Scientists are using mosquitoes’ sneaky biting ability to make needles less painful for humans. Researchers and engineers at Kansai University in Japan took cues from the mosquito’s needle-like mouth (called its proboscis) to design a minimally invasive, three-pronged needle. The needle also vibrates slightly at about 15 hz., mimicking a real bite that eases the needle into the skin, lessening pain. Tests have proved that the needle worked flawlessly.
