In the version of this article initially published, ref. 80 was cited in the sentence “Work from our laboratory (C.M.L.) has shown that cells adhere and migrate along the electronically active scaffold of mesh electronics.” The correct reference is ref. 9. The error has been corrected in the HTML and PDF versions of the article.
