Applications of ferroelectric ceramics, ranging from components for sensors, memory devices, microelectromechanical systems and energy convertors, all involve planar and rigid layouts. The brittle nature of such materials and their high temperature processing requirements limit applications to devices that involve only very small mechanical deformations and narrow classes of substrates. Here, we report a strategy for integrating nanoribbons of one of the most widely used ferroelectric ceramics, lead zirconate titanate, in ‘wavy’ geometries, on soft, elastomeric supports to achieve reversible, linear elastic responses to large strain deformations (i.e. stretchable properties), without any loss in ferroelectric or piezoelectric properties. The results suggest new design and application possibilities in memory devices.
