Abstract
In this work, an oscillating float-type piezoelectric-triboelectric-electromagnetic hybrid wave energy harvester (PTE-HEH) used in fish-attracting lamp is proposed. It integrates three power generation methods and makes reasonable use of space, and the three power generation methods can complement each other. The theoretical analysis, simulation analysis, and experimental test of PTE-HEH are carried out. The variation trend and optimal parameters of each unit are found in the theoretical analysis and simulation. In the experiment, when the cantilever beam clamping length is 10 mm, the triboelectric mode of fluorinated ethylene propylene (FEP) film and copper foil independent triboelectric layer is adopted, and the number of magnets is 3, the output performance of PTE-HEH reaches the optimal state. When the external load resistance is 0.4 MΩ, the maximum output voltage is 69.52 V, and the maximum output power can reach 15.80 mW. It is greater than the sum of the output power of the three generators when they work alone. The power density can reach 25.99 W m−3. PTE-HEH can light 97 LEDs and power the temperature and humidity sensor. The PTE-HEH also makes the normal operation of fish-attracting lamp. The combination of PTE-HEH and fish-attracting lamp provides a new scheme for the subsequent development of self-powered fishing devices at sea.
期刊介绍：
Smart Materials and Structures (SMS) is a multi-disciplinary engineering journal that explores the creation and utilization of novel forms of transduction. It is a leading journal in the area of smart materials and structures, publishing the most important results from different regions of the world, largely from Asia, Europe and North America. The results may be as disparate as the development of new materials and active composite systems, derived using theoretical predictions to complex structural systems, which generate new capabilities by incorporating enabling new smart material transducers. The theoretical predictions are usually accompanied with experimental verification, characterizing the performance of new structures and devices. These systems are examined from the nanoscale to the macroscopic. SMS has a Board of Associate Editors who are specialists in a multitude of areas, ensuring that reviews are fast, fair and performed by experts in all sub-disciplines of smart materials, systems and structures.
A smart material is defined as any material that is capable of being controlled such that its response and properties change under a stimulus. A smart structure or system is capable of reacting to stimuli or the environment in a prescribed manner. SMS is committed to understanding, expanding and dissemination of knowledge in this subject matter.
