The emerging focus on smart cities and smart homes includes a redoubled focus on innovative power solutions.
Energy fields such as heat, light and sound are all around us. Through a method known as energy harvesting, we can now collect and harness some of this energy to power everyday devices. The technology is still developing, but it holds great potential for the future.
Energy harvesting is defined as the process by which ambient energy is collected and utilized for on-demand, off-grid use. It takes energy that is all around us – including mechanical, chemical and thermal – and supplies energy when it is needed and when other methods such as grid electricity are not available.
