Microfluidic Stamping on Sheath Flow

Abstract

A microfluidic stamping method to form functional shapes on a cross section in fiber-shaped flow is proposed. Microfluidic stamping and overstamping allow various cross sectional shapes on the 3D flow. The shapes can be controlled by a change in combination of structures and fluidic conditions which correspond to stamp type and stamping force.

Keywords: 3D structures; complex cross sections; fiber-shaped materials; sheath flow.
