Získávání elektrické energie z půdy a vzduchu pomocí termoelektrického generátoru

Abstract

This thesis aims to build a working prototype of a device for energy harvesting from the soil and ambient air using a thermoelectric converter. The theoretical part of this thesis describes the different physical principles used by thermoelectric converters. The various principles and technologies of suitable temperature sensors for measuring the temperature in the soil profile are also described. A survey of ambient energy harvesting devices using similar principles to harvest energy from the temperature difference between the soil and the surrounding environment is included at the beginning of the practical part of this thesis. The practical part also includes the actual design and construction of a working prototype of the device and its subsequent implementation. A measurement chain is developed for this prototype to perform the collection of measured parameters on the prototype in application conditions. The results are then statistically processed, discussed, and compared against existing applications.
