Abstract The summary has been shortened to the following: integration of triboelectric nanogenerators (TENGs) and electromagnetic generators (EMGs) is an effective strategy for constructing high‐performance blue energy harvesters. However, in conventional hybrid nanogenerators, TENGs EMGs function independently, lacking a cooperative effect. This, combined with suboptimal spatial efficiency, restricts their overall output performance. In this study, compact, multi‐mode generator (MMHG) proposed composed free standing TENGs, contact‐separation EMGs. These leverage synergistic interaction between gravitational, magnetic, inertial forces. On six‐degree‐of‐freedom platform, free‐standing TENG achieve maximum transferred charges 83 187 nC respectively, while EMG reachs peak open‐circuit voltage short‐circuit current 4.59 V 1.94 mA, achieving power density 125.41 W m −3 . Triggered by water waves lab, 5‐integrated MMHGs charge 10 mF capacitor 3.59 within 158 s. real ocean, 81.17 184.7 reaching 2.87 1.42 mA. MMHG efficiently harvests ocean wave energy, serving as good reference development self‐powered marine devices.
