Abstract
A novel needle-free injection system by electrically induced microbubbles has been developed. First of all, we evaluated the depth of injected reagent for evaluating injection performance. Then, the cavitation-induced shock wave has been focused to magnify the injection performance by semi-spherical reflector. We successfully visualized the shock wave by Shlieren method and succeeded in measuring the pressure of focused shock wave and expansion wave by hydrophone.
