. Imagine graphene wallpaper that absorbs the majority of light in your home and produces enough electricity to meet all of your electricity needs. Scientists have created this amazing technology that could make it a reality. The graphene wallpaper was developed by researchers at the University of Surrey’s Advanced Technology Institute, England. It can generate electricity in dark rooms. Animals like moths can still see well in dark rooms, even though it may seem dim for human eyes. Scientists were inspired by the moths’ ability to see in darkness to create graphene. Your home could be powered by heat and light generated from graphene wallpaper. Image: University of Surrey. Could this technology be the Holy Grail in combating climate change? It could drastically reduce the electricity that we produce from burning fossil fuels. Could this be the start of the end for domestic electricity bills? The remarkable properties of graphene continue to be highlighted. It is not only the strongest and thinnest material known, but it also conducts electricity and heat very well. It is light-weight and absorbs the least amount of energy. The Internet of Things: Powering it Professor Ravi Silva (Head of the Advanced Technology Institute) and his colleagues stated in Science Advances that the nanometer thin material is capable of powering a variety of applications using the growing number of Internet of Things. Internet of Things is a term that refers to an idea for the Internet where virtually every object would have access to the Internet and could send and receive information. Graphene, a single-atom thick layer of carbon pure, is called graphene. These carbon atoms have been bonded in a hexagonal honeycomb structure. This invention has been called one of the most important in recent history. Image: fkf.mpg.de. The Internet of Things Agenda describes the Internet of Things in the following way: “The Internet of Things is a collection of unique, interconnected computing devices and machines that provide unique identifiers. It allows for data to be transferred over a network, without the need for human-to human or computer interaction.” Graphene – remarkable material Graphene is a new, remarkable material. It is composed of a single layer of carbon atoms, which is arranged in agonal, six-sided, hexagonal, It is more than 207 times stronger than steel, and it’s thinner and lighter than any other material. Professor Silva explained that he was inspired by nature and created ultra-thin graphene sheets specifically for capturing significantly more light. Nanotexturing is a method that involves adding graphene to a metallic surface. The material then becomes covered with nano-sized and one-dimensional structures. The term nanotechnology refers to working at the molecular and atomic level of things, such as. super-super tiny. Graphene, despite its strength, has historically not been very effective at absorbing light. The scientists developed nano-patterning, which allows light to be focused into tiny gaps between the surface and the texture. This made graphene absorb 90% less light. The eyes of moths have been designed to allow them to see in the darkness. The eyes channel light toward the center of their eye. To make graphene super-light-absorbing, the Surrey researchers used this same method. (Image: rolith.dreamhosters.com) Inspiration from the eyes of moths Regarding how nature adapts to its environment, Prof. Silva said: “Nature has evolved simple yet powerful adaptations, from which we have taken inspiration in order to answer challenges of future technologies. The microscopic patterns in moth eyes allow them to see even under the darkest of conditions. Many researchers consider graphene to be the next breakthrough in technology. We used this same method to create an amazingly thin and efficient light-absorbent materials by patterning graphene the same way. It is known for its remarkable mechanical strength and electrical conductive abilities. It can be used in many electronic applications. For example, it could make a spider web to catch full-sized aircrafts. Graphene electronic devices can be printed onto the skin of humans, creating an in-body communication system. (Image: www.manchester.ac.uk) It also improves energy storage, which could mean that the bulky batteries currently used in electric cars might become smaller and lighter. Graphene must harvest heat and light. Professor Silva and his colleagues stated that graphene should also be able to harness heat and light effectively in order to become a popular product. Professor Silva stated that graphene can generate power from very low light. This coating could be used indoors as part of future smart wallpapers or windows. It could produce electricity from heat or waste light, which could power a variety of smart applications. The team believes this type of graphene coating could also help new types of energy harvesters, and other sensors that are connected to the Internet of Things. Italian researchers discovered that graphene can be used to spray spiders with super-bionic material. This makes it strong enough for them to capture a fallen airplane. Jose Anguita from the Advanced Technology Institute’s Nanoelectronics Centre was the lead author. He stated that graphene can only absorb a tiny percentage of light falling on it because of its thinness. It is therefore not suitable to be used in optoelectronic technology of the future. “Nanotexturing graphene channels light through the nanostructures and increases the amount that the material absorbs.” Even nanometre thin films can now show strong light absorption. “In general, a graphene sheet will absorb between 2 and 3 percent light. Our nanotextured, few-layer, thin graphene sheet absorbs 95% light from a wide spectrum of wavelengths, including the UV and infrared. Professor Silva spoke out about graphene’s possible applications. He said that the scientists were excited by the possibility of using the material in optical devices to enhance performance and also to explore new uses. “Through Surrey’s EPSRC funded Graphene Centre we are seeking industry partners to exploit the technology. We are interested in hearing from companies who can share our vision with us. Citation: “Ultrabroadband light trapping with nanotextured graphene multilayers,” S. Ravi P. Silva and Jose V. Anguita.
