Abstract
The search for sustainable and renewable forms of energy supply has led to the development of new and creative ways to convert available environmental energy into useful electrical energy. In this regard, mechanical energy sources such as vibrations, wind, and ocean waves, are abundant and can be harnessed to power from small electronic devices to small urban centers. Electromagnetic converters, piezoelectric materials, triboelectric structures, and magnetostrictive materials can be cited as viable options for energy harvesting, each with its own set of advantages and disadvantages. Energy harvesting systems that combines multiple transducer mechanisms have emerged as a promising trend in recent literature, as it has the potential to enhance energy harvesting capacity. Additionally, to ensure maximum efficiency in real-world applications, it is important to be able to harvest energy from multiple directions. This feature can be achieved by means of pendulum structures that can diffuse energy between directions within the system. This study investigates the combination of hybrid transducers and multidirectionality by analyzing a prototype of a hybrid electromagnetic-piezoelectric multidirectional energy harvester. Numerical analysis of the prototype are performed offering valuable insights about this type of electromechanical system. Results reveal that the addition of pendulum structures associated with hybrid transduction schemes can enhance energy harvesting performance significantly.
