Since they have the ability to act as both a sensor and an actuator, piezoelectric materials have been described as a ‘natural’ smart material. With the development of piezoceramic fibers and fabrics, functional composites consisting of these fib

A dome piezoelectric-electrostrictive monolithic bilayer composite (PE-MBLC) actuator is attached to a thin metallic plate by insulating epoxy resin to form a flextensional actuator. Such flextensional actuator is called bilayer piezoelectric/electro

Bi-based piezoelectric ceramics are a good candidate to replace lead zirconate titanate (PZT) for use as multilayer actuators (MLA) in diesel fuel injectors due to their moderate piezoelectric properties at room temperature. Current MLA use PZT with
