Abstract — Solar Energy Harvesting For Low Power IoT Nodes
(PV) and thermal hybrid energy-harvesting system that can be utilized to power IoT sensor nodes with active RFID tags. The indoor light energy was harvested using 5-sided PV cells, which could generate 3 times more energy than most current studies using single-sided PV cells. In addition, two vertically stacked thermoelectrical generators (TEG) with a heat sink were utilized to harvest thermal energy. Compared to one TEG, the harvested power was improved by more than 219.48%. In addition, an energy management module with a semi-active configuration was designed to manage the energy stored by the Li-ion battery and supercapacitor (SC). Finally, the system was integrated into a 44 mm × 44 mm × 40 mm cube. The experimental results showed that the system was able to generate a power output of 192.48 µW using indoor ambient light and the heat from a computer adapter. Furthermore, the system was capable of providing stable and continuous power for an IoT sensor node used for monitoring indoor temperature over a prolonged period.
Operational Methodology & Framework
Figure 2: Conceptual Model & Experimental Workflow for Solar Energy Harvesting For Low Power Iot Nodes 3. Algorithmic Processing & Methodology Keywords: hybrid energy harvesting, Internet of Things (IoT), self-powered, solar energy, thermoelectric With the rapid development of sensor and microelectromechanical technologies, the performance of IoT sensor devices has increased and their size has shrunk . As a result, these devices have garnered tremendous attention from both industry and the public in the past decade, owing to their versatility and applicability in numerous domains such as smart logistics, smart factories, smart agriculture, and smart home-building .
Experimental Findings & Validation
However, IoT sensors powered by batteries have a limited lifespan and maintaining them can be costly. Moreover, discarded batteries containing various heavy metals pose a significant environmental burden . In this context, harvesting energy from the environment has emerged as a promising alternative to batteries, attracting interest from researchers across various fields. By harnessing energy from sources such as light, heat, and mechanical energy, the IoT system’s sensors can enjoy significantly extended lifespans [ 4 , 5 , 6 , 7 , 8 ].
