Physicists and especially applied physicists long for a convenient way for converting mechanical, solar energy, and thermal energy into electricity, which makes up our modern lives—from a small LED light to many integrated communication devices. Since the breakthrough work by Faraday in the beginning of the 19th century, the harvesting of electricity has been the hot topic in our modern society.
