a method and apparatus for fluid transportation includes a fluid reservoir and a pump that supplies fluid to a microfluidic device . the microfluidic device has an opening and an electrode positioned proximate the opening . the pump pressurizes fluid within the microfluidic device to form a droplet at the opening . when a desired volume of droplet is formed , a potential difference is generated between an electrode and a target plate . the potential difference causes the drop to form a fluid delivery therebetween . the fluid delivery may take many shapes , including a taylor cone or a stream of droplets .
