Alternating Current Electrohydrodynamic Printing of Microdroplets

Figure 6

Printed droplets under AC voltage with different applied AC voltage frequency 𝑓_app. AC voltage frequency and collector motion velocity were (a) 𝑓_app=10 Hz, 𝑣_col=4 mm/s; (b) 𝑓_app=30 Hz, 𝑣_col=10 mm/s; (c) 𝑓_app=50 Hz, 𝑣_col=10 mm/s; (d) 𝑓_app=70 Hz, 𝑣_col=10 mm/s. The scale bar is 1000 μm.
