Smart structures, structures containing sensor(s) and actuator(s) along with computational and control capabilities, are considered one of the best candidates for vibration control applications. A [0/90]6s glass-fiber composite plate embedded with one optical fiber and six piezoelectric elements has been fabricated, analyzed, and experimentally validated. It is shown that by using the in-situ optical fiber as a Michelson interferometer to detect the structural displacement and the piezoelectric elements as actuator, bending vibrations of the composite laminated plate can be effectively reduced.
