In a method for polarizing a piezoceramic material, first, a base is provided that is made of non-polarized piezoceramic material and has at least two opposite planar electrodes and at least one predetermined breaking point because of which a stress relief fracture forms when a voltage having a first voltage value is applied. A number of voltage pulses, the amplitudes of which follow a time-related envelope curve, is applied to the electrodes of the base. The amplitudes of the voltage pulses in a first section of the envelope curve are higher than the first voltage value, and the amplitudes of the voltage pulses in a second section of the envelope curve that follows the first section have a second voltage value which is sufficient to permanently polarize the piezoceramic material.
