The proposed droplet detection method is based on a media sensitive and volume dependent capacitive sensing principle as sketched in Fig. 1. A free flying droplet is introduced between the two plates of an open plate capacitor driven by an AC voltage. Plate capacitors are sensitive to changes in the geometrical arrangement of the plate electrodes or to alteration of dielectric characteristics [7]. Adispensed droplet, which passes through an open plate capacitor leads to a change of capacity due to its certain dielectric constant
