The principle of needle-free injection based on the reflection of shock waves through microbubble dynamics.

Caption

(A) Dynamics of the electrically induced microbubble, showing the formation, expansion, and shrinking of the microbubble and the shock wave and microjet from the microbubble. (B) Mechanism of the microbubble repetitive mechanical oscillation injection, microjet perforation of the target, shock wave expanding the wound, and the repeated process. (C) Mechanism of shock wave reflection enhancing perforation.
