Electromechanical Properties of an Ultrathin Layer of Directionally Aligned Helical Polypeptides

The electromechanical properties of a monomolecular film of poly-γ-benzyl-L-glutamate (PBLG) 15 nanometers thick grafted at the carboxyl-terminal end to a flat aluminum surface were measured. The field-induced change in film thickness, dominated by a large inverse-piezoelectric effect, demonstrates...
