Abstract

The "Standardized Electodisplacive Transducer" or the SELECT actuator combines a novel fabrication methodology with state-of-the-art lead magnesium niobate (PMN) electrostrictive materials to produce a new generation precision displacement transducer. Historically, PMN actuators have undergone a plethora of material and process modifications to make a more reliable and reproducible device. Actuator designs were also custom for each individual application. The SELECT actuator concept provides a standardized actuator configuration with fixed geometries, fixed active layers number, and fixed process parameters consistent with large scale production. Technical improvements include increased sensitivity, improved uniformity, and larger displacements. In addition SELECT provides significant fiscal advantages. When fully integrated into the production facility, actuator costs are potentially reduced to less than $100 per channel with no long lead materials and a significantly reduced schedule.
