Abstract Ocean wave energy is a reliable and sustainable renewable resource, offering continuous predictable power with minimal land use. Triboelectric nanogenerators (TENGs) technology feasible to convert mechanical in waves into electrical energy, but the harvesting efficient for such wide-ranging, consistent low-frequency tricky challenge. In this study, we introduce multi-stable inverted pendulum TENG (MIP-TENG) two functions including levels predicting. The design of structure, along control system stiffness nonlinearity, discussed detail. Appropriate key structural parameters are figured out achieving vibration amplification within an adjustable band. study also explores intra-well inter-well dynamic behaviors proposes novel method classifying frequency domain. An experimental prototype has been fabricated tested under excitation up 2.2 Hz 8°. Experimental results demonstrate high output performance MIP-TENG confirm feasibility level prediction method. can generate average 0.28 mW 1.8 7.5° sinusoidal base when external circuit resistance 30 MΩ. This provides theoretical support self-powered realization above-mentioned function. Additionally, array developed enable multi-directional harvesting, coupled wind direction detection capabilities.
