I The fabrication process of the proposed magnetic micropump: ac the PDMS master mold fabrication using the standard photolithographic method, df casting the main body of the micropump which is composed of Ostemer 322 using the PDMS master mold, and gi the total assembly of the magnetic micropump through O2 plasma treatment. The apertures on the PDMS membrane and Ostemer layer were punched by using biopsy punches. II a The photography of the fabricated micropump and the micropump-integrated contact lens. The microscope image of the top view of b the membrane assembly region and c the micro check valve region. The SEM images of the cross-sectional view of the fabricated magnetic micropump including d the membrane assembly region, e the micro check valve region, and f the apertures in the micro check valve
