High-strain sensors based on ZnO nanowire/polystyrene hybridized flexible films.

A type of strain sensor with high tolerable strain based on a ZnO nanowires/polystyrene nanofibers hybrid structure on a polydimethylsiloxane film is reported. The novel strain sensor can measure and withstand high strain and demonstrates good performance on rapid human-motion measurements. In addition, the device could be driven by solar cells. The results indicate that the device has potential applications as an outdoor sensor system. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
