TL;DR: A multi-functional respiratory monitor has been built under the stimuli of the human breath and exhibits high current response to small perturbations induced by temperature variations, mechanical interactions, and relative humidity changes, thereby achieving an environmental perceptibility.
Abstract: Controllable and sensitive perception of environmental changes is essential for the development of smart material and device systems. Herein, a multi-stimuli sensitive responsor has been fabricated on the base of the established double-helix core-sheath graphene-based microfibers (GFs). By combining the tunable conductivity and mechanical robustness of GF coated with graphitic carbon nitride (GF@GCN), a fibriform smart environmental responsor (SER) is prepared by water-assisted GFs-twisting strategy, which can accordingly present conductive state-dependent current responses upon exposure to a variety of stimuli. More importantly, this SER exhibits high current response to small perturbations induced by temperature variations, mechanical interactions, and relative humidity changes, thereby achieving an environmental perceptibility. Based on this finding, a multi-functional respiratory monitor has been built under the stimuli of the human breath.

23 Jan 2004TL;DR: In this paper, the authors proposed a method for detecting displacement, impact, stress, and/or strain in carbon nanotubes, which relies on mechanically induced electronic perturbations within the carbon-nanotubes to detect and quantify such stress and strain.
Abstract: The present invention is directed toward devices comprising carbon nanotubes that are capable of detecting displacement, impact, stress, and/or strain in materials, methods of making such devices, methods for sensing/detecting/monitoring displacement, impact, stress, and/or strain via carbon nanotubes, and various applications for such methods and devices. The devices and methods of the present invention all rely on mechanically-induced electronic perturbations within the carbon nanotubes to detect and quantify such stress/strain. Such detection and quantification can rely on techniques which include, but are not limited to, electrical conductivity/conductance and/or resistivity/resistance detection/measurements, thermal conductivity detection/measurements, electroluminescence detection/measurements, photoluminescence detection/measurements, and combinations thereof. All such techniques rely on an understanding of how such properties change in response to mechanical stress and/or strain.
