Dancing Electrohydrodynamic Tip Streaming Modulated by Faraday Instability.

ABSTRACT: Tip streaming enables flow transitions from the millimeter scale to the microscale and even nanoscale, generating tiny droplets with broad applications in precision 3D printing, nanomaterial fabrication, and drug delivery. In these applications, high-frequency jetting is required to improve efficiency. However, understanding and controlling high-frequency tip streaming remain challenging. Here, a series of dancing electrohydrodynamic (EHD) tip streaming phenomena is reported, characterized by subharmonic ejection modes under high-frequency electric fields. The underlying mechanism of this intriguing phenomenon is elucidated, which stems from global meniscus oscillations induced by Faraday instability, followed by jetting at the Faraday wave crests due to local interfacial instability.
