<p><P>PROBLEM TO BE SOLVED: To provide a system for commonly poling piezoelectric elements. <P>SOLUTION: This system for poling piezoelectric elements includes a plurality of thin-film components, a plurality of piezoelectric elements, a poling pad for poling the piezoelectric elements, a plurality of traces, and a plurality of current-limiting elements. The thin-film components are separated by dice lanes to form an array, and the piezoelectric elements are formed on the thin-film components. The traces connect the piezoelectric elements across the dice lanes in parallel to the poling pad. Each current-limiting element is connected in series with one of the piezoelectric elements, in order to limit current to individual piezoelectric elements that cause current-related failure. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
