استهسال انرژی ایجاد شده بر اثر ارتعاش ناشی از گردابه ها (vortex induced vibrations for aquatic clean energy) یا بطور مختصر vivace روشی نوین برای تولید انرژی پاک از جریان سیالات است.در این روش عبور جریان از اطراف یک استوانه باعث ایجاد ارتعاش شده و نیروی مورد نیاز برای حرکت دادن یک مولد الکتریکی را فراهم می آورد.
Energy harvesting is a technology that gathers energy such as sunlight, artificial light, and vibration and heat from machinery to obtain electric power. Applying this technology to wireless sensor modules in a machine-to-machine (M2M) wireless sensor network will eliminate the need for grid-based power and primary batteries and create new value in the form of maintenance-free, battery-free, an...
Clean energy harvesting and usage has gained considerable attention in the last few decades. While the horizontal axis wind turbines have been used extensively, they have certain defects and functional limitations. In the present paper, a novel oscillatory wind turbine is proposed. The conceptual design of the new turbine together with its configuration is explained. Dynamical equations of the ...
The continuous use of fuels like petroleum is recognized as unsustainable because of their natural exhaustion and contribution to the pollution in the environment. Not only for the environmental perspective but also for the economic sustainability, we necessarily need to develop alternative, renewable and pollution free fuels. Harvesting energy from the sun (solar energy), earth (geothermal ene...
The collection of clean power from ambient vibrations is considered a promising method for energy harvesting. For the case of wheel rotation, the present study investigates the effectiveness of a piezoelectric energy harvester, with the application of stochastic resonance to optimize the efficiency of energy harvesting. It is hypothesized that when the wheel rotates at variable speeds, the ener...
Currently, wearable electronics are increasingly widely used, leading to an increasing need of portable power supply. As a clean and renewable power source, piezoelectric energy harvester can transfer mechanical energy into electric energy directly, and the energy harvester based on polyvinylidene difluoride (PVDF) operating in 31-mode is appropriate to harvest energy from human motion. This pa...
Energy use is central to human society and provides many health benefits. But each source of energy entails some health risks. This article reviews the health impacts of each major source of energy, focusing on those with major implications for the burden of disease globally. The biggest health impacts accrue to the harvesting and burning of solid fuels, coal and biomass, mainly in the form of ...
energy harvesting from surrounding environment has been attractive for many researchers in recent years. therefore, developing appropriate test apparatus to study energy harvesting mechanisms and their performance is of paramount importance. due to their electromechanical characteristics, piezoelectric materials are used for harvesting energy from environmental vibrations. for optimum utilizati...
This Tutorial teaches the essential development of nitrogen-plasma-assisted molecular-beam-epitaxy grown InGaN nanowires as an application-inspired platform for energy harvesting and conversion applications by growing dislocation- strain-relieved axial InGaN-based nanowires. The aims to shed light on interfacial, surface, electrical, photoelectrochemical characteristics through nanoscale ultraf...
