Special Issue Information

Dear Colleagues,

Through the use of Maxwell’s displacement current as the driving force to effectively convert mechanical/thermal energy into electric power, nanogenerators (NGs) are now flourishing. In addition to targeting self-powered sensor needs at a large scope, nanoenergy sensors have also been developed, aiming to use nanotechnology to harvest the energy required for sustainable, independent, and maintenance-free operation of micro-/nanosystems and mobile/portable electronics. Based on three effects—piezoelectricity, triboelectricity, and pyroelectricity—NGs have broad applications in energy science, environmental protection, wearable electronics, self-powered sensors, medical science, robotics, and artificial intelligence.

This Special Issue of Nanomaterials aims to cover the most recent advances in energy harvesting and sensing for the preparation of different kinds of NGs, and related physicochemical effects, such as tribotronics, piezotronics, piezophototronics, pyroelectric, and flexotronics, as well as potential applications such as wearable electronics, self-powered sensors, and blue energy.

We welcome full papers, communications, and review articles emphasizing the broad scope of the Special Issue.

The combination of nanogenerator technology and traditional textile materials has given rise to textile-based triboelectric nanogenerators (T-TENGs) structured from fibers, yarns, and fabrics. Due to their lightweight, flexibility, washability, and cost-effectiveness, T-TENGs offer a promising platform for powering and sensing in next-generation wearable electronics, with particularly significant potential in smart healthcare and sports monitoring. However, the inherent electrical and structural limitations of textile materials often restrict their power output, signal stability, and sensing range, making it challenging to achieve both high electrical performance and high sensing sensitivity. This review focuses on the application of T-TENGs in smart healthcare and sports. It systematically presents recent developments in textile material selection, sensing structure, fabric design, working mechanisms, accuracy optimization, and practical application scenarios. Furthermore, it provides a critical analysis of the recurring structural and material limitations that constrain performance and offers constructive pathways to address them. Key challenges such as the low charge density of textile interfaces may be mitigated by selecting low-hygroscopicity materials, applying hydrophobic treatments, and optimizing textile structures to enhance contact efficiency and environmental stability. Issues of signal instability under dynamic deformation call for advanced structural designs that accommodate strain without compromising electrical pathways, coupled with robust signal processing algorithms. By providing a comparative analysis across materials and structures, this review aims to inform future designs and accelerate the translation of high-performance T-TENGs from laboratory research to real-world implementation.
