Abstract
Systems, devices, and methods employ advantages of ultrasonic vibration in the field of electrospinning. Fibers are produced from an ultrasonic nozzle exposed to an electric field established between the nozzle and a target object. Exemplary embodiments include electrospinning techniques that produce fine and ultrafine fibers in a high throughput via multiple jetting of spun solutions and melts. Ultrasonic vibration, in some instances combined with heating, reduces the voltage required for spinning. Vibrating power delivered to the nozzle may be selected so gas bubbles are generated by solvent cavitation in the spun solution. The bubbles are generated at the nozzle exit or else in such positions of the solution path so as to reach the nozzle exit where they further enhance multiple jetting of spun solutions.
