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 method for producing a correlation between a first state of a piezoelectric component (1, 20) comprising a piezoceramic element and a second state of the component comprises the following steps: a) a first group of 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 second group in the second state is thus created from each component of the first group (103), d) at least one defined characteristic of each component of the second group is determined (104), and e) the correlation is produced by comparing the defined characteristics of each component of the first group with the defined characteristic of the corresponding component of the second group (105).
