Comment on “Enhancing the output performance of hybrid nanogenerators based on Al-doped BaTiO₃ composite films: a self-powered utility system for portable electronics”, by B. Dudem, L. K. Bharat, H. Patnam, A. R. Mule and J. S. Yu, J. Mater. Chem. A, 2018, 6, 16101

Abstract

This Comment discusses a lack of proof for the relationship of the nanogenerator performance reported in J. Mater. Chem. A, 2018, 6, 16101 to the enhanced piezoelectricity and to the Al-doping of BaTiO3 particles used as the nanogenerator core.
