  Nanopores in solid state membranes are a tool able to probe nanofluidic
phenomena or can act as a single molecular sensor. They also have diverse
applications in filtration, desalination or osmotic power generation. Many of
these applications involve chemical, or hydrostatic pressure differences, which
act on both the supporting membrane and the ion transport through the pore. By
using pressure differences between the sides of the membrane, and an
alternating current approach to probe ion transport, we investigate two
distinct physical phenomena: the elastic deformation of the membrane through
the measurment of strain at the nanopore, and the growth of ionic current
rectification with pressure due to pore entrance effects.
