Vanadium oxide macroscopic fibers (see Figure) are obtained by an extrusion process. The fibers consist of nanoscopic ribbons with a preferential orientation and a longitudinal Young's modulus of around 15 GPa. As well as showing high sensitivity, the fibers reversibly cycle between insulating and semiconducting upon exposure to alcohol vapor sources, with signature responses to different alcohols.
