In a review, researchers summarize tribovoltaic nanogenerators for harvesting human motion energy. These systems not only produce stable direct-current electricity with high power density but also enable self-powered sensing for real-time motion and physiological monitoring. Advanced materials, interface engineering, and textile designs further enhance flexibility, durability, and performance for wearable applications.

Fruit volume in Chinese flowering plants is largely shaped by evolutionary relationships, but warmer climates weaken this phylogenetic constraint, highlighting the context‑dependent role of evolutionary history in plant reproductive traits.
