An electrode array is a configuration of electrodes used for measuring either an electric current or voltage. Some electrode arrays can operate in a bidirectional fashion, in that they can also be used to provide a stimulating pattern of electric current or voltage.
Common arrays include:
- Schlumberger (Wenner)
- Wenner alpha
- Wenner beta
- Wenner gamma
- Pole-pole
- Dipole-dipole
- Pole-dipole
- Equatorial dipole-dipole
