The experimental data includes measurements of piezoelectric strain coefficients, permittivity and energy harvesting figure of merit for sandwich layer porosity of 50 and 60 vol.% and varying porous layer thickness. The data from the finite element modelling includes calculated effective piezoelectric and dielectric properties for barium titanate with sandwich layer porosity of 0 to 60 vol.% and porous layer relative thickness of zero (i.e. no porous layer) to one (i.e. no dense outerlayers), as well as detailing the fraction of material poled due to the distribution of porosity throughout the complex structure. 2017 University of Bath public RightsHolder University of Bath Seventh Framework Programme https://doi.org/10.13039/501100004963 320963 NEMESIS - Novel Energy Materials: Engineering Science and Integrated Systems Experimental data was obtained from measuring material properties of barium titanate with a high porosity layer sandwiched between dense outerlayers. Modelled data was obtained from finite element analysis of porous sandwich layer barium titanate with varying layer porosity and porous layer relative thickness.
