Redox Activation of a Polyaniline-Coated Cantilever: An Electro-Driven Microdevice Parts of this research are supported by The Israel Ministry of Science and the Israel Science Foundation. M. Lahav gratefully acknowledges the support of The Clore Israel Foundation Scholars Programme.

Bent by oxidation! A polyaniline (PAn, blue) coated cantilever acts as an electro-driven microdevice. Reversible oxidation/reduction of the PAn results in reversible deflection of the cantilever (see picture) originating from the electrostatic repulsion of the charged polymer chains of PAn2+ (green).
