Abstract

original image

A nanoindenter tip, as a tool to characterize electrical energy generation from piezoelectric thin films, is presented by Madhu Bhaskaran and co-workers on page 2251. For the first time, such direct interactions at the nanometer scale are used for controlled in situ characterization of the voltage and current generation of piezoelectric thin films. Quantitative results demonstrate that nanopatterning yields an improved materials platform for integrated micrometer-scale energy-harvesting systems.
