The blistering development of the Internet of Things (IoT), wearable devices, and wireless sensor networks has intensified the need in regard to self-sustaining embedded systems that could perform without the need to replace batteries or use other sources of energy regularly. Conventional power technologies are highly restrictive in the device lifespan, scalability, and sustainability of the environment. Consequently, energy collecting and energy keeping solutions have become significant enablers of a low-power embedded system. This paper describes the state of the art of energy harvesting technologies, such as solar, thermal, vibration, piezoelectric, and radio frequency (RF) energy, and their suitability in implementing energy harvesting technologies in ultra-low-power devices. More so, it discusses how advanced storage systems like thin-film batteries, supercapacitors, and hybrid systems of energy storage can be used in a complementary fashion in keeping the operation steady and continuous. The power management techniques that make use of adaptive algorithms, duty cycling, and the use of energy-conscious design as a way of maximizing energy efficiency are also discussed. Practical examples of IoT, smart cities, sensorimeters, as well as medical tools are presented, and they indicate how revolutionary these technologies are. Lastly, the paper establishes the main obstacles that exist, including scalability, energy conversion efficiency, and cost-effectiveness, and projects future research opportunities in order to realize fully autonomous, sustainable, and intelligent embedded systems.
