Compact Biomimetic Hair Sensors Based on Single Silicon Nanowires for Ultrafast and Highly-Sensitive Airflow Detection

“…Despite the important progress, studies on wearable airflow sensors are far lagging behind although airflow sensation is an important function of bodies. Traditional airflow sensors including vane sensors and hot-wire sensors have been widely applied in weather monitoring, exhaust detection, aerospace, and mineral safety. ,− However, they are rigid, bulky, and cumbersome. These constraints obviously hinder their applications in wearable electronics. , …”

Si-containing 3D cage-functionalized graphene oxide grafted with Ferrocene for high-performance supercapacitor application: An experimental and theoretical study

“…The X-ray spectrum of GO (Fig. 7a) shows two characteristic peaks at 2θ= 12.8° (002) and 2θ= 42.5°, which correspond to the interlayer distance of GO sheets and un-exfoliated GO sheets, respectively [95,96]. The mentioned peaks have shifted to 2θ= 25.7° (002) and 2θ= 42.9° in the GO-Amine-SSQ-Fc composite spectrum (Fig.…”

Directly writing flexible temperature sensor with graphene nanoribbons for disposable healthcare devices

“…GNRs derived from this process has the following advantages: (1) remarkably, the hydroxyl and carboxyl endow GNRs the superior dispersity and stability in some polar solvents like water. Compared with another solution processible graphene derivative, Graphene Oxide, [44][45][46][47] GNRs can keep the suspension liquid with low viscosity and good liquidity rather than viscous gel even at high concentration ($10 mg mL À1 ); (2) the nanoscale lateral dimension and the oxygen groups may impart GNRs the certain band gap and local trap levels, and thus yield the high thermo-sensitivity, which would be discussed in more detail later; (3) the unzipping just causes mild damages to the conjunction of GNRs, and the good conductivity gets a retention in some degree, which means that the sensor written by GNRs can work without reduction processing. The excellent solution processability signicantly simplies the fabrication process of sensors, and the thermo-sensitive active material plays an indispensable role in high-precision temperature sensing, both of which are essential to achieve disposable sensors with low cost and high performance.…”
