摘要:
The invention relates to a method for producing a piezostack, whereby the asymmetry of the electrically inactive zones (2, 2.1, 2.2) in a piezostack (5) having electrically inactive zones (2, 2.1. 2.2) on a plurality of sides thereof is determined, and the electrically inactive zone with an oversize is then reduced until the asymmetry reaches an acceptable proportion.
