High-speed three-dimensional characterization of fluid flows induced by micro-objects in deep microchannels

& Kerem Pekkan
Bio-inspired studies of micro-objects in microfluidics demand quantitative microflow visualization tools to evaluate their three-dimensional (3D) fluid dynamic performance. Experimental fluid dynamic measurements of bio-hybrid systems are employed when non-traditional small-scales, magnetohydrodynamic coupling and nonlinear material properties are involved. In this study a stereoscopic micro- Particle Image Velocimetry(μPIV) system was developed to characterize instantaneous flow fields induced by (1) a micro-robot (280×200×150 μm3) and (2) self-assembled magnetically actuated artificial cilia (∼50 μm in diameter and...
