Paper Abstract

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