As strange as it sounds, the future of skin care could involve tiny robots powered by changes in humidity. This week, a group of Seoul National University researchers shared their research into creating such devices, inspired by the slow motions of plants.
Currently, when scientists want to know if bacteria are present in
water, they have two main choices. They can take a sample to the lab,
where they'll try growing the suspected bacteria in it, and then count
the number of resulting colonies to determine the concentration. Or,
they can analyze it using expensive lab-based gas chromatography or mass
spectrometry equipment. Now, however, researchers from Seoul National
University have developed a "bioelectronic nose" that could be used on
location, and that is reportedly more sensitive than existing
Despite what our science fiction-fueled imaginations love to be
entertained with, there is more to the field of modern robotics than colossal combat machines or bionic baristas.
Some projects may seem mundane by comparison, yet the results are no
less impressive, especially the ones that enlighten through the process.
Although it took a few trial and error attempts, scientists have
finally created an insect-inspired robot that can jump off of water's
