This paper evaluates a needle-free injector using electrically induced bubbles. For a minimally invasive injector, the configuration of the bubble reservoir, which is at the tip space of the bubble injector, must be optimized because the invasiveness depends on the breakdown distance of the electrically induced bubble.
