Energy harvesting technologies are growing rapidly in recent years because of limitation by
energy storage and wired power supply. Vibration energy is abundant in the atmosphere …

There is a high demand for novel flexible micro-devices for energy harvesting from low-
frequency and random mechanical sources. The research of new functional designs is …

Vegetation has important functions of conserving water sources, reducing surface sediment
transport, slowing down the process of soil erosion, purifying soil quality and filtering …

Energy harvesting technology plays an important role in converting ambient energy into
useful electrical energy to power wireless sensing and system monitoring, especially for …

In order to solve the problem of self-energy supply of vehicle-mounted micro-sensors, bridge
detection and some other low-power electronic devices in their working state, a vortex …

The effect of vegetation density on overland flow dynamics has been extensively studied, yet
fewer investigations have focused on vegetation arrangements with different densities and …

The trailing-edge vortex-shedding flow is a typical flow model, which is greatly useful in
researching the formation, propagation, and decay of the Karman vortex. However …

Vegetation lodging downstream under overland flow is a common phenomenon; it changes
the characteristics of the overland flow regime and causes the resistance effect. At present …

A Karman vortex is a phenomenon of fluid flow that can cause fluctuation and vibration. As a
result, it leads to fatigue damage to structures and induces safety accidents. Therefore, the …

Purpose This paper aims to design an optimum vertical axis wind turbine (VAWT) and
assess its techno-economic performance for wind energy harvesting at high-speed railway …
