Nature Solved It First

Biomimicry reveals how nature solved the problem of piercing skin without causing pain. Researchers analyzed the serrated, vibrating proboscis to create instruments that slide into tissue with minimal force. This shift from brute force to mechanical finesse reduces tissue damage significantly. Changing the motion of an injection proves far more effective than just shrinking the tool.
