  "textContent": "The invention describes a method and an apparatus for uniformly polarizing a piezoelectric element that, for example, can be used as an actuator in a fuel injection system of an internal combustion engine. The method and apparatus are characterized in that a polarization voltage signal is applied to the piezoelectric resulting in uniform polarization of the piezoelectric element while ensuring that an incorrect fuel injection action does not occur.",
