Energy harvesting, also known as power harvesting or energy scavenging, involves capturing ambient energy from the environment and converting it into electrical power. This process utilizes various sources such as solar radiation, thermal gradients, wind energy, and kinetic energy. The primary goal is to provide a sustainable and efficient power solution for small, wireless autonomous devices, including wearable electronics, condition monitoring systems, and wireless sensor networks. By harnessing these ambient energy sources, energy harvesting reduces reliance on traditional batteries, addressing environmental concerns and enhancing device performance. en.wikipedia.org
Recent advancements in energy harvesting technologies have significantly improved their efficiency and applicability. For instance, researchers at Seoul National University of Science and Technology (SeoulTech) have developed an innovative design for electromagnetic induction-type vibration energy harvesters (VEHs). This breakthrough aims to enhance the power output of these devices, making them more suitable for a broader range of applications. Additionally, the integration of artificial intelligence (AI) and machine learning into energy harvesting systems has optimized power management, enabling real-time adjustments to harvesting strategies and maximizing efficiency from various energy sources. These developments are paving the way for more sustainable and self-sufficient electronic devices, reducing the need for battery replacements and minimizing electronic waste. scienmag.com
