    Abstract

    Piezo Electric Materials capable of performing both “sensing” and “actuation” are known as smart materials. These materials produce electric charges on application of mechanical stress (as sensor) or undergo dimensional change when subjected to an electric field (as actuator). PZTs are preferred because of their (i) fast response time, (ii) high frequency response, (iii) precession control etc. Piezo sensors and actuators are used for various applications e.g. for vibration control of aerospace structures, development of smart aeroplane wings / morphing structures, precision flow control of propellants in space vehicles, fuel flow control in automobile engines, energy harvesting etc. At NAL, efforts are being made to prepare PZT materials, multi-layered actuators are currently fabricated and characterized for aerospace applications.
