Table 1

Sensitivity and percentage of decrease in DC resistance for pure CNT, pure graphene, and CNT-graphene composite sensor.

Sensor type	External applied pressure; (kNm^−2)	Percentage decrease in resistance; (%)	Sensitivity; (m^2/kN)
Pure CNT	0 to 0.183	80	4.37
Pure graphene	0 to 0.183	63.24	3.44
CNT-graphene composite	0 to 0.183	70.32	3.82
