Domain polarization can affect the surface properties of ferroelectric oxides. Mechanical energy is exploited to enable direct chemical reactions on the ferroelectric surface by the piezoelectric effect. Transient local electrostatic potentials on ferroelectric surface evoked by external mechanical excitation through the piezoelectric effect can activate redox reactions in solution at predefined domain locations. Conversion of mechanical via electrical to chemical energy can thereby be realized.
