From: Repetitive regime of highly focused liquid microjets for needle-free injection
Injection depth of the jets in repetitive regime into hydrogel samples with images of injection site. (a) Young’s modulus = 69.5 kPa (b) Young’s modulus = 462 kPa. Error bars are standard deviation of four (69 kPa) and two (462 kPa) measurements. The final penetration depth is established in between 2–3 times of the single jet penetration depth.
