Abstract
A piezoelectric fabric can include: a non-woven, continuous fiber mat comprising: a polymer; and a plurality of piezoelectric ceramic particles. The piezoelectric fabric can be produced by electrospinning. The method of electrospinning can include: forming a continuous fiber of material comprising: flowing a fluid through a needle, wherein the fluid comprises: the polymer; a base fluid; and the piezoelectric ceramic particles; and applying a voltage to create an electric field between a tip of the needle and a collector during fluid flow; and collecting the continuous fiber on the collector. The piezoelectric fabric can exhibit improved performance and piezo thermal stability.
