Experimental analysis demonstrates a multi-rectifier triboelectric nanogenerator achieving low crest factor and durable output, suggesting scalable distributed power generation.

Key Points

To develop a parallel triboelectric nanogenerator architecture that eliminates power loss during parallel connection, minimizes output crest factor, and extends operational lifespan.
Engineered a multiple rectifier multiple triboelectric nanogenerator in parallel (MRM-TENG) system.
Integrated a rotational contact–separation structure that introduces a phase difference across rectified units to smooth electrical output.
Tested electrical retention and durability over 7,200,000 rotation cycles at 2.00 r s−1 across a 1,000-hour operational period.
Decreased the current crest factor to 1.31 in the MRM-TENG design, compared to values exceeding 6 in conventional parallel configurations.
Retained approximately 93% of initial electrical output after 7,200,000 rotations over 1,000 hours of continuous operation.
Achieved linear growth of equivalent current with stable low crest factors in parallel mode without electricity loss.
