Alternating Current Electrohydrodynamic Printing of Microdroplets

Figure 8

Printed droplets under AC voltage with different solution supply rate 𝑄. Solution supply rate and collector motion speed were (a) 𝑄=20 μL/hr, 𝑣_col=6 mm/s; (b) 𝑄=30 μL/hr, 𝑣_col=6 mm/s; (c) 𝑄=50 μL/hr, 𝑣_col=10 mm/s; (d) 𝑄=70 μL/hr, 𝑣_col=10 mm/s. The scale bar is 1000 μm.
