Mechanical measurements performed included gauge factor, linearity, and zero shift.
However the NC shows a larger gauge factor.
This 85% pure sample has a gauge factor of −22.7 ± 0.5 which is significantly lower than the predicted gauge factor of 57 for a pure (6,5) CNT.
However, this measured gauge factor closely matches the predicted gauge factor for the measured distribution of chiralities in the 85% pure sample.
Thus the average gauge factor of the piezoresistors is calculated as 69.3.
A relatively high gauge factor of 8.5 is reached compared to the commercial metallic strain gauges.
Furthermore, the relative resistivity and the Gauge factor along with the elongation were calculated.
The piezoresistive response was analysed trough the evaluation of the Gauge Factor, K.
The proposed microcantilever deflection sensitivity reveals the gauge factor of approximately equal to 3.78.
The gauge factor of the films is 4.4 and stress sensitivity is 30 Ω/bar.
The maximum piezo-resistivity gauge factor of the sensor is 744.
