Abstract: Apparatus for the prevention of the formation and the removal of previously formed ice from the surface of various articles. A piezoelectric material is applied to environmentally exposed surfaces which are meant to be kept ice free. An available power source is adapted so that whatever the source, it is converted into an alternating current. A microprocessor is provided that, in accordance with the type of material used, its thickness, its currie point, and any other parameters of the specific piezoelectric material necessary for consideration, that it receives a current of the proper amplitude, duration, wave length, and shape which will realize the amount of movement or deformation of the piezoelectric material necessary to prevent ice formation. Further, the piezoelectric material is applied in a grid formation which enables the microprocessor to magnify the deformation of the material and to receive feedback information from specific areas as to the temperature, pressure, density, size of raindrops, etc.
