Nested Wrinkles in Skin
Wrinkles occur on scales varying from a few nanometers
(in thin films) to hundreds of kilometers (on the surface
of the earth), in a variety of natural phenomena (see
above). Typically wrinkling, buckling and other mechanical
instabilities have been treated as a nuisance to be
avoided rather than an exquisite pattern to be exploited.
However, once they are understood, it is possible to
control and even use them. Our recent work focuses on
one such attempt to understand, control and use wrinkling
patterns.
