Background

The ocean covers more than 70% of the earth's surface, and water resources are extremely abundant. Ocean energy is an important renewable clean energy source, and if it can be applied commercially on a large scale, it will make major changes to the global energy structure, political balance, economy and social development. At present, sea water energy mainly comprises tidal energy, wave energy, ocean current energy, temperature difference energy and salt difference energy, and the wave energy is used as an important direction for ocean energy development and is rarely utilized due to the lack of economic energy conversion technology. At present, the electromagnetic power generation technology is mainly adopted to collect water body fluctuation energy, but the conversion efficiency is low for lower water body fluctuation frequency and motion mode. Meanwhile, the electromagnetic power station has higher construction cost and higher requirement on the environment, and is difficult to integrate with a miniaturized water body sensor.

Water body detection plays an important role in national important requirements and scientific frontier research, but the development of the water body detection technology is hindered at present by the sensitivity of a sensor and the power supply problem.
