Electrospinning is a process used to create ultra-fine fibers from polymer solutions or melts by applying a high voltage to produce a charged jet that stretches and solidifies as it travels towards a collector. This technique is important because it allows for the production of nanofibers that can have piezoelectric properties, making them suitable for energy harvesting applications. The resulting fibrous structures can be integrated into various materials, enhancing their functionality, especially in the development of new textiles and accessories.
