Research on Wearable Nano Generator got featured on University Portal and National News Portals

Our latest research on wearable generator on University portals and different national news portals. Surface modification of triboelectric negative layers is an essential factor for boosting the output performance of triboelectric nanogenerators (TENGs). Herein, a novel scalable surface modification method is introduced using a fabric-assisted micropatterning technique on a highly negative MXene/silicone nanocomposite surface (charge generating) with MXene layer (charge trapping) for self-powered sensors and wearable electronics. The microstructured surface is fabricated directly from a fabric template requiring no surface-active agent, high-pressure equipment, or high vacuum. To boost the proposed double-side-contact TENG (DSC-TENG) output performance, different parameters of the fabric textures are tested and optimized for the roughened microstructures, namely the MXene layer and relative humidity. Under optimal conditions, the fabricated DSC-TENG improves the voltage and peak current density by factors of 9.8 and 20, respectively, regarding flat silicone. It exhibits a maximum peak power density of 55.47  W m−2 at load resistance of 0.18 MΩ, and a corresponding decrease in resistance by 75% using MXene content of 3mg cm−2. Also, DSC-TENG-based smart home control of electrical appliances, theft protection, self-powered electronic devices, password authentication, and human motion monitoring via smartphone for the IoT are demonstrated. The proposed method can be implemented for different types of polymers, thereby enabling the large-scale fabrication of high-performance TENGs in industrial applications.
