<p>A method for operating a piezoelectric element is disclosed. A first voltage is applied to a piezoelectric element and produces a first deflection of the piezoelectric element with a travel. An electrical discharge of the piezoelectric element after the application of the first voltage results in a first contraction of the piezoelectric element by a first compression. After the first contraction, a second voltage is applied to the piezoelectric element, whose polarity is opposite that of the first voltage and causes a further contraction of the piezoelectric element by a second compression. Repeated application of the first voltage after the electrical discharge of the applied second voltage results in a deflection of the piezoelectric element with the same travel.</p> |
