, high-performance, in-plane, piezoelectric fiber composite strain device that consists of rectangular piezoelectric fibers sandwiched between layers of adhesive and electrode polyimide film.

The MFC design incorporates easy-to-handle macrofibers in a simple and repeatable manufacturing process and places these fibers close to the electrodes to reduce voltage requirements. Thus, the advantages of the fiber's high strain energy, directional actuation, conformability, and durability are retained. When embedded in a surface or attached to flexible structures, the MFC actuator provides distributed, solid-state deflection and vibration control.
