Shear Piezoelectricity in Poly (vinylidenefluoride-co-trifluoroethylene)

Persano, L., Catellani, A., Dagdeviren, C., Ma, Y., Advanced Materials, 28(35), 7633-7639, 2016.


 The intrinsic flexible character of polymeric materials causes remarkable strain deformations along directions perpendicular to the applied stress. The biaxial response in the shear piezoelectricity of polyvinylidenefluoride copolymers is analyzed and their full piezoelectric tensors are provided. The microscopic shear is exploited in single suspended nanowires bent by localized loading to couple flexural deformation and transverse piezoelectric response.
