See linked picture for basic design. This is an adaptively designed needle that has progressively harder and smaller fractal branches so that the outer softer layers of the tube gently push skin out of the way. This could be designed down to the molecular level so that you could, if you were gentle enough just sneak stuff under the skin without breaking its integrity.
