“…Thermoelectric (TE) devices can convert heat into electricity via the Seebeck effect or use electrical power to establish a temperature difference across the device and provide cooling (Peltier effect). This technology has been successfully in use for many years in aerospace missions and cooling applications , and recently has gained attention for power generation in other areas where heat is available, such as industries, , the human body, , combustion engines, − or even in volcanos . TE systems have several advantages that are difficult to overcome by other technologies; for example, they are environmentally friendly, silent, and compact and have no moving parts (free of maintenance).…”

Thermoelectric (TE) devices can convert heat to electrical power or use electrical power to generate a temperature difference. Their characterization is essential to develop devices with higher efficiency. Impedance spectroscopy models have been developed in the last few years, and it has become a highly advantageous method for TE system characterization. Recently, it has been shown that this technique can also be used to determine internal thermal contacts (between the TE legs and the metallic strips that connect them and between the metallic strips and the outer layers). Here, we developed for the first time a spreading−constriction expression which does not assume cylindrical geometry. The enhanced model is also used to characterize four TE devices from different manufacturers, highlighting overestimations up to 13% when the previous cylindrical approximation is used. A code is provided in the Supporting Information ready to fit the experimental data. This study positions impedance spectroscopy as a powerful tool to detect and monitor issues during manufacturing or operation of TE devices, which typically occur at the contacts.

“…In this experiment was performed by laying a heat sink in a duct of rectangular shaped fin's with insulated surface-area. Then the "Pressure, Temperature nearby the Inlet-outlet of the duct are monitored" [12], and power is required to maintain a certain temperature at the heatsinks values are generated and tabulated in Table 1 base surface under these conditions, the corresponding heat released by the heat sink device and Pressure loss across the duct can be estimated. The purpose of the application was to study typical experiments.…”

This paper focuses on modelling of Heat sink for thermoelectric Generator which requires a heat sink to achieve high electrical output efficiency. Thermoelectricity refers to a phenomenon in which a temperature gradient causes a flux of the electric charge. This work deals with models of different geometries, based on heatsinks designed to improve thermoelectric generator performance. The thermo-electric generator efficiency increased with the temperature gradient ΔT with the cooling junction. Here comparing of the conventional and analytical heat sinks, from analytical heat sinks, we can choose the beat efficient heat sink for thermoelectric generator high performance. The heat sink, whose device is to be improved by the geometry of the Heat sink models designed with different shapes of Fins, provides this cooling junction. After analyzing the various heat sink models, with different geometrical Heat sink fins, cylindrical-shaped fins's-height at 10 mm temperature cooled to 6.7℃ and pressure loss to 1.8Pa from high temperature were found to be most effective for thermoelectric generator efficiency. The improvement in temperature and pressure loss was achieved using the optimized cylindrical heat sink with 10mm fins height design.

“…Using Thermoelectric Coolers has many benefits: (a) low-maintenance cost as it does not have any moving part; (b) ability to cool/heat below or above ambient temperature; (c) the module can be employed as a heating or cooling source; (d) precise temperature control; (e) high reliability and extensive life-time due to their solid-state construction; and (f) no electrical or acoustical noise. Additionally, they are inexpensive, lightweight, and efficient, making them a suitable choice for the intended application [60].…”

In the rise of recent advancements in unmanned aerial vehicles, many studies have focused on using multi-modal platforms for remote inspection of industrial and construction sites. The acquisition of multiple data modalities assists the inspectors in acquiring comprehensive information about the targeted components. Despite the benefits of multi-modal platforms, the calibration and fusion of the obtained data modalities present many challenges that need to be addressed. Using a calibration board with geometrically known features to estimate intrinsic and extrinsic parameters and accurately align the images in thermal and visible spectral bands, is one of the main approaches to address the problem of dissimilarity of feature appearances in different spectrums.This study presents a comprehensive platform for drone-based multimodal inspection of industrial and construction components, including three main components: 1) a sensor setup that can be used as a standalone system or a payload for a drone; 2) a multi-modal embedded system; and 3) a novel calibration board for multi-modal data fusion. The multi-modal embedded system provides the required features to record, transmit, and visualize the thermal, visible, and depth data synchronously. Additionally, the system presents a multi-modal fusion technique to form RGBD&T data containing thermal and texture information of the obtained 3D view. Moreover, this study introduces a novel self-heating calibration board that uses Thermoelectric Peltier modules to provide an identifiable and sharp pattern in thermal and visible images. The calibration board is designed with an aim also to be used as Ground Control Point (GCP) in drone surveys.INDEX TERMS Multi-modal sensory platform, unmanned aerial vehicle, calibration board, data fusion, ground control point, thermography.
