The MFC is a device to harvest energy from vibrations.The MFC consists of rectangular piezo ceramic rods sandwiched between layers of adhesive, electrodes, and polyimide film.If voltage is applied across the electrode, it works as an actuator and will bend or distort materials, counteract vibrations, or generate vibrations. If no voltage is applied it can work as a very sensitive strain gauge.
