Multifunctional wearable strain/pressure sensor based on conductive carbon nanotubes/silk nonwoven fabric with high durability and low detection limit

High-Sensitive Wearable Strain Sensors Based on the Carbon Nanotubes@Porous Soft Silicone Elastomer with Excellent Stretchability, Durability, and Biocompatibility

“…The introduction of CNTs greatly increases the micro-/nanometer cooperative roughness of the elastomer surface, thereby enhancing the hydrophobicity of the substrate. From the Raman spectra (Figure S4b), two obvious characteristic peaks of CNTs@PSSE can be observed at 1348.24 and 1578.22 cm –1 , corresponding to the D-band (the carbon structure disorder) and G-band (the sp2-hybridized carbon atoms) of CNTs, which confirm the successful decoration and no damage of CNTs …”

“…The piezoresistive strain sensor has attracted broad attention due to the advantages of simple architecture and easy manufacture. , Hybridizing conductive fillers with stretchable substrates provides a suitable strategy to endow the strain sensor with good wearability and deformability. − The carbon-based materials [e.g., graphene (Gr), carbon nanotubes (CNTs), and carbon black (CB)] are usually used as conductive fillers due to their superiorities of low toxicity, high stability, and good conductivity. − As for the substrate, various elastomers with the geometry of the fiber structure, , crumpled/wrinkled structure, , and porous structure are developed to improve the strain sensing performance. Among them, silicone-based elastomers [such as polydimethyl siloxane (PDMS)] with low hysteresis, chemical inertness, and low cost are typically used to assemble strain sensors .…”

Hydroxyapatite coatings: a critical review on electrodeposition parametric variations influencing crystal facet orientation towards enhanced electrochemical sensing

“…171,172 The detection of gaseous components from industrial and manufacturing processes, 173,174 and use as biosensors for glucose, peroxidase and protein estimation [175][176][177][178] are some of the incredible applications of sensors. The materials constituting a sensor can include semiconductor metal oxides [179][180][181][182] and carbon-based materials 183,184 with functionality ranging from mechanical stimuli [185][186][187][188][189][190][191] to environmental monitoring. 192,193 The quantitative detection and sensing of gaseous pollutants is vital in the industrial and manufacturing arena to safeguard human health.…”

Absorption Dominated Directional Electromagnetic Interference Shielding through Asymmetry in a Multilayered Construct with an Exceptionally High Green Index

“…With the recent surge in the usage of electronic devices, − electromagnetic interference (EMI) poses a serious threat. Unwanted electromagnetic (EM) waves not only interfere with the normal functioning of electronic components, but certain studies suggest that it is a serious threat to human health. , EMI shielding is a technique to block undesired EM radiation by designing a material that either reflects or absorbs the incoming EM waves.…”
