Piezoelectric fibers include a polypeptide wherein molecules of the polypeptide have electric dipole moments that are aligned such that the piezoelectric fiber provides a piezoelectric effect at an operating temperature. A piezoelectric component provides a plurality of piezoelectric fibers, each comprising an organic polymer. A method of producing piezoelectric fibers includes electrospinning a polymer solution to form a fiber and winding the fiber onto a rotatin target in which the rotating target is electrically grounded. An acoustic sensor includes a plurality acoustic transducers, wherein the plurality of acoustic transducers are structured and arranged to detect a corresponding plurality of vector components of an acoustic signal, and at least one of the plurality of acoustic transducers comprises a piezoelectric fiber.
