Three dimensional conductor wiring

The copper oxide ceramic superconductors are two-dimensional conductors They can conduct a current parallel to the layers of Cu and O atoms but not between the layers. The fullerides, by contrast, are three-dimensional conductors that conduct equally in all directions. Because of this property, they may prove to be superior materials for making superconducting wires. 

The nanocomposile materials of FAU-Agl and MFI-AgI with high guest-contents in the form of quantum wires or three-dimensional nanocrystals exhibit optical properties different from quantum dots. In addition, silver-modified zeolites and silver halide encapsulated zeolites offer potential applications as fast-ion conductors, information storage materials, or photoconductors. 

Excitable tissue, when activated, will be found to generate currents both within itself and also in aU surrounding conducting media. The latter passive region is characterized as a volume conductor. The adjective volume emphasizes that current flow is three-dimensional, in contrast to the confined onedimensional flow within insulated wires. The volume conductor is usually assumed to be a monodomain (whose meaning will be ampHfied later), isotropic, resistive, and (frequently) homogeneous. These are simply assumptions, as will be discussed subsequently. The permeabihty of biologic tissues is important... 

Fig. 16 Three-dimensional model of the experimental single-electrode analog setup without a probe electrode. Stimulating electrode (left) has a Pt conductor surrounded by glass for insulation. The counter electrode (right) includes a horizontal conducting wire and an insulation support. A section of the glass cladding of the stimulating electrode has been removed to show the inner Pt wire...
