We used EWOD chip to realize microfluidic patterning of propylene carbonate. The motivation in patterning of microfluidic is that, the digital microfluidic system can have expected to be used in printing technologies. As we know the existing printing technologies may easily cause mother's mold damage and short life. By using the parallel plate EWOD system, the propylene carbonate liquid was successfully patterned into different English alphabets.
