Abstract Triboelectric nanogenerator (TENG) offers a novel approach for converting high‐entropy mechanical energy into electrical energy, yet achieving high charge density remains critical. Optimizations using dielectrics with specific capacitance have mitigated air breakdown, but loss within persists as limiting factor.

With modified interfacial traps, an ultrahigh of 9.23 mC m −2 is achieved in external excitation (ECE) TENG 0.2 vol% PEI/P(VDF‐TrFE‐CFE) film, marking the highest reported single‐unit TENGs. This work provides material strategies high‐performance TENGs, paving way their large‐scale practical applications.

Charge excitation is a key method to enhance the output of floating rotary triboelectric nanogenerator (FR-TENG). However, most current research focuses on improving surface charge density single material, neglecting strategy simultaneously increasing two materials with opposite polarities potential difference. Here, we propose coinjecting positive and negative charges using voltage-multiplying circuit (VMC), applied self-excited TENG (FSR-TENG). The VMC injects into adjacent, nonconductive electrode groups stator. This increases difference between groups, thereby effectively enhancing device's output. Compared FR-TENG, transferred increase by 341% 421%, respectively. work provides an innovative for maximizing rotational TENGs can be easily other types TENGs.
