摘要：

Electrowetting is used to assist the delivery of droplets by a contact method. The electroassisted liquid dispensing technique enables to monitor the drop size via the voltage applied between the tool, i.e., silicon cantilevers and the deposition surface. Voltages ranging from 0 to 210 V are used to deposit water-glycerol drops with diameters and volumes in the ranges of 5-40 mu m and 20 fL-14 pL. The presented results demonstrate that electrowetting-assisted deposition is of special interest for patterning applications requiring large features to be directly and quickly written using a minimum volume of reagents.
