The results of physical modeling of the functional characteristics of sensors of fields and environment based on islet nanostructures, depending on their size, are presented. The advantages of using cobalt and nickel for sensors of weak magnetic fields and aluminum with a surface layer of aluminum oxide for a gas sensor are shown. The results of the dependences of the physical parameters of the magnetic field and tunneling conductivity in the islet layers of cobalt and aluminum, respectively, on the distances between the islet nanostructures are presented.
