This article describes a needle-free vaccine injector that works by virtue of the impulse of a moving shock wave.The injector can be used to deliver liquid drugs into soft targets in human body,in a controlled manner,with minimal invasion.The potential human body targets can be skin and soft tissues.The operation of the injector was tested by delivering liquid into human skin samples and gelatin slabs.The penetration depth of liquid in the targets was analyzed and was compared with the depth predicted by reliable theoretical models for similar situations.This new liquid vaccine/drug delivery technique can reduce pain,trauma and contamination,and can offer an important cost-effective solution to needle-flee health-care.
