The document discusses nanotechnology and its applications in electrical systems. It begins with an introduction to nanotechnology, defining it as engineering at the atomic scale between 1-100 nanometers. It then discusses how properties can differ at the nanoscale. Examples of applications in electrical systems given include using carbon nanotubes for their high conductivity and low resistivity in computer processing. Advantages include increasing memory density and display quality while reducing size, weight and power consumption, though development costs are high. The future scope may include flexible electronics, molecular devices and advances in wireless technologies through nanotechnology.
