Camels have a renowned ability to survive on little
water. They are also adept at finding something to drink in the
vast desert, using noses that are exquisite moisture detectors. In
a new study in ACS Nano, researchers describe a humidity sensor
inspired by the structure and properties of camels’ noses. In
experiments, they found this device could reliably detect
variations in humidity in settings that included industrial exhaust
and the air surrounding human skin.
