"reliably detect variations in humidity in settings that included industrial exhaust and the air surrounding human skin... Narrow, scroll-like passages within a camel’s nose create a large surface area, which is lined with water-absorbing mucus... porous polymer network. On it, they placed moisture-attracting molecules called zwitterions to simulate the property of mucus to change capacitance as humidity varies"
