In the field of human health care, nearly 12 billion injections are administered annually for medical purposes. From conventional hypodermic needles to needle-free jet injectors, technology advancement has played a pivotal role in the creation of a noninvasive way of drug delivery. However, as much as needle-free jet injectors offer numerous advantages over conventional hypodermic needles, there are still major drawbacks to its mechanism. To overcome the issues that existing jet injectors bring, a similar device that employs a piezoelectric actuator to generate high-speed microjets is proposed. This piezoelectric-based mechanism can accelerate fluid to velocities sufficient for skin penetration. Hence, the fact that piezoelectric device are easily controllable makes it ideal and feasible to attain precise injection.
