Abstract
Smart materials based on 1-3 piezocomposite transducers, capable of both sensing and actuation, are being developed for active control applications. Large area, low profile SmartPanels, consisting of 1-3 piezocomposite actuators and pressure sensors and net-shape-molded PZT accelerometers, have been fabricated and evaluated for surface mounted boundary control applications. Single layer and two-layer 100 X 100 mm and 250 X 250 mm SmartPanels have been tested for actuator authority, surface displacement uniformity, sensor-actuator coupling, and surface vibration reduction. Single layer SmartPanels have shown broad band 20 dB surface vibration reduction.
