Patent ID: 8389295

Claim:
A method for transporting at least one droplet of a fluid from at least one reservoir to a target, the method comprising: generating acoustic radiation with an acoustic power level; ejecting a droplet from a first fluid within a reservoir by the generated acoustic radiation; transporting the ejected droplet at a droplet velocity towards a target; applying a predetermined electric field to the droplet and the target; generating a dipole within the droplet by the applied electric field; and attracting the droplet to the target by an interaction between the dipole and the target; wherein the process for applying a predetermined electric field to the droplet and the target is performed without substantially affecting the droplet velocity; wherein the process for attracting the droplet to the target includes increasing, by the applied predetermined electric field, a likelihood that the droplet does not splash or bounce on arriving at the target; wherein a first direction of the applied electric field and a second direction of the droplet velocity are opposite to each other.
