Abstract

In this paper, we report the development of a biologically inspired fluidic diode motivated by xylem pores in plants. The biologically inspired fluidic diodes allow to design large-scale microfluidic circuits and simple fluidic controls. It requires only a single-layered device and a single pressure source to regulate flow through the entire platform. The operational conditions are precisely estimated based on a fully developed analytical model, which considers the hysteresis of contact angles and effects of fabrication limitations. Using biologically inspired fluidic diodes, we have demonstrated a large-scale spontaneous droplet-patterning and microfluidic co-culture array.
