Energy harvesting is the technology where the sources such as mechanical loading, vibrations, frictions, temperature gradients, magnetic waves, light, biological energy, etc. are converted into device levels of electric power, usually in the µW-mW ranges. These fields are attracting wide attention as "feasible technology" that boosts the IoT and electronic device industry, enriches people’s lives, and minimizes environmental risks and impacts. For energy optimum harvesting, materials development, device design and power management are essential. Even though significant progress has been made on the development of high-performance nanomaterials and device design, there is still much room for further optimization, particularly using machine learning-driven approaches such as deep learning and data mining. Therefore, some imaginary and theoretical modeling studies for developing new energy harvesting materials are also crucial in this symposium. This symposium focuses on the state-of-the-art materials, devices and systems, including piezoelectric, triboelectric, electromagnetic, thermoelectric, piezoelectrochemical, flexoelectric, magnetoelectric, mechanoradical, ionic, pyroelectric, photovoltaic, biological-induced, capacitive, and other all miscellaneous energy harvesting principles for harnessing omnipresent energy sources in our daily life.
