A high-efficiency passive micromixer using UV-adhesive mold

In this paper, a novel micromixer design, called Type-A micromixer and is very common component in the state-of-the-art lab-on-chip devices and occupies large chip areas to fulfill the rather challenging process of mixing in micro scales. Throughout this research, micromixer is fabricated in UV adhesive-photoresist using maskless grayscale lithography. In order to create 3D microstructures, the traditional photolithography process often requires multiple photomasks to form 3D pattern from several stacked photoresist layers. FEM tools were utilized to assess the mixing efficiency of the presented micromixers versus common T and Zigzag shaped mixers. Both FEM and experimental results prove a 90.8% improvement in the performance of micromixers for low Reynolds numbers at 1 cm versus 8 cm for conventional devices.
