Aiming at the great challenge to fabricate flexible pressure array sensors with high sensitivity and large working range simultaneously
a pressure sensor with high sensitivity(3.29 kPa
-1
)and a large working range(0~45 kPa)using the air-laid paper is developed. The paper is soaked with the mixture composed of the graphene-carbon nanotubes and polydimethylsiloxane(PDMS).The paper-based sensing layer is sensitive to the pressure
convenient for electrical connecting
and easy to be laser cut into arrays.Based on the superior performance
the sensor can be used to detect not only the vigorous but also the subtle human motions.The advantages of the flexible high sensitivity
the facile fabrication process
low cost
eas
y electrical connecting
show the potential applications in the wearable sensor field and intelligent robots.
