![]() ![]() A slider-crank mechanism was used to mimic ocean waves throughout the experiment, and the results showed a close match between the proposed dynamic modeling, FEA simulations, and experimental testing. An experimental prototype was fabricated and tested to validate the results of the dynamic model and the FEA simulation. Next, finite element analysis (FEA) simulations using the commercial software COMSOL-Multiphysics were carried out with the help of a coupled physics analysis of Solid Mechanics and Electrostatics Modules to achieve the output voltages. The developed dynamic model investigated the system’s response to an input of ocean waves and provides design insights into the geometrical and material parameters. To analyze the motion principle and the working performance of the proposed drifter-based piezoelectric sensor, a dynamic model was developed. In the present research, a drifter-based piezoelectric sensor is proposed to measure ocean waves’ height and period. ![]() However, to the best of the authors’ knowledge, although there are various designs of piezoelectric energy harvesters for marine applications, piezoelectric materials have not been employed for sensory and measurement applications in marine environment. What about taking a break ? Make the most the lack of swell to perfect your tan, open a book, spend time with your family or do nothing at all! Sleep late or take a nap, resting also feels really good from time to time.Recently, piezoelectric materials have received remarkable attention in marine applications for energy harvesting from the ocean, which is a harsh environment with powerful and impactful waves and currents. Just for a walk or tough hike, for the day or to spend the night, in the mountains or plains, whatever you prefer. When the sun is a bit shy or when beaches are really crowded going for a hike can be a pretty good alternative to cut yourself off the world for a few hours, revitalize and explore the surrounding nature. It does require a little practice at the beginning but paddle is accessible to everyone, it is the perfect activity to do with family or friends. Besides perfecting your tan, paddle tones up and help with your balance. On the ocean or on a lake, stand up paddle is really nice, especially when the sun is up and the water is steady. It is ideal to put on you fins, mask and snorkel and go explore the ocean floor, swimming in the ocean really gives an amazing feeling of freedom! If there are some small waves you can also have fun bodysurfing or looking at the waves movement from the bottom, it is always surprising to feel the wave underwater. ![]() When there is no swell the ocean is calm and steady, the sand is less moved which makes the water clearer. To avoid going round and round in circles and checking waves every 5 minutes here are a few fun activities to do on the coast when swell decided not to show up. The ocean can be really unpredictable and sometimes it’s not very generous with waves, especially in summer.
