“…This solution sacrifices the convenience and processing power of a commercial sensor node in exchange for energy saving. A thermoelectric power generation device based on solar irradiation heating, and using a commercial TEG, GM-200-127-14-16 from European Thermodynamics, is described in [4]. The experimental results show that one TEG module is able to generate 4.7mW power for wireless sensor nodes or other low power applications at 3.75!104 lux illumination in full daylight, but the proposed generator has not been proven to actually power a sensor node.…”

Abstract-The feasibility of using thermal energy harvesting to power a wireless sensor node for temperature monitoring of industrial devices is explored and evaluated in this paper. The thermal energy harvesting equipment and energy conversion circuit have been designed and fabricated. A series of experiments with various sleep periods for the sensor node are undertaken. The experimental results show that the thermal energy harvesting equipment and energy conversion circuit are able to power a commercial wireless node when the sleep period of the node is more than 16s, equating to a duty cycle of 5.4%. The results also indicate that the wireless sensor network based on the proposed autonomous wireless sensor node can monitor the industrial device temperature successfully.

et al. 2015

Abstract:A thermoelectric generator (TEG) device which uses solar energy as heat source would achieve higher efficiency if there is a higher temperature difference between the hot-cold ends. However, higher temperature or higher heat flux being imposed upon the hot end will cause strong thermal stress, which will have a negative influence on the life cycle of the thermoelectric module. Meanwhile, in order to get high heat flux, a Fresnel lens is required to concentrate solar energy, which will cause non-uniformity of heat flux on the hot end of the TEG and further influence the thermal stress of the device. This phenomenon is very common in solar TEG devices but seldom research work has been reported. In this paper, numerical analysis on the heat transfer and thermal stress performance of a TEG module has been performed considering the variation on the power of the heat flux being imposed upon the hot-end; the influence of non-uniform high heat flux on thermal stress has also been analyzed. It is found that non-uniformity of high heat flux being imposed upon the hot end has a significant effect on the thermal stress of TEG and life expectation of the device. Taking the uniformity of 100% as standard, when the heating uniformity is 70%, 50%, 30%, and 10%, respectively, the maximum thermal stress of TEG module increased by 3%, 6%, 12%, and 22% respectively. If we increase the heat flux on the hot end, the influence of non-uniformity on the thermal stress will be more remarkable.

IntroductionMicro-energy harvesting has been widely studied because of the development of wireless sensor networks. Various energy harvesting techniques, such as solar energy, thermal energy, and vibration energy have been investigated to eliminate dependence on batteries or wires [1][2][3][4][5]. The electromagnetic, electrostatic, and piezoelectric transition mechanisms are the main methods for harvesting vibration energy. In particular, piezoelectric vibration energy harvesting has received significant attention for its high power density, simple structure, and ability to operate without producing pollution [6].A piezoelectric energy harvesting system mainly consists of a mechanical structure and interface circuits. With regard to the mechanical structures in such systems, cantilever beams with patches of piezoelectric materials have been extensively investigated [7,8]. The performance of the energy generated by piezoelectric elements with harmonic excitations has been studied widely. Recently, flow-induced piezoelectric energy harvesting has gained much attention. Some of the trends in piezoelectric energy harvesting are multi-directional wideband technology [9] and flow-induced or impact-induced piezoelectric energy harvesting [10]. In these systems, the electricity generated by piezoelectric cantilever beams is not sinusoidal. Meanwhile, the mechanical structures for collecting multi-direction energy and flow-induced piezoelectric energy have been widely investigated. Experiments on many mechanical structures under different conditions have been performed to evaluate the performance of different structures. With regard to interface circuits, the standard interface circuit, series synchronized switch harvesting interface circuit (S-SSHI), parallel synchronized switch harvesting interface circuit (P-SSHI), and synchronized charge extraction interface circuit (SCE) have been analyzed in detail, and all involve standard sinusoidal equivalent sources [11][12][13]. However, the performance of different interface circuits with a non-standard sinusoidal equivalent source has been minimally investigated. Many experiments have been performed in ideal laboratory environments where piezoelectric elements were subjected to harmonic excitations; thus, numerous analyses involving sinusoidal signals have been made.
