Figures

Image of FIG. 1.
FIG. 1.

Schematic diagram of the experimental setup. Thermocouple elements refer to liquid Ga and matching metal wires including constantan, WRe5, WRe26, and GaIn21.5. Heating power of heat souce was kept at 50 W.

FIG. 2.

Measured thermoelectric voltage as a function of temperature difference between Ga and constantan, WRe5, WRe26, and GaIn21.5, respectively. The diameters of WRe5, WRe26, and constantan wires were 0.5 mm, while the diameters of Ga and GaIn21.5 were 1.6 mm, respectively. The accuracy of thermocouples was ±0.5 °C.

FIG. 3.

Measured thermoelectric voltage as a function of temperature difference between (a) Ga-WRe26 thermocouple and Ga with 0.25 wt. % Ga oxides–WRe26 thermocouple, as well as (b) Ga-GaIn21.5 thermocouple and Ga with 0.25 wt. % Ga oxides–GaIn21.5 with 0.25 wt. % Ga oxides, respectively. The diameters of WRe26 wires are 0.5 mm, while the diameters of Ga and GaIn21.5 were 1.6 mm, respectively. The accuracy of thermocouples was ±0.5 °C.

Image of FIG. 4.
FIG. 4.

The Ga with 0.25 wt. % Ga oxides–GaIn21.5 with 0.25 wt. % Ga oxides thermocouple printed on the paper by “hand-written” style with thin film thickness of approximately 50 μm.
