The Macro Fiber Composite (MFC) is the leading low-profile actuator and sensor offering high performance, flexibility and reliability in a cost- competitive device. The MFC was invented by NASA in 1999. In 2002, Smart Material started commercializing this patented invention worldwide as its licensed manufacturer and distributor. Since then, the MFC has been continuously improved and customized to fit customers’ specific needs and to meet the requirements for new applications.

The MFC consists of rectangular piezo ceramic rods sandwiched between layers of adhesive, electrodes, and polyimide film. The electrodes are attached to the film in an interdigitated pattern which transfers the applied voltage directly to and from the ribbon-shaped rods. This assembly enables in-plane poling, actuation, and sensing in a sealed and durable, ready-to-use package. The MFC can also be applied (normally bonded) as a thin, surface-conformable sheet to various types of structures, or embedded in a composite structure. If voltage is applied, it will bend or distort materials, counteract vibrations, or generate vibrations. If no voltage is applied it can work as a very sensitive strain gauge, sensing deformations, noise, and vibrations. The MFC is also an excellent device to harvest energy from vibrations.

MFC P1 type (d33 effect), Elongator

The P1 type MFCs, including the F1 and S1 types, utilize the d33 effect for actuation and will elongate up to 1800ppm if operated at the maximum voltage rate of -500V to +1500V. The P1 type MFCs are also very sensitive strain sensors.
