Adv Mater. 2015 Oct 28;27(40):6230-7. doi: 10.1002/adma.201503288. Epub 2015 Sep 16.

Abstract

High-gauge-factor stretchable strain sensors are developed by utilizing a new strategy of thickness-gradient films with high durability, and high uniaxial/isotropic stretchability based on the self-pinning effect of SWCNTs. The monitoring of detailed damping vibration modes driven by weak sound based on such sensors is demonstrated, making a solid step toward real applications.

Keywords: coffee ring effects; high gauge factor; stretchable strain sensors; thickness-gradient films.
