Systems for fiber guidance

Abstract

WSU inventor: Richard Sack, Innovation Hub, College of EngineeringApplication No: 18/775,113 filed July 17, 2024. Patent No: US 2025027230 A1 granted January 23, 2025.Provided herein is a system for guiding polymeric fibers using ultrasonic waves. In particular, this application dis­closes a system of producing fibers including an emitter, a fiber guidance system, and a collector. The emitter supplies the polymer jet into the fiber guidance system. The fiber guidance system includes a phased array of transducers and a control system. The control system directs the phased array of transducers to generate acoustic energy to create an acoustic hologram and guide the polymer jet in space to form the polymer fiber before it is collected in the collector
