• Piezoelectric progress: a fantastic voyage-
  Understanding piezoelectricity may soon become essential to Electromechanical knowledge. EA's special correspondent Barbara Wolcott discusses research in the field of adaptive structures and piezoelectricity over the course of the last 20 years. She offers a look at the way in which flag adaptive rotor helicopters were developed with support from the National Science Foundation. Once the design matured, it was turned over to DARPA. The project has progressed well and is now being developed for support of armed forces in the U. S. and around the world. Such development has given rise to another family of adaptive structures that enable aircraft to become invisible to the naked eye.
