Special Issue Information

Dear Colleagues,

With the rapid advancement of the Internet of Things (IoT) and the era of ubiquitous connectivity, there is an increasing demand for sustainable, lightweight, and pervasive power sources. Traditional rigid batteries, limited by their lifespan and form factor, often hinder the development of conformable and autonomous electronic systems. In this context, Flexible Triboelectric Nanogenerators (TENGs) have emerged as a revolutionary technology capable of converting ambient mechanical energy—such as body motion—into electricity. Due to their unique advantages, including high flexibility, material diversity, and high-power density, flexible TENGs are considered a key technology for next-generation self-powered systems, bridging the gap between energy harvesting and the requirements of flexible electronics.

This Special Issue, titled "Flexible Triboelectric Nanogenerators", seeks to highlight the latest research and technological breakthroughs in this dynamic field. We invite submissions that explore the design, fabrication, and integration of flexible TENGs, with a particular focus on their applications in Human–Machine Interfaces (HMIs), real-time health monitoring, and wearable electronic devices. Topics of interest include, but are not limited to, the development of novel nanomaterials for enhanced output performance, self-powered active sensors for physiological signal detection, smart textiles, and integrated systems for energy harvesting and storage. Both original research articles and comprehensive reviews addressing these advancements and their potential to revolutionize intelligent bioelectronics are welcome.

Abstract
Continuous monitoring of pathological motor features is vital for post-stroke rehabilitation but remains challenged by power reliance and low sensitivity of wearable sensors. Here, we develop a high-sensitivity, self-powered breathable nanogenerator (BN-TENG) utilizing fish-scale-derived biological hydroxyapatite/carbon (Bio-HAp/C) fillers within electrospun polyvinylidene fluoride (PVDF) [...] Read more.
Continuous monitoring of pathological motor features is vital for post-stroke rehabilitation but remains challenged by power reliance and low sensitivity of wearable sensors. Here, we develop a high-sensitivity, self-powered breathable nanogenerator (BN-TENG) utilizing fish-scale-derived biological hydroxyapatite/carbon (Bio-HAp/C) fillers within electrospun polyvinylidene fluoride (PVDF) nanofibers. The Bio-HAp/C enhances electron-trapping capability, while a high-resilience ethylene-vinyl acetate (EVA) spacer optimizes contact-separation dynamics. The BN-TENG achieves a superior sensitivity of 16.28 V·N−1 and remarkable stability over 10,000 cycles. By implementing a multi-node sensing strategy, the sensor successfully captures complex hemiplegic patterns, including compensatory shoulder hiking, distal muscle spasticity, and postural asymmetry. By resolving subtle micro-vibrations missed by traditional electronics, this work provides a sustainable, autonomous interface for characterizing pathological motor features and assessing rehabilitation progress in hemiplegic patients.
