This work reports on the fabrication and studies of highly piezoelectric composite fibers. The polylactic acid fibers embedded with barium titanate were created using the standard electrospinning method and utilized the high electric fields required for the electrospinning process. Fibers with micron and sub-micron diameters were spun together to produce fibrous mats. These fibrous mats were analyzed for both their direct and converse piezoelectric properties. The converse piezoelectric effect was measured by applying both DC and AC fields to see the electromechanical response of the mats by looking at the movements of the mats. Along with this, the direct piezoelectric effect was measured by applying mechanical forces to the mats, and measured its electrical response. It was found that the piezoelectric coupling constant of the fibrous mat is larger, per weight, than that of single crystal barium titanate films. These materials, unlike the crystalline films, are flexible and can be beneficial in such things as bio-sensors, artificial muscles, and energy harvesting devices. Along with being flexible, the electrospinning process can be used to make similar composite fibers with materials tailored to a desired need, allowing for a multitude of applications to be considered for this method of creating piezoelectric composite fibers.
