“…A simulation was carried out in ANSYS by numerical solving of thermal and electric conduction equations [23]. Material properties with appropriate values were assigned to each part of the WSN node, as described in [10]. Joule heating, Seebeck, Peltier, and Thomson effects are taken into account simultaneously, while the radiation effect is neglected [24,25].…”

“…Several analytical models with different level of complexity are available for the thermal and electrical characterization of the TEG [14][15][16][17][18]. Although proven to be accurate for standalone devices, the models cannot take into account complex thermal conditions when the TEG is built into the WSN node [10,11]. The complexity of the analysis increases even further by including non-stationary thermal effects, like air flow over the WSN node.…”

“…the temperature difference between the hot and cold junctions of two materials to produce voltage. In our previous works, we have shown how aluminum core printed circuit boards (PCBs) can be used to improve performances of the WSN node [9], and established guidelines for choosing an appropriate TEG [10][11][12]. However, these considerations were limited to the thermal steady-state case, where there is a fixed ambient temperature, and no air flow over the WSN node.…”

This paper considers the effects of the ambient temperature and unducted air flow on the voltage generated by a thermoelectric generator used to power wireless sensor network node. Structure of the node is simulated using a fully coupled numerical electro-thermal model with convective correlations. Results show that the effect of the ambient temperature is negligible as long as the temperature difference between the hot surface of the node and the ambient is maintained. For natural convection, voltage dependence on the temperature difference can be determined from the open circuit conditions and this can be used to approximate the load conditions. For forced convection, an increase rate of the generated voltage is governed by the thermal resistance of the heatsink and characteristic parameters of the thermoelectric generator.

“…In spite of moderate performance, oxide TE modules have the potential to replace batteries as a power source for sensors operating at high temperatures in oxidizing and mild reducing atmospheres, and as such also enable wireless transfer of data from the sensors. [1][2][3][4] Oxide TE modules may also be used at high temperatures as heat flux monitors, which is highly relevant in the process industry. 5 Several oxide materials with p-type electrical conductivity have been reported, including Ca 3 Co 4Àx O 9+d (CCO), which shows the highest performance.…”

Here, we present the performance of a thermoelectric (TE) module consisting of n-type (La 0.12 Sr 0.88 ) 0.95 TiO 3 and p-type Ca 3 Co 4Àx O 9+d materials. The main challenge in this investigation was operating the TE module in different atmospheric conditions, since n-type has optimum TE performance at reducing conditions, while p-type has optimum at oxidizing conditions. The TE module was exposed to two different atmospheres and demonstrated higher stability in N 2 atmosphere than in air. The maximum electrical power output decreased after 40 h when the hot side was exposed to N 2 at 600°C, while only 1 h at 400°C in ambient air was enough to oxidize (La 0.12 Sr 0.88 ) 0.95 TiO 3 followed by a reduced electrical power output. The module generated maximum electrical power of 0.9 mW ($ 4.7 mW/cm 2 ) at 600°C hot side and DT $ 570 K in N 2 , and 0.15 mW ($ 0.8 mW/cm 2 ) at 400°C hot side and DT $ 370 K in air. A stability limit of Ca 3 Co 3.93 O 9+d at $ 700°C in N 2 was determined by in situ high-temperature x-ray diffraction.

“…2 The TE module will generate a voltage difference when temperature difference exists across the module, thereby producing electricity in external circuit. 3 Note that commercial thermoelectric modules are widely applied to energy harvesting applications such as photovoltaic power generation system, [4][5][6] vehicle exhaust, [7][8][9][10][11] human body heat recovery, 12 residential heating system, [13][14][15] biomass stove and furnace, 16,17 wireless sensors, 18,19 and processing chips. 20,21 For large-scale applications, Zhang et al 5 evaluated the efficiency of hybrid systems with different photovoltaic (PV) cells including crystalline silicon PV, silicon thin-film PV, polymer PV, and copper indium gallium selenide PV.…”

This article presents an effective method for harvesting waste heat from a household cooktop. The energy‐harvesting module contains a thermoelectric (TE) module, heat pipe module, and phase change material (PCM). The effects of TE modules, cooling mediums (air, water, and paraffin), and heat sink configuration and arrangement on the overall performance of the energy harvesting module are examined experimentally. It is found that the cooling process on the cold side of TE plays an essential role on the output voltage and system performance. By adding an air‐cooled heat sink, both output voltage and temperature difference can be moderately improved. Yet using a water‐cooled heat sink can improve the output voltage by about four times higher. Furthermore, the output voltage can be further promoted by using more efficient thermoelectric module. It appears that fewer fins incorporated with the PCM container filled with paraffin shows the optimal energy harvesting performance. Additionally, the recharging time for the full, medium, and low flame operation is tested with 3, 4, and 15 minutes, respectively, and the maximum recharging power of 7.25 W can be achieved with the highest energy storage of 523 mAh after operating 30 minutes.
