Hydrovoltaic Electricity Generators
The hydrovoltaic electricity generator (HEG) utilizes the surrounding water and/or moisture to expose the electrodes to dissimilar physicochemical environments, resulting in autonomous voltage and current generation. Therefore, hygroscopic materials such as hydrogels, which effectively absorb water, significantly enhance the electrical performance of HEGs. Through...
The global energy crisis caused by the overconsumption of nonrenewable fuels has prompted researchers to develop alternative strategies for producing electrical energy. In this review, a fascinating strategy that simply utilizes water, an abundant natural substance throughout the globe and even in air as moisture, as a power source is introduced. The concept of the hydrovoltaic electricity generator...
