The DC resistance measurements with carried out in air at humidity of 40 % and vacuum, evacuated under 6x10 Pa, by applying the voltage of -5 to -i-5 V. The electrode was A1 plate with 8x8x0.005 mm. In order to investigate temperature dependence on the conductivity, the DC measurement was performed in the temperature range 300 to 393 K in vacuum. Also, the conductivity to the temperature was measured after heating to 393 K in vacuum.

By synchronizing the relative difference of resistance measurements with the tensile force measurements applied to the sensor yarn placed onto a tensile bench and tested at 50 mm/min, the two values can be represented on the same figure (Fig. 17.8) for a range of 1% of the sensor deformation in length. The core yam tested... 

The effective resistance offered by a given conductor to radio frequencies is considerably higher than the ohmic resistance measured with direct current. This is because of an action known as the skin effect, which... 

In Figure 8.13 the mesogen and compound types are specified. The results of surface resistance measurements with in situ polymerized films from these compounds are tabulated in Table 8.2.
