Charge-induced reversible bending in nanoporous alumina-aluminum composite

(author unknown)



Chuan Cheng and A. H. W. Ngan

Upon electrical charging, reversible bending was found in nanoporous anodic alumina-aluminum foil composites, as directly observed by an optical microscope and detected by in situ nanoindentation. The bending is thought to be the result of charge-induced surface stresses in the nanoporous alumina. ... [Appl. Phys. Lett. 102, 213119 (2013)] published Fri May 31, 2013.
