Current research about resistive sensors is rarely focusing on improving the strain range and linearity of resistance–strain dependence. In this paper, a bi‐sheath buckled structure is designed containing buckled carbon nanotube sheets and buckled rubber on rubber fiber. Strain decrease results in increasing buckle contact by the rubber interlayer and a large decrease in resistance. The resulting...
A highly stretchable, resistive strain sensor composed of a bi‐sheath structure is described by Jianning Ding, Linqi Shi, Zunfeng Liu, and co‐workers in article number 1702134. Buckles of a carbon nanotube sheath contact with one another under compression of an underlying buckled elastomer sheath, which is co‐axially coated on a rubber fiber. Stretching separates the buckles, resulting in linear increase...
Self-welded double-wall and multi-wall carbon nanotube (DWCNT and MWCNT) bridges were used for the first time as nano-scale piezoresistors to monitor vibration and deformation of silicon cantilever beams. The CNTs were grown using low-pressure metal-catalyzed chemical vapor deposition technique between silicon-on-insulator posts situated over cantilever beams such that when the beams were deformed,...
Near-field microwave probes were developed and used to image electromagnetic properties of materials with spatial resolutions only limited by the probe aperture size, signal-to-noise ratio and not by the Abbe barrier. The price of this "super" resolution is point-by-point scanning of the sample that makes it slow and requires additional mechanisms to control the probe-to-sample distance...
