The emergence of a domain wall property that is forbidden by symmetry in bulk can offer unforeseen opportunities for nanoscale low-dimensional functionalities in ferroic materials. Here, we report that the piezoelectric response is greatly enhanced in the ferroelastic domain walls of centrosymmetric tungsten trioxide thin films due to a large strain gradient of 10<sup>6</sup> m<sup>-1</sup>, which exists over a rather wide width (~20 nm) of the wall. The interrelationship between the strain grad ...[more]
