Platinum.
Various elements are used for making electrodes like copper, zinc, aluminium, chlorine, mercury, platinum etc. Elements for making electrodes are selected on the basis on their relative tendencies to gain and loose electrons.
Platinum is an inert metal often used in electrodes due to its stability and resistance to corrosion. It is commonly used in medical devices, fuel cells, and laboratory equipment.
Carbonarc lamps use carbon rods as electrodes, which produce an electric arc that generates light.
They are electrodes surgically-implanted into the brain
Lead (Pb) is commonly used in electrodes in car batteries as it forms lead-acid batteries, which are known for their reliability and low cost. Lead is a heavy metal that can store and release electrical energy efficiently in this application.
Pt electrodes refer to electrodes that are made of platinum. These electrodes are commonly used in various electrochemical applications due to platinum's inert nature, high conductivity, and stability in corrosive environments. Pt electrodes are versatile and can be used in different setups such as in fuel cells, sensors, and electrophysiology experiments.
Electrodes placed inside the cochlear receive the decoded signals. The 22 electrodes allow a range of different pitches to be detected. The electrodes stimulate the hearing receptors.
Common types of electrodes used for electrical brain stimulation include intracranial electrodes (such as depth electrodes or grids), subdural electrodes, and transcranial electrodes. These electrodes are used in techniques like deep brain stimulation (DBS), electrocorticography (ECoG), and transcranial direct current stimulation (tDCS) to modify neural activity for therapeutic or research purposes.
Approximately 16-20 electrodes
Approximately 16-20 electrodes
A 12-lead ECG uses a total of 10 electrodes. These include six chest (precordial) electrodes and four limb electrodes. The combination of these electrodes allows for the recording of 12 different electrical views (leads) of the heart's activity.
The calomel electrodes are usually used as the salt bridge.
