Correspondingly, we have measured the temperature dependence of similarly doped PVDF thin films for their pyroelectric effect. In this research, we report electrical surface resistivity measurements as a function of temperature of both multiwall and single-wall carbon nanotubes doped PVA thin films, with comparison of the similarities and differences between the two films types.
Consequently, the tension in the actuator increases at the application of the gradient due to the increased mechanical deformations by thermal expansion in the sensor and also the tension due to pyroelectric effect. Figure 15 gives also the corresponding actuator voltage that increases when the gradient is applied.
