The mechanical properties of electrospun fibers play an important role in determining their applications. Most of the reported literature measures the mechanical properties of electrospun mats, scaffolds, or films instead of single fibers; however, a basic understanding of the relationship between the mechanical properties of the single fiber and that of the mat is critical to obtain precise information for choosing their application. This Review aims to evaluate the reported mechanical properties of electrospun fibers and the variables that influence those properties. An overview on the recent inputs in the development of mechanical properties of electrospun fibers is given, illustrating attempts to tailor mechanical properties of the fibers and/or mats. The necessity of determining flexible and reliable testing methods to establish testing standards for obtaining consistent and reliable data for both electrospun fibers and mats is also highlighted. Herein, the mechanical properties of electrospun fibers and mats are reviewed to understand the basic relationship between the mechanical properties of the single fiber and those of the mat. The necessity of reliable testing methods to establish testing standards for obtaining consistent and unbiased data for both electrospun fibers and mats is emphasized.
