cbseacademic.nic.in15 Faraday Cage: A Faraday cage or Faraday shield is an enclosure made of a conducting material. The fields within a conductor cancel out with any external fields, so the electric field within the enclosure is zero. These Faraday cages act as big hollow conductors you can put things in to shield them from electrical fields.

EIS involves higher frequencies, and has a tendency toward small currents/voltages, and any reduction in noise is more than welcome. The safe answer is to use a Faraday Cage whenever it is physically possible to do so. If your cell current does not exceed 1 µA, use a Faraday Cage.
