Popis: Clamping effects in ferroelestastic thin films limits their usefulness for applications such as sensitive mechanical sensors. Here, the authors report on non-local mechanical force induced switching in PbTiO3 thin films by tuning the material to a state of nearly energetically degenerate co-existing domains.
