US 2026/0168475 A1 · HARVESTING ENERGY FROM BODIES EXPERIENCING WAVE MOTION

Abstract

Systems, methods, and other embodiments described herein relate to harvesting circular motion, such as from waves in the ocean. In one embodiment, an energy harvesting device includes a cantilevered shaft attachable horizontally to a body experiencing wave motion. A resonator mass is attached to a free end of the cantilevered shaft. The resonator mass moves with circular motion as the body experiences the wave motion. The energy harvesting device also includes an energy conversion system operatively coupled to the cantilevered shaft. The energy conversion system generates electrical energy from two orthogonal motion components of the circular motion of the resonator mass. The energy harvesting device also includes an energy storage device to store the electrical energy.
