Fig. 1: Overview and numerical characterization of drug delivery microsystem based on microexplosion shockwave injection.
a Schematic diagram of the structure and characteristic dimensions of the explosive shockwave-based drug delivery microsystem. b An implantable targeted drug delivery microsystem performs shockwave drug injection in the gastrointestinal tract, brain, and curved or flexed area of blood vessels. c Variation in effective stress at different points on the shell under shockwave and the relation between the thickness t of the tubular shell and the maximum stress. The red circle indicates the final manufacturing selection of the shell thickness value
