Improved Path Planning Techniques for Ambient Energy-powered IoT Collection Systems | Chapter 5 | Engineering Research: Perspectives on Recent Advances Vol. 9

Energy harvesting systems, when combined with Internet of Things (IoT) technologies, present a promising path toward self-sustaining and environmentally friendly power solutions. These systems harness ambient energy—such as solar radiation, wind, mechanical vibrations, and thermal gradients—and convert it into electrical energy to power IoT devices. This paper explores recent innovations in circuit design that support energy harvesting in IoT applications, emphasising improvements in energy capture, power management, and storage. Particular attention is given to Maximum Power Point Tracking (MPPT) algorithms, which optimise the energy extraction process from diverse and variable sources. The development of ultra-low-power circuit architectures is discussed as a means to enhance the performance of energy harvesting systems under minimal energy availability. The roles of supercapacitors and rechargeable batteries are examined as energy storage solutions, with a focus on their capabilities for buffering and maintaining consistent power delivery. Advanced battery management techniques—including dynamic charging methods and real-time capacity estimation—are also analysed. Voltage regulation, a key aspect of stable power supply in IoT systems, is addressed through recent advancements in low-dropout regulators (LDOs) and high-efficiency voltage converters. The integration of these energy harvesting systems with IoT platforms is explored, highlighting the design challenges and benefits in building energy-aware IoT applications. Finally, the importance of energy-efficient communication protocols and adaptive data processing algorithms is emphasised as essential components for minimising energy consumption in IoT networks.
