Can energy-harvesting devices generate high densities of induced voltage?
In summary, based on the defective state characteristics of metamaterials, energy-harvesting devices can also generate high densities of induced voltage under the excitation of small waves, efficiently converting small wave energy into electrical energy for low-power devices.
Can a self-powered ocean health monitoring system convert wave energy into electrical energy?
An experimental rig of a self-powered ocean health monitoring system that converts wave energy into electrical energy for the normal operation of the monitoring system is illustrated in Fig. 4 a. 16 empty balls are placed around the high-density energy-harvesting metamaterial plate to maintain sufficient buoyancy during practical tests.
How a stable power supply can be used for ocean monitoring?
For the first time, a stable power supply for the monitoring system has been realized in various weather conditions (24 h). Up to 70% of the Earth’s surface area is covered by oceans, and the construction of the Ocean Internet of Things (OIoT) by various countries aims to monitor various ocean parameters.
What are the advantages of ocean wave energy harvesting?
For monitoring devices and sensing networks operating in the ocean, ocean wave energy harvesting offers several advantages, including (1) the highest energy density among all renewable energy sources 23, (2) no chemical pollution to the ocean environment, and (3) a longer average time of availability.
What is the RMS value of simulated ocean wave frequency?
At a simulated ocean wave frequency of f = 4 Hz, which is outside the frequency range of the metamaterial local resonance band gap, the RMS value of the output voltage is 0.01 V, and the band gap frequency is within the metamaterial energy. The output voltage capability of the harvesting device increased by %.
