This invention discloses a variable cross-sectional area friction-electromagnetic composite power generation raft buoy and method, solving the problems of low power generation efficiency caused by the non-adjustable natural frequency and mismatch between the optimal operating frequencies of TENG and EMG in existing wave energy buoys. This invention dynamically adjusts the raft width through a symmetrically arranged variable cross-sectional area mechanism, enabling the natural pitch frequency to track common ocean wave frequencies of 0.5Hz-2Hz in real time, achieving broadband resonance energy capture. It innovatively designs a dual-path transmission module, simultaneously decomposing the same wave pitch motion into a low-frequency extension motion matching the TENG and a high-frequency linear motion matching the EMG, allowing both to operate within their peak efficiency range. Hydraulic transmission is used to transfer mechanical energy, and multiple buoys can be quickly hinged together to form an expandable power generation array. This invention improves wave energy capture efficiency by more than 3 times across all sea states and increases total power generation by more than 60%, making it suitable for self-powering distributed equipment such as ocean buoys, observation stations, and underwater sensors.
