METHOD FOR PRODUCING A CORRELATION BETWEEN A FIRST STATE AND A SECOND STATE OF A PIEZOELECTRIC COMPONENT, AND THE USE OF SAID CORRELATION

摘要

a) a first group oc components respectively in the first state is prepared (101), b) at least one defined characteristic of each component of the first group is determined (102), c) the piezoceramic element of the components of the first group is polarised, and a corresponding component of a a cecond group in the second state is thus created from each component of the second group is determined (104), and e) the correlation is produced by comparing the defined characteristic of each component of the first group with the defined characteristic of the corresponding component of the second group (105). Said component is, for example, an actuator body (20) having a monolithic multilayer structure. The correlation produced is used for the quality assurance of the actuator body.
