Study Notes

Biomimicry and Painless Needles

Biomimicry, the process of using nature's designs to solve human problems, can create medical tools like painless needles.
Mosquito bites are painless, providing a potential model for creating needles that do not hurt.
Mosquitoes have thin, sharp mouths shaped like tiny needles, as thin as a human hair, minimizing nerve stimulation.
The needle-like mouths of mosquitoes have small, saw-like edges (serrations), making contact with only a few points on the skin, further reducing pain.
The lack of pain associated with mosquito bites is crucial for their survival. If they caused as much pain as injections, their survival rate would likely be reduced.
Research on the structure of mosquito mouths is informing the design of new needles to reduce pain during injections.
These new, pain-free needles are already in use in some contexts and may become commonplace in the future.
