Harvesting energy from ocean waves has been a promising renewable energy source due to its high efficiency, carbon-free, not affected by the depletion of fossil fuels, and replenished nature. Numerous studies have been conducted on wave energy to explore an efficient way to harness energy from wave energy. Among them, linear generators and slider crank mechanism based rotational generations have become common topics in research, which have some limitations due to lower efficiency and technologically challenging. Thus, in this work, wave energy harvesting technique using rotational generator based on scotch yoke mechanism is proposed. A typical slider cranks to convert linear motion into rotational motion is replaced by scotch yoke mechanism to yield higher efficiency since scotch yoke is less in terms of weight, length and space. A comparison of the performance of wave energy system between employing slider crank and scotch yoke is made to evaluate the superiority of the proposed mechanism. From the results obtained in this work, it is found that the output power almost 3.8 W of a rotational generator employing scotch yoke mechanism is higher compared to the output power, which is approximately 2 W of rotational generator employing slider crank for the same input power. Thus, rotational generator by employing scotch yoke mechanism can be one of the alternative methods for ocean wave energy harvesting. © 2022 AIUB Office of Research and Publication.
