Abstract
A funnel-shaped underwater energy harvesting equipment includes a piezoelectric element configured to be installed at a seabed and to be moved by a fluid in order to convert vibration energy into electricity. The funnel-shaped underwater energy harvesting equipment further includes a fluid collector coupled to the piezoelectric element and configured to increase velocity of the fluid flowing toward the piezoelectric element. The harvesting equipment exhibits improved energy conversion efficiency, while simplifying the shape of the harvesting equipment.
