Fabric-Assisted MXene/Silicone Nanocomposite-Based Triboelectric Nanogenerators for Self-Powered Sensors and Wearable Electronics

This paper introduces a novel, scalable surface modification method using a fabric-assisted micropatterning technique on a highly negative MXene/silicone nanocomposite surface. This method boosts the output performance of TENGs for self-powered sensors and wearable electronics. The technique is simple, requiring no special equipment.

• A novel, scalable fabric-assisted micropatterning technique for TENGs.
• Significant improvement in voltage (9.8x) and peak current density (20x) compared to flat silicone.
• Demonstration of various smart home and IoT applications, including theft protection and password authentication.
• A versatile method applicable to different polymers for large-scale industrial fabrication.

A double-side-contact TENG (DSC-TENG) was fabricated using a fabric template to create microstructures on a MXene/silicone nanocomposite. The performance was optimized by testing different fabric textures, MXene content, and relative humidity. The device was then used to demonstrate various smart home and IoT applications.

The DSC-TENG exhibited a maximum peak power density of 55.47 W m⁻² at a load resistance of 0.18 MΩ. The device successfully demonstrated applications in smart home control, theft protection, password authentication, and human motion monitoring for the IoT, proving the method's potential for industrial-scale fabrication.
