Commonly-poled piezoelectric device

摘要

A system for poling piezoelectric devices comprises a plurality of thin-film components, a plurality of piezoelectric devices, a poling pad for poling the piezoelectric devices, 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 devices are formed on the thin-film components. The traces connect the piezoelectric devices across the dice lanes in parallel to the poling pad. Each current-limiting element is connected in series with one of the piezoelectric devices, in order to limit current to individual piezoelectric devices that experience current-related failure.
