An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte or a vacuum). The word was coined by the scientist Michael Faraday from the Greek words elektron (meaning amber, from which the word electricity is derived) and hodos, a way.

Radiofrequency ablation (RFA) uses thermal energy to destroy tissue surrounding an electrode, resulting in coagulative necrosis of tissue from high temperatures 1).

A study demonstrates a time-related degradation in the external layer of deep brain stimulation (DBS) electrodes. The analyses of morphological and chemical properties of the implanted devices are relevant for predicting the possibility of hardware's impairment as well as to improve the bio-stability of DBS systems 2).
