마이크로채널에서 서브킬로헤르츠 진동 흐름의 생성을 위한 외부 드라이버의 조립 및 특성화

Executive Industry Relevance

Oscillatory flow enhances mixing and reaction kinetics in microfluidic assays, yet its adoption is limited by cost and complexity of existing systems. This low-cost, plug-and-play speaker-based apparatus enables high-fidelity oscillatory flow generation from 10-1000 Hz with independent amplitude control, addressing a key technical barrier in microfluidic workflows. By providing a reusable, detachable solution compatible with steady flow systems, it supports predictive de-risking in assay development and phenotypic screening through improved fluidic control and reproducibility.
