Abstract
In this work, a flexible triboelectric nanogenerator (TENG) integrated with an artificial petal micro/nanostructure surface is proposed and fabricated. The flexible printed circuit is designed to expose the copper electrodes and integrate with the artificial polydimethylsiloxane (PDMS) petal surface as a flexible TENG. The artificial PDMS petal micro/nanostructure surface was fabricated by the rose petal replication process and integrated into the TENG to enhance triboelectric charge transfer. The power generated by the TENG from coupling between the triboelectric effect and electrostatic induction by external mechanical loads can be collected. The generated output open-circuit peak-to-peak voltage can be up to 45.8 V when the externally applied normal pressure is 40 kN m−2. Additionally, a maximum output power of 0.01 μW is achieved with a 1.7 MΩ loading resistance and a critical external applied pressure frequency of 26 Hz.
