Abstract
A piezoelectric fiber composite and a magnetoelectric laminate composite including the same are disclosed. The piezoelectric fiber composite includes a first protective layer having a first electrode, a second protective layer having a second electrode, and a piezoelectric fiber layer formed between the first and the second electrode and having piezoelectric fibers arranged in the longitudinal direction of the composite, wherein the piezoelectric fibers include a single-crystal piezoelectric material and are configured such that a <011> direction of the single crystal is identical to a thickness direction of the composite and a <001> direction of the single crystal is identical to a longitudinal direction of the composite, thus exhibiting superior piezoelectric strain properties and sensing properties. Also, the magnetoelectric laminate composite includes the piezoelectric fiber composite and a magnetostrictive layer including a magnetostrictive material such as nickel (Ni) or Metglas (FeBSi alloy), thus ensuring significantly improved magnetoelectric properties.
