Abstract

Sensor/Actuator coupling is a key parameter in the design of smart actuators (or systems) for sound and vibration control applications. To be practical, however, such a combination of transducers (actuator and sensors) must be available as an inexpensive ready-to-use electromechanical component with predictable well-behaved controllable characteristics. One approach NRL is currently pursuing toward reducing fabrication costs is to use the injection molding process developed by Materials Systems Inc. to co-form the accelerometer and actuator in one fabrication step. This results in an actuator with an imbedded array of accelerometers, where the inclusion of the accelerometer array adds little to the cost of the actuator. This low-cost fabrication approach is also applicable for aerospace vibration control or robotic sensing applications. This paper describes the design, and performance of prototype accelerometers and accelerometer/actuator systems formed using this process.
