3.4 thermal conductivity kc at a point fixed in a medium with a temperature field. scalar quantity k characterizing the ability of the medium to transmit heat through a surface element containing that point: ‘p = —k grad 7’, where is the density of heat flow rate and 7’ is thermodynamic temperature
Note I to entry: Pt appears primarily in Fourier’s Law for heat conduction. This value is dependent on temperature, Thermal resistivity is gwen by the reciprocal of thermal conductivity.

4 Testing method
4.1 General experimental apparatus
The general principle for the test set-up to measure the amount of power generation from thermoelectric devices, especially focusing on flexible thermoelectric devices, is described. In general, the thermoelectric device generates electric energy due to the temperature difference between one surface of the device and the other surface. Hence, in order to characterize the performance of the device, the temperature of both the cooling and heating sides In an experimental set-up should be maintained consistently. The general schematic diagram of the thermoelectric device, including the experimental set-up to measure the generated power, is illustrated in Figure 1. An explanation about the commonly used formulas related to the thermoelectric device and the experimental set-up is also included. The basic principle of the measurement method for both rigid and flexible devices is the same but the experimental apparatus can be different due to the flexibility of the flexible thermoelectric device. In order to use the advantage of a flexible thermoelectric device as well as to investigate its limitations, the performance of the flexible thermoelectric device should be determined under the bending condition.IEC 62830-5 pdf download.
