“…Besides, GNP with concentration in the range of 0.025%-0.10% has zero impact on the flexural strength. [74][75][76][77][78][79] Furthermore, the sensor mortar with high dosage (2%) of GNP has a higher impact load resistance under ultimate loading conditions. 75 Moreover, increasing the dosage of GNP increases the hardness of the cement composite and decreases the abrasion over the cement composites by 71%.…”

“…Indeed, a combination of CNTs (one-dimensional) and GNPs (two-dimensional) that have different geometric shapes can act as nanoreinforcement through the bridging of nanoscale cracks and/or their deviation and branches [52]. Crack bridging, deflection, and branching are known to be important sources of strengthening and toughening in CNM-reinforced composites, especially in those with brittle matrix [53][54][55][56][57][58]. In CNM-reinforced composites, crack bridging is typically assured by CNTs, while GNPs often increase the energy required to open nanocracks by deviating their paths and, consequently, increase the total fracture surface and prevent their degeneration into microcracks (Fig.…”

“…20−23 Voice signals contain rich character information on humans and are easy to use, so people can use voice signals to make and realize accurate commands. At present, the main sensors currently used for speech recognition are capacitive sensors, 24,25 piezoresistive sensors, 26,27 piezoelectric sensors, 28−30 and triboelectric sensors. 31−33 However, some components in capacitive and piezoresistive sensors, such as conventional commercial microphones, rely on battery charging and are vulnerable to environmental noise.…”

“…Nowadays, there are two main methods of human–machine interaction: voice–machine interaction and gesture–machine interaction. Voice signals contain rich character information on humans and are easy to use, so people can use voice signals to make and realize accurate commands. At present, the main sensors currently used for speech recognition are capacitive sensors, , piezoresistive sensors, , piezoelectric sensors, and triboelectric sensors. However, some components in capacitive and piezoresistive sensors, such as conventional commercial microphones, rely on battery charging and are vulnerable to environmental noise. On the other hand, piezoelectric sensors have complex structures, troublesome manufacturing process and short working frequency ranges.…”
