A nano-antenna is a type of solar cell that makes use of infrared radiation to create electricity instead of harnessing visible light to create electricity where infrared radiation is often believed as heat and exists beyond the visible range for humans. Infrared light is emitted from the Earth and also from various industrial processes like waste energy and coal-fired power plants. One version of the nano-antenna takes the shape of a microscopically small gold square or spiral of metal wire about 1/25th the diameter of a human hair that is embedded in a flexible polyethylene plastic sheet. In researches, the devices have been shown to be as high as 92% efficient at converting the frequencies of infrared light which they capture and convert into electrical energy. Finally, we conclude the current status of this ﬁeld and the major establishments and emerging lines of analysis in this area of research. The sharing and coordination of information among these nano-devices leads towards the development of nano-networks in the future, increasing the range of applications of nanotechnology in the environmental, biomedical and military ﬁelds.
