A stretchable carbon nanotube strain sensor for human-motion detection

TL;DR: This review covers the smart designs of structural materials inspired by natural materials and their utility in the construction of flexible devices, and summarizes structural materials that accommodate mechanical deformations, which is the fundamental requirement for flexible devices to work properly in complex environments.

TL;DR: In this paper, a strain sensor was fabricated from a polymer nanocomposite with multiwalled carbon nanotube (MWNT) fillers, and the piezoresistivity of the sensor was investigated based on an improved three-dimensional (3D) statistical resistor network.

TL;DR: The authors leverage the variations of the interlayer distance in Ti3C2 under external pressure to devise a piezoresistive sensor which can detect human being’s subtle bending-release activities and other weak pressure.

TL;DR: Wearable tactile sensors as mentioned in this paper can collect mechanical property data of the human body and local environment, to provide valuable insights into the human health status or artificial intelligence systems, thus, emerging as a promising development direction toward the Internet of Things (IoT) applications.

TL;DR: Water-stimulated enhanced catalytic activity results in massive growth of superdense and vertically aligned nanotube forests with heights up to 2.5 millimeters that can be easily separated from the catalysts, providing nanotubes material with carbon purity above 99.98%.

TL;DR: This dense carbon-nanotube material is advantageous for numerous applications, and here it is demonstrated its use as flexible heaters as well as supercapacitor electrodes for compact energy-storage devices.

TL;DR: The manufacture of printable elastic conductors comprising single-walled carbon nanotubes (SWNTs) uniformly dispersed in a fluorinated rubber is described, which is constructed a rubber-like stretchable active-matrix display comprising integrated printed elastic conductor, organic transistors and organic light-emitting diodes.

TL;DR: A simple approach to high-performance, stretchable, and foldable integrated circuits that integrate inorganic electronic materials, including aligned arrays of nanoribbons of single crystalline silicon, with ultrathin plastic and elastomeric substrates.
