Abstract Benefiting from the widespread potential applications in era of Internet Thing and metaverse, triboelectric piezoelectric nanogenerators (TENG & PENG) have attracted considerably increasing attention. Their outstanding characteristics, such as self-powered ability, high output performance, integration compatibility, cost-effectiveness, simple configurations, versatile operation modes, could effectively expand lifetime vastly distributed wearable, implantable, environmental devices, eventually achieving self-sustainable, maintenance-free, reliable systems. However, current triboelectric/piezoelectric based active (i.e. self-powered) sensors still encounter serious bottlenecks continuous monitoring multimodal due to their intrinsic limitations monomodal kinetic response discontinuous transient output. This work systematically summarizes evaluates recent research endeavors address above challenges, with detailed discussions on challenge origins, designing strategies, device corresponding diverse applications. Finally, conclusions outlook regarding gap systems are provided, proposing necessity future development this field.

Wearable devices for human motion monitoring have garnered significant attention in recent years. In this work, the polyvinyl chloride (PVC)/MXene electrospun film-based triboelectric nanogenerator (PM-TENG) was developed efficient mechanical energy harvesting. Using PVC/MXene as negative material and aluminum foil positive material, PM-TENG exhibits significantly enhanced performance, achieving a 325% increase open-circuit voltage, 490% short-circuit current, 225% transferred charge compared to pure PVC. These enhancements are attributed MXene’s high conductivity, large surface area, excellent trapping capabilities. The delivers maximum power output of 4.94 mW at an optimal load resistance 10 MΩ boasts density mW/cm2, outperforming existing devices. It also demonstrates environmental durability, stability, multifunctional sensing capabilities, including physiological signals biomechanical movements, making it promising candidate self-powered wearable sensors, harvesting, gesture recognition, healthcare applications. This research highlights potential high-performance, systems harvesting sensing, paving way advancements electronics, health monitoring, sustainable solutions.
