Question

as you have likely experienced, mosquitos often bite into human skin without detection. researchers have learned that mosquitos have moving mouthparts that allow them to pierce skin with little, if any, pain to the skin. engineers used this knowledge to develop a medical needle that works in a similar way. the needle penetrates skin like a mosquito, and the result is a painless injection. these are just a few examples of biomimicry at work. it’s an exciting and innovative field that offers possible solutions with minimal negative impact. 4. how is biomimicry being used to develop painless injections?

Explanation:

Researchers observed that mosquitoes' moving mouth - parts allow them to pierce skin with little pain. Engineers applied this knowledge to develop a medical needle that penetrates skin like a mosquito, resulting in painless injections.

Answer:

Engineers used the knowledge of mosquitoes' moving mouth - parts that can pierce skin with little pain to develop a medical needle that penetrates skin in a similar way for painless injections.
