Abstract:Piezoelectric materials are capable of actuation and sensing and have been used in a wide variety of smart devices and structures. Active fiber composite and macro fiber composite are newly developed types of piezoelectric composites, and show superior properties to monolithic piezoelectric wafer due to their distinctive structures. Numerous work has focused on the performance prediction of the composites by evaluation of structural parameters and properties of the constituent materials with analytical and numerical methods. Various applications have been explored for the piezoelectric fiber composites, including vibration and noise control, health monitoring, morphing of structures and energy harvesting, in which the composites play key role and demonstrate the necessity for further development.
