"Corals in the Ocean are made up of coral polyps, a small soft creature
with a stem and tentacles, they are responsible for nourishing the
corals, and aid the coral's survival by generating self-made currents
through motion of their soft bodies.
Scientists from WMG at the University of Warwick, led by Eindhoven
University of Technology in the Netherlands, developed a 1cm by 1cm
wireless artificial aquatic polyp, which can remove contaminants from
water. Apart from cleaning, this soft robot could be also used in
medical diagnostic devices by aiding in picking up and transporting
specific cells for analysis.
In the paper, 'An artificial aquatic polyp that wirelessly attracts,
grasps, and releases objects' researchers demonstrate how their
artificial aquatic polyp moves under the influence of a magnetic field,
while the tentacles are triggered by light. A rotating magnetic field
under the device drives a rotating motion of the artificial polyp's
stem. This motion results in the generation of an attractive flow which
can guide suspended targets, such as oil droplets, towards the
artificial polyp."
