Electrospun PVDF-TrFE/MXene Nanofiber Mat-Based Triboelectric Nanogenerator For Smart Home Appliances

This paper reports an electrospun nanofiber-based TENG (EN-TENG) using a PVDF-TrFE/MXene nanocomposite with a superior dielectric constant and high surface charge density. The influence of dielectric properties on the output performance of the EN-TENG is investigated theoretically and experimentally, with applications demonstrated in smart home appliances.

• Development of an electrospun nanofiber-based TENG (EN-TENG) with a PVDF-TrFE/MXene nanocomposite.
• Fourfold improvement in output performance due to the nanocomposite.
• Demonstrated ability to power an electronic stopwatch and thermo-hygrometer from finger tapping.
• Application as a self-powered switch for smart home appliances.

An EN-TENG was fabricated using a PVDF-TrFE/MXene nanocomposite. The effect of the material's dielectric properties on performance was studied. The device's ability to power small electronics and act as a self-powered switch was tested.

The EN-TENG exhibited a maximum power density of 4.02 W/m² at a matching load resistance of 4 MΩ. The nanocomposite improved performance fourfold. The device successfully powered small electronics and was used as a self-powered switch for fire alarms, fans, and smart doors.
