Carbon Nanotubes Based Piezoresistive Pressure Sensor
Piezoresistive sensors are the sensors which convert the pressure applied into the change in the resistance. It
involves the silicon substrate that bends with the applied pressure that gives the overall change in the resistance. Nowadays,
although piezoresistive pressure sensor has wide range of applications, the materials with which it is formed makes this
pressure sensor to act more effectively with high sensitivity. This paper describes the relative comparisons of different
materials with respect to the carbon nanotubes and also elaborates the working mechanism of this carbon nanotubes
piezoresistive pressure sensor.
