1-3 piezocomposite SmartPanels

摘要: Piezocomposite SmartPanelsTM, consisting of 1-3 actuators and pressure sensors net-shape-molded PZT accelerometers in a large area low profile panel, have been fabricated at Materials Systems Inc. evaluated the Naval Research Laboratory. Single layer two-layer 100 X mm SmartPanels tested for sensor sensitivities, actuator authority, surface displacement uniformity, sensor-actuator coupling. Multilayer GRP circuits boards are used both as stiff faceplates to provide electrical connections ground planes. The SmartPanel technology has recently scaled up 250 devices. draw upon (lead zirconate titanate) ceramic injection molding technology, which is produce cost-effective robust piezoelectric ceramic-polymer composite materials. materials extensively SonoPanelTM transducers number applications. SonoPanels qualified US Navy applications, based on successful completion shock tests, currently being from 750 panels. Several applications described, including conformable transducers, multielement arrays, sensors, velocity sensors.
