Abstract

A process for sorting materials using material-selective electroadhesive grippers is disclosed. At least one of an electroadhesive surface or a plurality of articles is manipulated such that multiple ones of the plurality of articles are at least intermittently proximate the electroadhesive surface. Voltage is applied to one or more electrodes in the electroadhesive surface to thereby cause the electroadhesive surface to selectively adhere to a subset of the plurality of articles based on the subset of the plurality of articles having different material properties than others of the plurality of articles. While the voltage is applied, the electroadhesive surface is moved with respect to the others of the plurality of articles to thereby separate the subset of the plurality of articles from the others of the plurality of articles.
