The present invention is a material and method that enables creation of an in situ pumping action within a matrix or otherwise porous media. This pumping action may be used to move materials, namely fluids, through the matrix or porous media to a gathering point. This pumping action may also be used as a vibrational source, using the movement of the matrix itself as the radiator of vibrational, typically acoustic, energy. This vibrational energy may be used for a variety of purposes.
