Researchers
develop optical displays from water and air
14.06.2012
For many
years, scientists have been pursuing ways to mimic the perplexing capability of
the lotus leaf to repel water. Lotus leaves hate water so much that droplets
effortlessly roll off the surface, keeping it clean from dirt. Now an
international team of researchers led by Aalto University have come up with an
entirely new concept of writing and displaying information on surfaces using
simply water.
They
exploit the unique way a trapped layer of air behaves on a lotus-inspired
dual-structured water-repelling surface immersed under water.
