Nanotechnology is a branch of technology that deals with matter at a molecular scale. By manipulating the arrangement of atoms, it’s possible to change the nature of the material they compose. According to the latest Nanotech News, nanotechnology is being used to improve the performance of drones and UAVs, particularly in the field of agriculture.
Drones In Agriculture
Agricultural drones provide farmers with a bird’s-eye view of their crops, giving them valuable information they could not otherwise access. With infrared images, farmers can detect signs of disease in plants that they would not be able to see with their eyes alone. In addition, drones can do certain types of agricultural work, like spraying crops with fertilizers or pesticides. Advances in drone technology are thus helping farmers increase productivity and reduce their costs. Nanotechnology is making a difference in the following ways.
Under the best circumstances, agricultural drones don’t have a very long flight time. Most last only ten to fifteen minutes in the air. When a drone is carrying a liquid crop spray, the weight of the spray can shorten that time even further. However, the lighter the weight of the liquid it carries, the longer and farther a drone will be able to fly. With nanotechnology, scientists are developing more potent liquids, meaning that drones carry less of it and spray it in a finer mist.
Another factor in a drone’s flight time is its battery life. Standard batteries cannot keep a drone in the air very long, and having to recall drones frequently to change batteries is not the most efficient use of time. However, through nanotechnology, new graphene batteries are being developed that can increase performance by 50%. Even an extra 5 minutes on each flight can make a big difference over the course of a day’s work.
Stronger Drone Components
Drones have to be sturdy to withstand inevitable crashes and collisions. A new nanocoating can help protect drones not only from impact but also from weather by shielding it from moisture and insulating it against extremely hot or cold temperatures. Because the coating is no thicker than a molecule, it adds nothing to the weight of the drone.
