The concept of smart structures is based on intelligent materials giving the means to react on external stimulation by changing local mechanical properties. The market needs a high degree of integration of all components: sensors, actuators and electronics. At present, three different low profile piezocomposite actuator types are commercially available. The designs are arising from the Research and Development work at MIT (Massachusetts Institute of Technology) in the years 1991/92 funded by the US Department of Defence. Recently the German Aerospace Center, DLR, Braunschweig has developed a flexible and reliable PZT (Lead Zirconium Titanate) wafer based design. Smart Material GmbH is manufacturing the Macro Fiber Composites, licensed by NASA (National Aeronautics and Space Administration) in a full-scale production. An update on availability and developments of low profile piezoelectric sensors and actuators is presented.
