The effect of pulse wave shape on Taylor cone jetting behavior in electrohydrodynamics micro jet process has been investigated by using the ethyl alcohol solution. The square wave, trapezoid wave and triangular wave with different amplitude have been used in the experiment. The sequential images gathered by the charge-coupled camera combined with a strobe LED have been used to present cone jetting behavior with respect to the time. The shapes of meniscus under different voltage condition have been examined during the jetting process. Results indicated that when the square wave and the trapezoid wave were used the activation of cone jetting and its duration time were closely relied on the amplitude voltage and its duration time, thus this is beneficial for the accurate control of droplet frequency and volume in the drop on demand printing process. However, the introduction of positive amplitude resulted in the delay of the followed cone jetting thus creates error for the jetting uniformity control. The results also indicated that triangular wave was failed to induce the jetting thus this kind of wave shape is not suitable for the jetting control in electrohydrodynamics printing process.
