Piezoelectric transducers are commonly utilized for ink jet ejectors. It has been found, however, that the fabrication process for these assemblies is limited by the need to keep the process temperature below that which would cause depoling of the transducer. This problem can be circumvented by using electrostrictive trans-ducers that are not poled, hence have no depoling temperature, in place of the conventional piezoelectric transducer. Further, materials with a high electro-strictive constant are easier to fabricate, and the devices are generally less expensive.
